Data grid question

Yah I know you can set the color that appears when you roll
over the data grid with your mouse, but how do I disable the roll
over color change altogether? or at least make it
transparent.

By the way a very convenient tool when trying to make things
look right and sorting out colors, etc. is the Flex 2 Style
explorer at
.../styleexplorer/Flex2StyleExplorer.html
- this lets you play around and find your style, so to speak.
Another useful tool that I use fairly frequently, even though
I'm now fairly proficient at flex, is the component explorer, which
gives examples of the use of every control (though not every
feature). You can find it at
...sdk/explorer/explorer.html.

FillBy always fills in the same row in data grid view. How to make it fill in a new row for each click of the Fillby Button? VB 2010 EXPRESS?

Hi there,
I am a beginner in Visual Basic Express 2010. I have a Point of Sale program that uses DataGridView to display records from an external microsoft access
database using the fillby query.
It works, but it repopulates the same row each time, but i want to be able to display multiple records at the same time, a new row should be filled for
each click of the fillby button.
also I want to be able to delete any records if the customer suddenly decides to not buy an item after it has already been entered.
so actually 2 questions here:
1. how to populate a new row for each click of the fillby button
2. how to delete records from data grid view after an item has been entered
Thanks
Vishwas

Hello,
The FillBy method loads data according to what the results are from the SELECT statement, so if there is one row then you get one row in the DataGridView, have two rows then two rows show up.
Some examples
Form load populates our dataset with all data as it was defined with a plain SELECT statement. Button1 loads via a query I created after the fact to filter on a column, the next button adds a new row to the existing data. When adding a new row it is appended
to the current data displayed and the primary key is a negative value but the new key is shown after pressing the save button on the BindingNavigator or there are other ways to get the new key by manually adding the row to the backend table bypassing the Adapter.
The following article with code shows this but does not address adapters.
Conceptually speaking the code in the second code block shows how to get the new key
Public Class Form1
Private Sub StudentsBindingNavigatorSaveItem_Click(
sender As Object, e As EventArgs) Handles StudentsBindingNavigatorSaveItem.Click
Me.Validate()
Me.StudentsBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.MyDataSet)
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MyDataSet.Students' table. You can move, or remove it, as needed.
Me.StudentsTableAdapter.Fill(Me.MyDataSet.Students)
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Me.StudentsTableAdapter.FillBy(Me.MyDataSet.Students, ComboBox1.Text)
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Me.MyDataSet.Students.AddStudentsRow("Jane", "Adams", "Female")
End Sub
End Class
Get new key taken from
this article.
Public Function AddNewRow(ByVal sender As Customer, ByRef Identfier As Integer) As Boolean
Dim Success As Boolean = True
Try
Using cn As New OleDb.OleDbConnection With {.ConnectionString = Builder.ConnectionString}
Using cmd As New OleDb.OleDbCommand With {.Connection = cn}
cmd.CommandText = InsertStatement
cmd.Parameters.AddWithValue("@CompanyName", sender.CompanyName)
cmd.Parameters.AddWithValue("@ContactName", sender.ContactName)
cmd.Parameters.AddWithValue("@ContactTitle", sender.ContactTitle)
cn.Open()
cmd.ExecuteNonQuery()
cmd.CommandText = "Select @@Identity"
Identfier = CInt(cmd.ExecuteScalar)
End Using
End Using
Catch ex As Exception
Success = False
End Try
Return Success
End Function
In closing I have not given you a solution but hopefully given you some stuff/logic to assist with this issue, if not perhaps I missed what you want conceptually speaking.

Extra row in data grid

after I load a object into data grid created from a web
service it will always seem to create a new blank row. When I get a
error after clicking on it, it always says "-1" for the rows count.
when I shrink the size of the datagrid it elminates some of the
extra row, but still there is a bit of it showing. how do I resize
the datagrid so it doesn't spit out a extra row, or a part of one.
http://www.ctrlzsc.com/other/pic.png
this is a pic showing the extra row, just look where my badly drawn
arrow is pointing to.

hi, xyco45
you can set the dataGrid's height and the rowHeight. In my
experience, for example, first, you set the headerHeight="25" and
rowHeight="22", the height will be setted
(headerHeight+rowHeight*(rowNumbers)+1) or
(headerHeight+rowHeight*(rowNumbers)+2), I thought this question
will be solved.

My custom Tool tip on spark data Grid don't work ?

I want to add panel component as my tooltip for each row in my Spark DataGrid. So when mouse rollover the user can see the information for each the ship. I want a panel as my tooltip for dataGrid cause I want to organize my data neatly and also place a image in the panel.
I came across :http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf60d65-7ff6.html where they show an example of "Implementing the IToolTip interface" using the panel.I tried manipulating the codes but it didt work for my spark dataGrid.
So my question :
Can some one pls show me how I can use the Panel as my tool tip for each row in spark data grid.

Ok I was getting ready to post the renderer code and then found the problem. I had copied this code from another renderer which had contentBackgroundAlpha=0 in the MXAdvancedDataGridItemRenderer tag. When I removed it, the style of the TextArea worked as intended. Your comment helped me to take a closer look at the renderer code, so thank you.

Reading a csv file and bind to a data grid

hi. doing a school project and been searching. the application reads a csv file from c:\stocklist.csv, and then this in a button called btnLoadData, and now need to read in a data control called DmgDisplayData. do i put the code in the button, or in the
data grid. been searching, but cannot seem to find any thing. so, where do i put the code, in the data control, and does any one have an example code how to read into the data fields. also need to have one field, able to edit, the other three or four fields,
read only. can any one help me out. never covered this in the subject, but did do file streams a few years ago in vb, but usin g c#,a dn the help in visual studio, not that helpful, with a blind person using a screen reader, jaws for windows from http://www.freedomscientific.com,
and using visual studio 2013 community edition. can any one help me out, been searching and trawling about 15 to 20 pages so far, and did try a couple of sites, but could not find, any help. thanks. the application is to read a csv file from a button, and
load into a data grid, then have a message box, saying file load successful, then have one field, order on as edit, but the other fields, read only, so do i need the navigator buttons, for next, back, previous, etc, and how do i code that as well. not to do
it for me, want to learn, but maybe some sample code, did do navgiator controls, years ago for a vb project, but need the c # example for that, thanks. then you have a button, Save data, that saves the csv file in the data grid. so can google for that. then
have a toolbar, with a button saying, Sort Items, a tool strip, and when you click on that button, you have a drop down list, of three items, then a sort button, which will then sort the array in the data grid. so, do i need another form, or just do the combo
box as an invisible control, then just refrence, that in the toolbar. so need to use th file class and an array, learnt about single and multi arrays. any ideas. thanks.
http://startrekcafe.stevesdomain.net http://groups.yahoo.com/groups/JawsOz

Hi Marvin,
-->where do i put this, in the data grid click event. or in the form load event. thanks.
You could use this code after you initialize the DataGridView. you could put it in the form load event.
-->what about how get the tool bar and the combo box and another button, then sort from the combo box on the array for the collumns, for to set focus to the first read collumn for the data grid. how do i do that, close the parent form, and have another
form on the toolbar.
Since this is another issue of this thread, I would recommend you posting it with
another thread. We will focus on that thread to help you. Thanks for your
understanding.
BTW, Before you asking questions, I suggest you could learn to make it by yourself. You could begin to learn winforms in MSDN articles:
https://msdn.microsoft.com/en-us/library/dd30h2yb%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396. Or Google it, you will get many answers. In that way, you will learn more from the questions.

How to add a Hyperlink to open popup in dynamic data grid?

Hi,
I am a new bie in FLEX, the question which I am asking might be very easy but i am not able to find solution to it. Please can some one help me.
I am creating a data grid dynamically using action script code now I want to add a Hyper link to couple of columns in a row. How can I do it in FLex?
Thanks.

HI Prashant,
Thanks for the reply.
This is what I am currently doing right now:
for
(var i:int=0; i<colNameList.length;i++) {
var headerText:String = colNameList[i] + "";
callSellGridCol = cols[i];
callSellGridCol.headerText = headerText;
if(headerText != null && headerText == "RIC"){
var myRenderer : ClassFactory = new ClassFactory(com.db.carving.synthetic.dma.view.UrlLinkRenderer);
In My Renderer class :
public
class UrlLinkRenderer extends LinkButton{
public var clickFunction:Function;
public function UrlLinkRenderer() {
super();}
// Override the set method for the data property.
override public function set data(value:Object):void{
super.data = value;
if (value != null){
label = value[DataGridListData(listData).dataField];
else{
label =
super.invalidateDisplayList();}
Now what i want is to add a new Event Listner to this object so that I can click it?
In your suggestion you said:
var classFacory:ClassFactory = new ClassFactory(LinkRenderer); // here LinkRenderer is any mxml/ as file Having Link Button defined.
Where should be the Link button defined??
Thanks.

Advanced data grid and grouping

This is probably a basic questions, so hopefully someone will
know the answer. I have an advanced data grid that works find a
follows:
<mx:AdvancedDataGrid id="adgReportList"
horizontalCenter="0"
y="28" width="485" height="500" dataProvider="{reports}">
<mx:columns>
<mx:AdvancedDataGridColumn headerText="Proposal Number"
dataField="PROPOSAL_NUMBER"/>
<mx:AdvancedDataGridColumn headerText="Report Title"
dataField="REPORT_TITLE"/>
<mx:AdvancedDataGridColumn headerText="Report Start Date"
dataField="PERIOD_BEGINING"/>
</mx:columns>
</mx:AdvancedDataGrid>
So the data coming back seems to be fine. But when I try to
group the data as follows, nothing shows:
<mx:AdvancedDataGrid id="adgReportList"
horizontalCenter="0"
y="28" width="485" height="500"
initialize="gc.refresh();">
<mx:dataProvider>
<mx:GroupingCollection id="gc" source="{reports}">
<mx:grouping>
<mx:Grouping>
<mx:GroupingField name="PROPOSAL_NUMBER" />
</mx:Grouping>
</mx:grouping>
</mx:GroupingCollection>
</mx:dataProvider>
<mx:columns>
<mx:AdvancedDataGridColumn headerText="Proposal Number"
dataField="PROPOSAL_NUMBER"/>
<mx:AdvancedDataGridColumn headerText="Report Title"
dataField="REPORT_TITLE"/>
<mx:AdvancedDataGridColumn headerText="Report Start Date"
dataField="PERIOD_BEGINING"/>
</mx:columns>
</mx:AdvancedDataGrid>
Thanks for any help.

Advanced Data Grid in Action Script

ok so I am now generating an AdvancedDataGrid in Action script as I will have dynamically created columns based on specific user
My grid code looks like this
private function generateGrid():void
var clms:Array;
myADG.dataProvider=gridData;
myADG.width=
this.parentApplication.adgPanel.width-20;myADG.height=
this.parentApplication.adgPanel.height-39;myADG.visible=
true;myADG.x=0;
myADG.y=0;
myADG.designViewDataType=
"flat";myADG.horizontalScrollPolicy=
"on";myADG.verticalScrollPolicy=
"on";myADG.lockedColumnCount=6;
myADG.sortExpertMode=
true;myADG.headerWordWrap=
true;
My question is this, in my MXML Grid that preceded this I hand this line
click="{populateChildren(adg.selectedIndex)}"
How do I add this functionality to my new AS Advanced Data Grid??
populateChildren is a function that allows me to set the specific row as an object and share amongst other other modules based on the grid selection.
        private function populateChildren(loc:int):void
          selected = Object(gridData.getItemAt(loc));
          this.parentApplication.populateChart(selected);
Thanks in advance for any help.

The complete sample code contains 5 WebService calls that populate List collections views.
Given these services are not exposed externally, I can't see how that would be more helpful it would actually cause more errors.
But as usual with being new to Flex and AS I have found the root of the problem....ME    it's always something so silly and easily overlooked.
myADG.addEventListener(MouseEvent.CLICK,populateChildren());
should read:
myADG.addEventListener(MouseEvent.CLICK,populateChildren);
and for completeness my function needed to look like this
private function populateChildren(e:Event): void
selected = Object(gridData.getItemAt(myADG.selectedIndex));
this.parentApplication.populateChart(selected);
completely back to operational again.
Thanks for taking the time to look into this a bit, sorry for the trouble, but at least I will recognize that error, I had never seen it up till now.
Thanks again.

Data grid hidden

hi. okay, have a two click buttons, and they are supposed to write to the xml and read the xml file, and then transform it to the application, when i click on the Current count or On Order buttons, when you click these buttons, have a grey background colour,
foreground blue colour, and have a different font of Verdana and Century School book. it keeps hidden, when i click these buttons, when i load the data grid from the csv. so, how do i make sure that, it is not hidden, when i click on it. will paste the
two button click events. have tried googling this, and did not find any thing. so will paste the code below.
marvin.
        // This function will display the Current Count data grid column to change the style sheet for this click event.
        private void btnCurrentCount_Click(object sender, EventArgs e)
      // Design a data table and write and read the xml documents to the data grid columns selected.
      // Set up the data set.
      DataSet ds = new DataSet();
      // Set up the data table.
      DataTable dt = new DataTable();
      // Ad the data table to the data set.
      ds.Tables.Add(dt);
      // Write the xml document to the data grid column.
      ds.WriteXml(Application.StartupPath + ("CurrentCount.xml"));
      ds.ReadXml(Application.StartupPath + ("CurrentCount.xml"));
            // Set up the data table and the data set and set to 0.
      dgvDisplayData.DataSource = ds.Tables[0];
          // Set focus on the Data Grid Column.
      dgvDisplayData.Focus();
      System.Xml.Xsl.XslCompiledTransform xslTransformer =new System.Xml.Xsl.XslCompiledTransform();
      xslTransformer.Load("CurrentCount.xsl");
      xslTransformer.Transform("CurrentCount.xml", "CurrentCount.html");
    // This function will display the On Order data grid column to change the style sheet for this click event.
    private void btnOnOrder_Click(object sender, EventArgs e)
      // Design a data table and write and read the xml documents to the data grid columns selected.
      // Set up the data set.
      DataSet ds = new DataSet();
      // Set up the data table.
      DataTable dt = new DataTable();
      // Ad the data table to the data set.
      ds.Tables.Add(dt);
      // Write the xml document to the data grid column.
      ds.WriteXml(Application.StartupPath + ("OnOrder.xml"));
      ds.ReadXml(Application.StartupPath + ("OnOrder.xml"));
      // Set focus on the Data Grid Column.
      dgvDisplayData.Focus();

Data Grid Sort Within Portlet

I have a portal with a portlet that contains a search form and a data grid. I have set the sortable attribute on the column to true. The sort action gets the filter service and passes it to the DB control.
I cannot seem to get the sorting to work. The output from getSortFilterService().getDatabaseFilter(getGridName()).getOrderByClause() is always empty no matter which column I click.
Is there something special I have to do because of the portal/portlet?
Can someone give me a tip (or two). I realize this is a novice question but I am learning as I go and would appreciate any help.
Edited by markml at 09/20/2007 9:41 PM

I figured it was locking up the browser. I submitted a bug ticket several months ago concerning the same issue. If you have "enableviewstate" set to true on a datagrid and you are using the PT web controls, then the browser will lock up. It all depends on the number of rows and columns you have in the datagrid; unfortunately, I don't know the fatal number.
However, what causes it is how Plumtree manages the viewstate itself for a datagrid. In a nutshell, they have to remember the viewstate for each single item in the grid. And the algorithm they use is extremely slow. The browser's scripting engine basically locks up because of the length of time it takes.
Unless you absolutely need it, I would just turn off the viewstate. It disables some fancy features of the datagrid, but you can still build workarounds.
Hope this helps/clarifies things for you!

Data Grid, how to avoid unintentional data manipulation

Hi,
Is there a option to avoid unintentional writing in the data grid ?
And if not, please implement such a toggle button for Security reasons.
Andre

Hello K.
thank you for interesting in and care about my mental health.
I'm alive and kicking.
But if I follow your logic the developers of TOAD must have a real big (mental) problem.
They are obviously that kind of paranoid that the say:
“Our data grid is protected always against data modification as long as the user does not explicitly put the rowid to the column list to undoubtedly make clear that they want to manipulate some data.”
I asked them if this is really needed, because in SQL Navigator there is just a simple button to toggle between RW and R only (What I definitely prefer) .
And the said YES – to avoid unexpected / accidentally changes.
Do you find that still strange?
If yes these guys must be more ill then the two of as can imagine.
But I’m very sure that they are alive and kicking too.
By the way - one of my questions remained unanswered:
Did you ever analysed other tools to pick the best feature of them in order to implement they into your tool?
If not, believe me you should. It is worth the effort.
Otherwise it is quite possible that you will take an unfounded amount of time till you will have reached a equivalent level.
Or do you want to be behind the others for eternity?
If you had the task to develop an new car would it ever come into your mind to build it with without a backward gear and simply to wait until someone requests something like that.
Some (useful) standard has been set before you came up.
What about a little less self satisfaction and a little bit more respect.
That’s my advice for you (also) beyond the sqldev tool .
Regards
Andre

Data grid for jsp applications

Someone knows where i can get a good data grid (free or cost ) for JSP applications

I just stumbled across this thread as we are developing a stateless BSP application and plan to use model binding in it.
For our application the part of the models state that changes is displayed in the view in form fields, so our idea is to reload the model from the db in the doInitattributes-Method and let the model binding do the rest of the work filling in the values that changed in the view. It seems to work so far - so i guess persisting the state of the object to the db is only necessary when something changed that is not part of the view, right?
My second question is on Brians recommendation to use MVC only at exactly one level. Is using Sub-Controllers a problem when they have got their own model? I guess the extra work Brian mentions is all about telling the subcontrollers which model to load, right?
It would be good to know if there are any serious pitfalls when using a hierarchy of controllers instead of a controller with a collection of views.

Please help me on Data Grid or Smiliar thing in JSP ?

I am developing a J2EE application where I have the following scenario:
On a JSP Page there's a button 'Fetch' which when clicked fetches some dynamic records based on some criteria from the Oracle DB and displays them on the JSP page.
Now these records, say 50, have to be displayed in a table like format where the first column of every row will be a radio button.
Now as I click any one radio button and click on the submit button below my records table, the next page should read the entire record corresponding to that particularly clicked radio button.
In .NET , I have heard of Data Grids API doing this, but in Java I don't find any solution on how to implement this UI situation.
Any custom tags or API known to you for this, please share.
Awaiting for your creative responses. :)

I think you all aren't able to interpret my problem statement correctly.I don't see any evidence of that. All I see is evidence that you didn't understand any of the responses.
If DataGrids and their action triggering would have been a plain HTML/Javascript thing then perhaps there hadn't been separate APIs in other web languages for this.The conclusion is that you should be using one of those, such as JSF, as you were already advised in all those inadequate responses. Alternatively you can continue to fantasize that such a facility is present in JSP when it isn't.
just thought if some geek could help me out on developing this specific APIYou may have thought it but you didn't ask for it. You asked for 'Any custom tags or API known to you for this, please share'. You got the answer to the question you asked.
I've no option but to proceed on my own.I agree.
