DataGrid and DataSet

Does anyone know how to bind a dataSet to a dataGrid in
Director?
In Flash it's easy since you simply set the binding tab on
the Components inspector to the DataSet... but if I import these
flash components to Director there is no way other than using Lingo
(or script) to bind these two together. Any ideas?

That *is* a very interesting article. Unfortunately, it
doesn't mention anything about DataSets. I haven't had any trouble
getting my data into my flash application. I've also been able to
put it into a DataGrid pretty easily (although not quite as
elegantly as that example did).
The problem is that I'm having issues when I introduce a
DataSet for filtering. I can't get the data from the DataSet into
the DataGrid like I want it. I haven't been able to hide the 'id'
column of my data and the column names unfortunately are *exactly*
what the Object property names are. I was hoping to put
user-friendly column headers on their like 'Product Name' rather
than 'name' or 'Style Number' rather than 'styleNumber'.
Also, the concept of a schema is still somewhat beyond me. I
tried changing the schema for my productDataSet to this and I got
the data to display. I added 'name, 'styleNumber', and 'id'
quote:
<-->dataProvider : Array
<-->deltaPacket : DeltaPacket
<-->items : Array
<-->selectedIndex: Number
<-->name : String
<-->styleNumber: String
<-->id : Integer
I have tried radically different shemas (schemae?) that seem
to also get the data in there but I don't really understand what
i'm doing here and I feel like I'm asking for trouble not knowing
how this stuff really works.
And, like I said before, i want to hide certain information
that's in the DataSet so that it doesn't get displayed. I'd also
like to Have some user-friendly names rather than the actual
field/property identifiers.

How to delete a selected row from datagrid and how to create a datagrid popup

hi friends,
              I am new to flex.i am doing a flex4 application,i need help for this.
            i am having a data grid with columns.i have two questions.
           Ques 1: when i selected a partiuclar row from a datagrid and click delete button means that record will delete from the datagrid and DTO from the cloud tables also.
            Ques 2: when i save the data grid values using save button means that data will store in respective cloud DTO which is related to the datagrid,
                 My requirement is i am using a search button when i click the search button it will show a datagrid that datagrid will contain the previous datagrid datas which is saved in the cloud.
REQUIREMENT example: first screen:           i am using with data grid 3 columns (Student Roll number ,Student Name,Student pecentage)---->save--->data will store in cloud DTO.
Second screen:                search button ----> it need show datagrid popup.it will have data which we saved in the first screen with same columns(Student Roll number ,Student Name,Student pecentage).
This is my requirement.
Any suggession welcome.
Thanks in advance.

Lets break the problem statement in multiple steps
1. We need a way to know the selection on all rows.
2. We need the association of the checkBox with the data
The solution is to use a arrayCollection/array that holds all the instances created for checkbox.This collection should be a property of component containing the datagrid. We need to use a custom component implementation or inline ItemRenderer. The way you have used is called dropinItemRenderer. Preferaly use custom component implementation and add the instance to the arrayCollection at CreationComplete. Make sure you use addItemAt so that you add the instance in the same row as the data. To get rowIndex the custom Checkbox should implement IDropInListItemRenderer. You could iterate this collection to check all the instances that are checked.
Note: This is the approach considering your dataprovider doesnt have a selection field.

How2 load xml into datagrid, and create realtime search of datagrid data

I wanted to be able to load xml data into a datagrid and then create a searchbox that would search in real time (as person typed) from any part of the datagrid. Does anyone know of any as2.0 component that can do that easily? If not, i would like to try to tackle this the old fashioned and use this to teach myself as2.0 advanced coding. can someone point to a step by step or explain how i might get this accomplished? from loading the xml to putting the node info into the datagrid, to being able to search it in real time. This is part of a project that i was given that has some serious consequences if i botch it. Please help! Thanks so much!

GridView vs DataGrid and gateway

Used to use DataGrids and in a template field Hyperlink, the portal converts the link to a fully gatewayed link... GridView Hyperlinkfield does not get "gateway converted"? Thoughts? Guess I could use a TemplateField, but was hoping to use a more default solution.
EDIT: it appears that a template column with a hyperlink in a GridView does not get "gateway converted" either, hmmmm. Back to tesing and tinkering
EDIT: I am a moron....have to set the gateway prefix in teh Web Service.....jsut shoot me now! TGIF!

Doh..built my web app in VS2008 w/o using the app accel / AquaLogicWCLoader. It started out as a LINQ o/r mapping experiment - but am trying to take a step further and get into the portal. I'll tweak the web app (referenes to idk and wcloader, web forms into partial classes inheriting from BEA.ALI.Web.UI.ALIPortletPage) and see if that fixes. I'll keep the group posted.
Bah-zing! It worked. As usual, thanks again, Joel!

DataGrid and labelFunction

Hi all!
I have a DataGrid, and I have two columns where i want to manipulate the data shown. I tried using a labelfunction, but it turns out the labelfunction is called each time I focus out, and not only when the DataGrid is initialized.
I've seen theres an initialize for DataGrid, but how can i use this to manipulate the data from my two columns?
Sincerly

How do you wrap an object? It depends on how you are getting your data. If
you are using RemoteObject or can control the data type being sent over the
wire, I would simply add a new getter to the data class.
The most rudimentary way is something like this: Say you had a ShoppingCart
record:
class ShoppingCartRecord
    public var catalogID:int;
A wrapper class might look like:
class DisplayableShoppingCartRecord
    public function DisplayableShoppingCartRecord(orig:ShoppingCartRecord)
        original = orig;
    public var original:ShippingCartRecord;
    public function get catalogID():int
        return original.catalogID;
    private var _displayName:String;
    public function get displayName():String
        if (!_displayName)
            _displayName = yourOldLabelFunction(orig);
        return _displayName;
Then at some point, you loop through the original data set and instantiate
the wrapped versions and pass that dataprovider to the datagrid.

Synchronization between datagrid and chart Item

Hi
In my application, I have a datagrid and corresponding bar
chart. there is a toggle button through which I can switch between
chart and data grid.
Now I want to synchronize both.
for example If I select any 3 rows in data grid then it
should selects 3 bars on the chart also.
can any body help me in that?
Thanks

Hi,
U need to have a combo box renderer something like:
In the object that u are populating the data provider of the
data grid, add 2 fields:
listOfFields & selectedField.
<mx:HBox horizontalScrollPolicy="off"
verticalScrollPolicy="off"
xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
public var itemSelected: Object;
]]>
</mx:Script>
<mx:ComboBox id="combo"
dataProvider="{data.listOfFields}"
selectedItem="{data.selectedField}"
change="itemSelected=combo.selectedItem;"
updateComplete="itemSelected=combo.selectedItem;">
</mx:ComboBox>
</mx:HBox>
Now, loop through the list of objects that u get from
back-end and keep setting the 2 new properties (listOfFields &
selectedField). For setting the value of selectedField, u need to
loop through listOfFields to match the fieldId.
Hope that helps,
Cheree

Using same returned data to create datagrid and pie graph

I am trying to find a good example or information on creating
charts, initially pie graphs. I will be getting the data from a
MySQL DB via a HTTPService call to a PHP script. I would like to
use the same HTTPService call to make a datagrid and build a pie
graph. My datagrid is working fine.
All of the examples I have found show the app with an
internal data source that's hard coded into an array (
http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDo cs_Parts&file=00001234.html).
I did search this forum, but it seems most people are just looking
for dynamic pie graphs and there isn't enough in the entries for me
to go off of.
The data returned to the MXML app looks like this:
<auditdata>
<riskdata>
<core>core number here</core>
<subcore>subcore number here</subcore>
<mdata>mdata here</mdata>
<risk1>number here</risk1>
<risk2>number here</risk2>
<risk3>number here</risk3>
</riskdata>
<riskdata>
<core>core number here</core>
<subcore>subcore number here</subcore>
<mdata>mdata here</mdata>
<risk1>number here</risk1>
<risk2>number here</risk2>
<risk3>number here</risk3>
</riskdata>
</auditdata>
When the data is returned, everything under <riskdata>
is put into a datagrid. What I'm looking to do in the pie graph is
this.
Create a 2 different pie graphs for each riskdata (there will
only be 2). The first pie graph will be of the three "risks" (where
their total number equals 100% of the graph). The second pie graph
would be "core - subcore" and risk1 (where the two values total
equals 100%of the graph). I hope that makes sense.
Any guidance would be truly appreciated.
Thanks,
Chris

Does anyone have any ideas on this?

Autosuggest and dataset notifications / callbacks

Hi,
Arnout thanks for your answer on using Javascript arrays with auto suggest. Spot on in terms of what I needed to do in temrs of Spry datasets and I've got that part up and running now.
The next question follows on from that.
When a user clicks on an auto suggest from the Spry dataset thus generated it fills in the input text field as expected. Does it do anything special with the Spry dataset such as setting the current row id / number and / or trigger any notifiers? What I'd essentially like to do is have something that detects when a user has chosen a suggestion from auto suggest list and then pull the values from another column of the dataset / array for the same row id / number and feed that into another javascript function I have written. Possibly a notifier / callback setup ?
Thanks
Phil

Seems like I completely missed your question here. I once required the same kind of functionality inside my autosuggest. I extended the autosuggest to do a fire my callback function. This is a more secure solution that adding a click handler.
Extend the following method:
Spry.Widget.AutoSuggest.prototype.setValue = function(str)
     if (!this.textElement)
          return;
     this.textElement.value = str;
     this.showSuggestions(false);
     if(this.callback){
          this.callback( str );
Than in your constructor you can add the option :
callback: function( value ){ do stuff };
If i miss these questions in the future don't hesitate to PM me

Datagrid and Inline Item renderer problem

I have a datgrid with two inline item renderers. The dataprovider for my DG is a nested object (objects within objects within objects i.e 3-layered).
Main Object - 1st Level
                          |
              2nd Level Object 1
                                |
                            3rd level object '1' => ('name'=>somename,'id'=>someid)
                            3rd level object '2'
                            3rd level object 'n'
             2nd Level Object 2
                                |
                            3rd level object '1' => ('name'=>somename,'id'=>someid)
                            3rd level object '2'
                            3rd level object 'n'
I use 2 item renderers (one for each datagrid column) which loops thro the 2nd level object1 and 2 respectively (the 2nd level object is a dynamic array of objects, in that the number of objects within keep changing).
Within the item renderer I loop thro the 2nd level object using a foreach and then display the data. The data is a linkbutton, which when clicked , calls a remote object function to delete the data from the database
now on the result event of the remote object function call, i call the function to repopulate the DG, so that the updated data is displayed.
When i click on the linkbutton in the first row, the backend works perfectly fine (the data gets deleted from the database and the refreshed data is sent back), but for some reason, the deleted data suddenly appears in the 2nd row.
When i delete it from the second row, it appears on the 3rd row (nothing happens in the backend since the data is already deleted).. and so on, till it appears on the last row and then the DG looks exactly the way it shld have looked after the first delete.
This is just the beginning. The second item renderer also displays a linkbutton, which when clicked, displays that data in the previous column (the one where this data can be deleted). When i click on 1st row, the data gets added in the previous column of the second row .. and so on..
Basically, my DG is acting really weird. I overrided the set data function in the item renderer to refrsh the data and called its invalidateDisplayList. I also call the Datagrid's invalidateDisplayList function after each refresh. The behavior remains the same.
Please help me on this ...

Datagrid and multiple ItemRenderer

What I would like to do and haven't been successful is add a column to a Datagrid at runtime. Each cell in that column is going to be different based upon user data. The first column is populated based upon a user query then another query (i.e. RESTful query) is made to mashup some data.
I wanted a button (mashup data) to appear in the column enabled if data was available and disabled if data was not available.
I was doing something like this:
My MXML file has this:
        <mx:DataGrid id="dg" dataProvider="{ModelLocator.getInstance().list}" itemClick="itemClickHandler(event)" left="10" right="0" bottom="0" top="50" editable="true" >
            <mx:columns>
                <mx:DataGridColumn headerText="Name" dataField="name" editable="true" />
                 <mx:DataGridColumn headerText="Data" dataField="someData" itemRenderer="ActionButtonItemRenderer" />
            </mx:columns>
        </mx:DataGrid>
ActionButtonItemRenderer.as file:
    public class ActionButtonItemRenderer extends Button
        public function ActionButtonItemRenderer()
            super();
            label = "Show Data";
        override public function set data(value:Object):void {
            if (null == value.myData) {
                label = "";
                this.enabled = false;
        // Handle the search button event.
        override protected function clickHandler(event:MouseEvent):void
            // Code omitted here...
It works but when I use my mouse wheel to scroll through the records the buttons get all hosed up and the enabled buttons become disabled. It's weird.
Thanks!

You create an ArrayCollection or XMLListCollection and populate it initially with perhaps data that would represent "no data".
Then if your queries return real data, the dataProvider object now "has data".
The itemRenderer does the appropriate thing if there is not is no data.
You don't generate the button in the dataProvider, you just get the label and visible property value etc. from the dataProvider.
If this post answers your question or helps, please mark it as such.

Dynamic Forms and Datasets

I have created a dynamic form in LC8.0. Distributed it to our server via Acrobat Pro 8.o. The users have Reader 8.0. There are two subforms on the page, both of which are tables which can be expanded using an addInstance button.
Everything works well with single row entries - I receive the returned data in a mailbox, open up the file which then populates a dataset with the information from both tables. This can then be exported to an Excel spreadsheet.
However, when the addinstance button is used by the user and an additional row of data is added to either of the tables, the following message box error appears when I try to add that data to the dataset:
"...the form fields do not match the fields in the dataset"; followed by
"Failed to add the returned form to the dataset file. Error code = 11".
Does anyone have any idea what I'm doing wrong? I'm not a programmer, so please provide as much information as you can.
Any help appreciated. Many thanks.

Hi Jerry
I think I managed to solve this one - though not sure I remember quite how I did it. I think it was by ensuring that only those items I wanted to export from the data set had their data bindings set to Normal. Absolutely everything else was set to None - so check that the subform that holds your addInstance button is also set to None.
In opening the returned form a message box may appear stating:
"Fields in the 'formname' do not exactly match the fields in the template in the data set. Do you really want to add the form to the data set?".
When you've added it you will notice an additional column to the far left of the data view panel of the data set with the header "Has Different Fields". Depending on whether the data submitted had one or more instances added will determine whether the column has a Yes or a No in it. If there were multiple entries in that particular form, you will only see the first one until you've exported the data to your other application. The "Yes" or "No" isn't exported.
Good luck

2 way databinding between DataGrid and DropDownList

I am not getting anywhere with what I thought is the most simplest basic thing in the world.
I have a ArrayCollection "employees" which is used to fill a DataGrid. The department is listed as an Integer value. I would like to display however the name of the department, which is in a second ArrayCollection "departmentsArray". So the itemRenderer (which is not yet implemented in this code) needs to match the "idn" value with the "departmentid" value and then display the name of the department. However, when the user clicks on the DropDownLists and selects a new department, the departmentid value in the employee array needs to get updated too.
I am assuming that this can be done with 2 way databinding, but I am not getting this to work and would greatly appreciate if someone could show me how the code would have to look for this.

Thanks for the info.
I've only seen info about Snow Leopard syncing (and it doesn't really specify 2 way) to Exchange (which is not LDAP)
Addressbookserver (www.addressbookserver.com) is also not LDAP.
I really need this to work (2 way sync) with an LDAP server.
Thanks.
