Problem: Array to datagrid

Hey Guys,
I got a problem getting an array into a Datagrid.
My XML
quote:
<uitvoering>
<naam>Hocker</naam>
<hoogte>40</hoogte>
<breedte>61</breedte>
<diepte>57</diepte>
<stof>
<naam>Nevada</naam>
<prijs>169</prijs>
</stof>
<stof>
<naam>Sirius</naam>
<prijs>169</prijs>
</stof>
.. (more)
If i put this into a Datgrid it comes out as the following
[Key-naam] ---- [Key-hoogte] ---- [Key-breette] ...
Value-naam---- Value-hoogte----Value-breette...
Value-naam---- Value-hoogte----Value-breette...
... lots more :P
Wich is good for one of the views i have to make but for the
second one i have to do something quite difficult, in my eyes at
least . I want the second view to look like this.
[Key-naam] ---- [
Value-stof.naam 1] ---- [
Value-stof.naam 2] ...
Value-naam----Value-stof.prijs
1-----------------Value-stof.prijs 2-----------...
..lots more
I kept the original key names altho there in Dutch but the
structure is in the quote above, I hope you get the idea, its
rather hard to make a nice grid :)
But is this even possible in flex? if it is can somebody
please give me an example or a link to a page with a tutorial or
something like that!
Thanks in advance!

sue no problem:
I load my xml like this :
<mx:HTTPService id="modelSpecs" url="modellen.xml"
useProxy="false" />
then i open a datagrid an give it a provider
<mx:DataGrid x="10" y="10" id="dgPosts" width="562"
height="473"
dataProvider="{modelSpecs.lastResult.model.uitvoering}">
</mx:DataGrid>
And this works fine for the first method!, but i truely have
no idea how to get it like the second example i posted.
ideas anyone?

Array to DataGrid not working. Please help before I lose my mind (and my hair) completely.

Hi,
I'm new to the whole flex/as/flash builder, but I'm trying to do a seemingly simple thing and it's not working.
Flex Mobile project has a button and data grid. When I press the button a 2 dimensional array is build with random numbers. Then I want to show the array on datagrid.
The array does get build but it's not showing up on data grid.
Any help would be appreciated as I've spent lots of time on this without any solution.
Thanks,

Brick Wall Problem: Array of Clusters, Size of array from reference

Good Morning Forums,
I have hit a brick wall with my application and I am hoping somebody can help!
I have an array of clusters of indeterminate size (the cluster is generic, data contained not relevant.).
Inputs to the VI are: a reference to the array, and a variant containing the data.
My problem is I need to determine the array size from these two inputs and I cannot find a way to do it!
If the array contained a standard data type I can use the class name property to determine data type, and the size of the array returned from "select size" property to determine dimension size. With this information i can cast the variant into the correct data type and use this to determine the size of the array. If the data is a cluster the class name simply returns "cluster" so I cannot cast the variant and therefore am unable to determine the size.
I am not worried about casting the data (once i determine the size this bit is no issue), I just need to determine the size (and preferably number of dimensions) of the array. Can this be done?
Cheers for any help

There seem to be a couple of potential solutions.:
#1 if the varient is created within LabVIEW you can wite size(s) to a varient attribute. This would be pretty straightforward and easy to implement- I imagine you would have thought of that so you may not have access to the code writing cluster to varient and it gets a bit trickier.
#2 cast the varient to string and return string length- this should give you a measure of total size and you would need to know the size per element of cluster (just cast one instance of cluster array to varient and then to string with size and size++) but this only returns the total size of the array since nDim arrays are actually stored sequentially.
Hope this helped

Xcelsius component output problem (array)

Mx_internal_uid problem with advanced datagrid

I have a XML structure like this:
<Projekti ...attributes>
<Tehtava ....attributes />
<Tehtava ...attributes />
</Projekti>
<Projekti...>
...etc
And I'm populating advanced datagrid with this hierarchial
data, so I can get a tree view in datagrid where there is Projekti
-nodes and inside them is the Tehtava-nodes.
Problem:
When I bind the XML, and the hierarchialdata (that is created
from the XML) flex automatically adds
<mx_internal_uid>a324235351514......</mx_internal_uid>
-nodes inside of the Projekti-nodes. And this causes empty folders
added in a tree view when user clicks them.
Is there a simple way to:
a) prevent thos uid-nodes being created?
b) filter thos <mx_internal_uid>-nodes out from the
dataprovider of the advanced datagrid?

I know this is way after-the-fact, but I just ran into this problem myself today. I found that it generated the mx_internal_uid if the node I was selecting was an XMLList instead of XML. A simple cast fixed the problem.
P.S. "And this causes empty folders added into a tree view when user clicks on them." makes perfect sense when you're using the XML inside a <mx:Tree>. As soon as you select the item (whether by clicking or programmatically), you get extra nodes in the tree.

(URGENT) Skining problem of components (datagrid & combobox)

Hi,
I m using FLASH CS3, I used Datagrid and Combobox component from components panel, and simply add some data inside in that.
setupComboBox();
function setupComboBox():void
    cb.setSize(200, 22);
    cb.prompt = "Select a Credit Card";
    cb.addItem( { label: "MasterCard", data:1 } );
    cb.addItem( { label: "Visa", data:2 } );
    cb.addItem( { label: "American Express", data:3 } );
import fl.controls.DataGrid;
import fl.controls.dataGridClasses.DataGridColumn;
import fl.data.DataProvider;
import fl.events.DataGridEvent
var dp:DataProvider = new DataProvider();
dp.addItem({col1:"item 1.A", col2:"item 1.B", col3:"item 1.C"});
dp.addItem({col1:"item 2.A", col2:"item 2.B", col3:"item 2.C"});
dp.addItem({col1:"item 3.A", col2:"item 3.B", col3:"item 3.C"});
dp.addItem({col1:"item 4.A", col2:"item 4.B", col3:"item 4.C"});
myDataGrid.addColumn("col1");
myDataGrid.addColumn("col2");
myDataGrid.addColumn("col3");
myDataGrid.dataProvider = dp;
myDataGrid.setSize(300, 200);
myDataGrid.move(10, 10);
It seems working fine.
My problem is , I want two different type of skining of two different component(DataGrid & Combobox). in the same fla.
.. e.g if datagrid have gray color skin type and combobox have black color skin type.
Can any one have any Idea?

Thanks for reply..
@kennethkawamoto2
I already implemented that thing , that u suggest, The Main problem of this component is CellRenderer, what's the solution of it ?
If i apply this
cb.setStyle("upSkin", ComboBox_upSkin2);
cb.setStyle("overSkin", ComboBox_overSkin2);
cb.setStyle("downSkin", ComboBox_downSkin2);
Its change the header of Comobo box pattern, but the rest part e.g cell is remaining the same.
I tried like this also
cb.setStyle("upSkin",CellRenderer_upSkin2)
cb.setStyle("downSkin",CellRenderer_downSkin2)
cb.setStyle("overSkin",CellRenderer_overSkin2)
cb.setStyle("disabledSkin",CellRenderer_disabledSkin2)
cb.setStyle("selectedDisabledSkin",CellRenderer_selectedDisabledSkin2)
cb.setStyle("selectedUpSkin",CellRenderer_selectedUpSkin2)
cb.setStyle("selectedDownSkin",CellRenderer_selectedDownSkin2)
cb.setStyle("selectedOverSkin",CellRenderer_selectedOverSkin2)
but it gives error........
TypeError: Error #2007: Parameter child must be non-null.

When u click on combobox to open it up. The Component Assets of datagrid and combobox are the same so I am not able to apply different skin pattern of this two different component ..
Still is there any way pls let me ..

Problem with selectedItem (DataGrid) when dataProvider is XML

I have a problem.
I want to load my DataGrid with data from XML returned via
Struts. I have set up a test environment for the time being and I
can LOAD the data into the grid just fine, but when I want to refer
to it after it is loaded (with selectedItem) I am having all sorts
of problems. Namely, I can't access any of the data in
selectedItem. I can't even seem to make it show up in a string...
the only way I can access values is individually using :
selectedItem["@attribute"] which is NOT what I want to do...
can anyone tell me what I am doing wrong? Is there no way I
can convert the xml to an object (or is that even the problem)?
Here is code to show exactly what I mean:
<?xml version="1.0"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="vertical" creationComplete="doDummySearch()">
<mx:Script>
<![CDATA[
import mx.utils.ArrayUtil;

phoneNo='0343442323' />
<dummyData priority='1' dealerCode='B00-1033'

private function doDummySearch():void {
search_dg.dataProvider = dummyXML.children();
private function select():void {
var s:String = "";
s+=search_dg.selectedItem["@dealerCode"]+"\n";
s+="all data: \n";
for each (var entry:* in search_dg.selectedItem) {
s+=entry+"\n";
s+="^-why is this blank?\n";
s+="selectedItem.toString():
"+search_dg.selectedItem.toString()+" <-why is this blank?";
mx.controls.Alert.show(s, "selected data:");
]]>
</mx:Script>
<mx:DataGrid id="search_dg" />
<mx:Button label="select item" click="select()" />
</mx:Application>

Or even better, you can use the new E4X support in Flex, to
directly read from the XML
See this example
main.xml
<?xml version="1.0"?>
<mx:Application xmlns:mx="

s+="Quantity = "+search_dg.selectedItem.Quantity+"\n";
s+="Price = "+search_dg.selectedItem.Price+"\n";
s+="Value = "+search_dg.selectedItem.Value+"\n";
mx.controls.Alert.show(s, "selected data:");

Problem Array size in Windows 7

Hello All,
I have a VI that by opening in a new Laptop, it show some Arrays controls misfits (with a diferent array size), however i can´t put it right.
But when i make a EXE of this VI and if i run the EXE in another Computer, the front panel appears aligned and Ok.
I´m using the labview 2009 Sp1 with Windows 7, this vi have been created in another laptop in a older version and always with the Windows Xp, and whenever i was updated the version of labview it always appeared correct on those Laptop, until now when i changed the laptop and the Operating System to Win7.
Any help/advice is much apreciated
Thanks,
Solved!
Go to Solution.

Make sure you use the same font settings for all the controls that you want to be aligned. You might have some controls set to a specific font name and others left to the default Application font. LabVIEW substitutes the Application font for whatever the system default font is on a particular computer.
Different fonts are default and available on different Windows versions so you can certainly get into trouble here if you mix font families and names in the same UI.
If you request a specific font name and it is not available on a certain machine Windows will substitute it with a different font that it thinks looks similar but the heuristics of that substitution can sometimes go really way south of the equator and simply give crazy results.

You can add extra path information by using the -extrapath option in your

Urgent problem : array of linked list

In order to save memory I am trying to build an array of linkedlist with the following program. It compiles well but when I execute it, error occurs as follows,

Since I tried many alternatives to solve it but one of them succeed. Please kindly help me! Thanks in advance!

[snip]
2. Where you have 'myLL2.add(" "+j);' it should read
myLL2. The is probably a typo. If not, make sure
you understand why you need to change your code.
The forum posting code will muck up your code if you don't surround it in [ code] [code ] (no spaces) tags. Even if you do use the code tags, it preprocesses [ i] into <i> to avoid turning your code into italics.

Multi-part form problem (array & session help needed)

I have a multi-part form that consists of 3 pages(forms) which each save data to the session. When the final form is complete, I insert the session variables to the DB via a FINISH button.
I now want to take another step. Page 2 of this multi-part form allows users to add "items". Presently, they can add only 1 item, and move the page 3 by hitting a next button. I would like to add a "Add another item" button that goes to the page 2 form again, allowing more items to be entered. I believe I need an array/table to do this, but don't know how I might do this in the session.
Is it possible to create an array in the session? If so, how? If not, how might I approach this?
I am trying to avoid inserting to the database (a remote db) until after a "preview" page following the form.
Any ideas? Thx in advance.

The fluke 2625A I am still having problems arraying the channels and temperatures.

In the example program I canot array the channels and temperatures. All I can read is one channel at a time.

Joey,
I took a look at this instrument driver, and it appears that there is not a built-in function that allows you to read multiple channels at the same time. You will need to have multiple subVIs read channels individually, then build those values into an array of all the temperatures. This is the only way I could find to get an array of your temperatures after my cursory glance of the driver.
Good luck with your application, and have a pleasant day.

New modification problem(Array)

OK I had a previous code here a while back and it worked,.then i had to modify it to hold data,so i hit the books hard trying to figure it out.The program, Netbeans is wanting the Merch constructor to have a class of its own and i know that it is incorrect.

DataGrid Header Problem

Dear All,
I have some problem with accessing DataGrid HeaderText, When one column is visable false.
"Click on column content and the code will show col # and header name. Do the same After Hide Colun is clicked"
Please check the following code
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
    <![CDATA[
        import mx.controls.listClasses.BaseListData;
        import mx.controls.dataGridClasses.DataGridListData;
        import mx.controls.dataGridClasses.DataGridItemRenderer;
        import mx.events.ListEvent;
        import mx.controls.*;
        function grd_click(e:ListEvent):void{
                var icol:int = e.columnIndex;
                var column:DataGridColumn = DataGridColumn(grid1.columns[icol]);
                var headerTxt:String = column.headerText;
                Alert.show("Header text = " + headerTxt)
        function hideCol(index:int):void{
              var c:DataGridColumn = DataGridColumn(grid1.columns[index]);
              c.visible = false;
        var items:Array = [
            {name:"vlad",lname:"collak"},
    ]]>
</mx:Script>
    
    <mx:DataGrid x="90" y="99" itemClick="grd_click(event)" id="grid1" dataProvider="{items}">
        <mx:columns>
            <mx:DataGridColumn headerText="Column 1" dataField="name"/>
            <mx:DataGridColumn headerText="Column 2" dataField="lname"/>
        </mx:columns>
    </mx:DataGrid>
    <mx:Button x="90" y="262" label="Hide Column" click="hideCol(0)"/>

I think the column still exists even if you set its visibility to false. You could try something like this
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:local="*">
    <mx:Script>
    <![CDATA[
        import mx.controls.listClasses.BaseListData;
        import mx.controls.dataGridClasses.DataGridListData;
        import mx.controls.dataGridClasses.DataGridItemRenderer;
        import mx.events.ListEvent;
        import mx.controls.*;
        private function grd_click(e:ListEvent):void{
                var icol:int = e.columnIndex;
                var column:DataGridColumn = DataGridColumn(grid1.columns[icol]);
                var headerTxt:String = column.headerText;
                Alert.show("Header text = " + headerTxt)
        private function hideCol(index:int):void{
          if(index == 0)
              grid1.columns = [column1];
          else
              grid1.columns = [column2];
        [Bindable]private var items:Array = [
            {name:"vlad",lname:"collak"},
    ]]>
</mx:Script>
    <mx:DataGrid x="90" y="99" itemClick="grd_click(event)" id="grid1" dataProvider="{items}">
        <mx:columns>
            <mx:DataGridColumn id="column1" headerText="Column 1" dataField="name" />
            <mx:DataGridColumn id="column2" headerText="Column 2" dataField="lname"/>
        </mx:columns>
    </mx:DataGrid>
    <mx:Button x="90" y="262" label="Hide Column" click="hideCol(0)"/>
    <mx:Label x="90" y="56" text="Click on column content and the code will show col # and header name. Do the same After Hide Colun is clicked" width="642" height="35"/>

DataGrid Refreshing Problem

Hi All,
First let me explain my problem clearly.I am facing the
problem with refreshing datagrid for add,update,delete operations.
For adding task(todo app) i am using another mxml
component(PopUpwindow).when i do add,delete or update, changes are
happening
in database pakka and fine.There is no error in that.Only
problem is when i add or delete or update a task, datagrid has to
get refresh with the updated or new data.Then only from ui
user will know that he added a task or deleted a task etc right.
sometimes it's refreshing fine and sometimes not.If it
doesn't refresh at all times i can think of my logic.But if it's
happening sometimes and sometimes not.
after add or delete or update am using below 5 lines of code
to refresh datagrid.
getList.send(); //sending request again to load new data
using httpservice.
datagrid.dataProvider = resultList; //resultList is
bindabale ArrayCollection variable.
resultList.refresh(); //this line not all giving any
changes.i think it's not working
datagrid.validateDisplayList();
datagrid.validateNow();
Thnaks & Regards,
premadas.

Hey harsha,
the following code i'm using for deleting a task.
<mx:HTTPService id="getTodo" url="
http://dev.edinc.in:8080/poc/ToDo/GetToDo.jsp"
result="resultHandler(event)"/>
private function delTask():void
delTodo.cancel();
delTodo.send(delData);
getTodo.send();
deltaskname.text = "";
deltaskdate.selectedDate = new Date();
deltaskcategory.selectedIndex = -1;
deltaskpriority.selectedIndex = -1;
deltaskstatus.selectedIndex = -1;
Anything i need to apply here.
Thanks & Regards,
Premdas.
