Dynamic comboBox in a dataGrid?

i have a dataGrid that starts out blank. When a button is
clicked, it populates based on the contents of a few components.
The 3rd column needs a comboBox. I need the following
behaviors:
1-when the button is clicked, this populates with the text
values in a certain text field.
2-under certain circumstances, i need to be able to add and
subtract from this comboBox.
i have read this:
http://blog.flexmonkeypatches.com/2008/02/18/simple-datagrid-combobox-as-item-editor-examp le/
but it looks like the comboBox in that example has fixed
values. How can i dynamically alter the values in
these comboBoxes? i have the comboBoxes in the dataGrid
component, but i can't figure out how to access their
dataProviders!
thanks!

You can have your comboBox itemRenderer populate based on an
ArrayCollection in your dataDrid dataProvider. Then, by changing
the dataProvider's ArrayCollection field, you could change each of
the comboBoxes accordingly. If you need different comboBox values
for different comboBoxes, then you will need something a bit
different. It would help to see your code.

Hi,
I think you need to declared your array public at the
begining of the page
like
[Bindable]
public var dataArray = new ArrayCollection();
You need to use outerDocument.
<mx:ComboBox activate="true" labelField="TEXT"
dataProvider="{outerDocument.dataArray}" />
I discover that the components are case sensitive also.
I hope this help.

Hi,
I want to embedded a ComboBox in a Datagrid.

_data = value;
var dp:DataProvider = new DataProvider(value.plaats);
dataProvider = dp;

-How can I transmit the ComboBox.selectedItem to the Datagrid
-and how can I read the CellRenderer.data in the DataGrid,

Datagrid.itemToCellRenderer(e.item) as ComboBoxCellRenderer
=>returns null

DataGrid with dynamic comboboxes

I need to design a dataGrid with comboboxes in one column. These comboboxes should all have different dataProviders based on a value from column 1. What would a general approach be?
Thanks

The renderer's data property is the data for the entire row so you can get the column1 data and assign the combobox's dataprovider accordingly.

WPF Finding Selected ComboBox Item Within DataGrid

Hi all... I'm having an issue trying to access the selected item value in a ComboBox within a DataGridTemplateColumn.
Through another question/answer I have got the ComboBox displaying the names as it should but the next step I'm having issues with is to be able to loop through each row in the DataGrid and determine the selected value of the ComboBox in that row as
well as some other items and run some other code based on those values.
Any help would be appreciated.

In a way, wpf is similar to web.
More so than windows forms anyhow.
XAML is mark up and flows like html.
You have padding and margin which are rather familiar concepts.
Whereas windows forms is absolute positioning and... well totally different from markup.
You might find this sample interesting as a sort of mvvm taster.
https://gallery.technet.microsoft.com/WPF-Dialler-simulator-d782db17
and event handling equivalents
http://social.technet.microsoft.com/wiki/contents/articles/30564.wpf-uneventful-mvvm.aspx
Note
With a combo you bind the selecteditem to a propfull and then you can put a method call in the setter. That will then be invoked when the user changes selection.
Good luck and welcome to wpf development.
It's a great technology.
Hope that helps.

Venktesan,
You are trying compare String and int..! which is not possible try to case the txtIn.text to int using parseInt(txtIn.text).
ORIGINAL:
if(txtIn.text != ADD_TASK).---->error : Comparison between a value with static type String and a possibly unrelated type int
                    tasks.addItemAt(new Task(txtIn.text, 0, ""), e.rowIndex);----> error:Implicit coercion of a value of type String to an unrelated type int.
EDITED:
if(parseInt(txtIn.text) != ADD_TASK).---->error : Comparison between a value with static type String and a possibly unrelated type int
                    tasks.addItemAt(new Task(parseInt(txtIn.text), 0, ""), e.rowIndex);----> error:Implicit coercion of a value of type String to an unrelated type int.

How to use combobox to filter datagrid in Flash Builder 4?

Hi,
I've been working through the TestDrive application with Flash Builder 4 and I would like to learn how to filter a datagrid using a combobox. I've googled the subject and results for many different versions of Flash, some which look like they will take a considerable amount of time to implement. I'm hoping with Flash Builder 4 there is a straight-forward way to do this without writing pages of code.
I think I may be close to getting this working by passing the combobox value into a PHP script which queries the database with a WHERE clause.
Thakns,
David

I was able to get the data returned from a PHP call into an array by placing the following in the service result handler:
   public var myEmployeesArray : Array;
   [Bindable]
   public var myEmployeesDataProvider : ArrayCollection;
    myEmployeesArray = mx.utils.ArrayUtil.toArray(event.result);
    myEmployeesDataProvider = myEmployeesArray[0];   //data provider for the datagrid
Not certain how to use filterfunction yet though. I started to read this page but need to work on it more: http://cookbooks.adobe.com/post_Using_the_to_ArrayCollection_s_filterFunction-5441.html
I'd like to filter only one field in the ArrayCollection.
Also, for anyone else who may be learning while reading this, I found the following page helpful in figuring out how to load the PHP service return data into an array:

Attach Dynamic ComboBox

Hi dear,
I am still working with Jdev9i and need to attach a dynamic combo box to the grid in applet. i found an oracle class called StaticGridComboBox(), but this good only for a static combo. Is there a class/method to attach a dynamic combo to the grid? or any work around?
Thanks

Frank,
I meant a combobox that could be bound to a table.
Thanks.

Database driven combobox itemrenderer in DataGrid

Hi
I created a database driven combobox itemrenderer, code see below:
The data is loaded and shown correctly, but when I change the combobox, suddenly a "0" appears:
I can see in the debugger in combobox1_changeHandler, that the correct data is taken from the combo "this.selectedItem.data=3;" and written to "data.professionGroup", (changed from "1" to "3")
but then when the code jumps to set data the "value.professionGroup" is "0"?!?!
Thank yor for any pointers!

and here is the implementation:

var col:GridColumn = GridColumn(personnel.columns.getItemAt(0));
col.itemRenderer = PersonnelPerson;
Please help.
Thanks

Actually, after adding the following code it started working:
import spark.skins.spark.DropDownListSkin;
override public function stylesInitialized():void
      super.stylesInitialized();
      this.setStyle("skinClass", DropDownListSkin);

Thanks in advance

The error message indicates the problem fairly clearly. _feed_list is defined as a ComboBox in your first line of code. You are passing that as an argument in your populate(_feed_list) line of code. However, the populate function is expecting an XMLList object to be passed, not a ComboBox.
You probably really mean to be using...
          populate(feed_items);
since that is the only XMLList to be found

Using dynamic column name in datagrid selectedItems

Hi
I have a datagrid loaded with 2 columns. Allowmultiselect is turned on.
Based on the values selected at run time, I get the corresponding selected column name and its values and shown it on HTML screen.
// grp is datagrid
// dgrcl is a data grid column
// selflds is an array which has 0,1,2,3 values
//selflds[0] = name,selflds[1]=age
for (var l:int=0; l<grp.columnCount; l++)
dgrcl =grp.columns[l];
selflds[l] = dgrcl.dataField;
// srhVals will have only one selected value at any point
// getting the corresponding selected column name and its value
var srhVals:String;
srhVals = String(grp.selectedItem[selflds[1]]);
I am trying to achieve the above selection instead by .selectedItems somthing like this below. By doing like this, I will get all the selected items but not only one. If i try below syntax, i get error. Any one has ideas on how to do.
srhVals = String(grp.selectedItems.selflds[1]);

Hi
I got my mistake, there should be no dot operator after selectedItems;
I got a solution - it goes like this:
for(var g:int=0;g<grp.selectedItems.length;g++)
srhVals = srhVals + String(grp.selectedItems[g][selflds[1]]);
So the complete scenario is like this:
Datagrid:
Name      Age
a               20
b               30
c               40
d               50
I am selecting b,d in UI. At run time, I get programatically the selecteditem column name as "Name", loop through the selecteditems and store the value in srhVals as b,d.
b,d will be finally shown in UI.
