Flex :: Put An Itemrenderer On The DataGrid Itself Rather Than A Datagridcolumn?

Jul 8, 2009

Is it possible to put an itemrenderer on the DataGrid itself rather than a datagridcolumn? I could only find examples for datagridcolumn. I want a generic itemrenderer on all the items in a datagrid...

Flex :: Datagrid - Get The DataGridColumn's DataField In Its ItemRenderer?

Aug 20, 2010

I'm trying to reach the dataField of a DataGridColumn in the itemRenderer. Below is the dataGrid:

[Bindable] public var weeksOfMoth:ArrayCollection = new ArrayCollection([

In the set data function of the itemRenderer, I receive an entire week (which is ok), but the itemRenderer doesn't know which day to use because the dataField is unknown. Does anyone know how to reach this dataField in the itemRenderer?

Flex :: Datagrid - Display Tooltips When Using A DataGridColumn ItemRenderer?

Oct 11, 2011

On my flex (flash builder 4) DataGrid - DataGridColumn , I have set a custom itemRenderer

itemRenderer="myComponents.EncounterDGItemRenderer".

My renderer is a Label

public class EncounterDGItemRenderer extends Label

I found that my tooltips (datatips) stopped working once I started using this custom renderer. I also found that I can set the tooltip on the label in the

override protected function updateDisplayList

by setting:

toolTip=data['addedDate'];

This works find, however the problem is I need to choose a different data field based on the column. I was hoping for something similar to how a DataGridColumn labelFunction works - where I have access to "column.headerText" or "column.dataField". However I only have access to the underlying data object, not the name of what is being displayed (unless I am missing something).

Is there a way in a data grid item renderer to know what the column header text is, or do you have a different approach?

Flex :: Data Passed From DataGridColumn.itemToLabel To DataGrid.itemRenderer.set(data)?

Dec 4, 2009

I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.

I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).

Flex :: RadioButton In Custom DataGridColumn ItemRenderer In AS3

Apr 30, 2010

I have a datagrid that I want to add a column of radio button using AS3 (instead of mxml). I was able to do this with a custom itemRenderer.
var dgc:DataGridColumn = new DataGridColumn();
dgc.itemRenderer = new ClassFactory(com.mypackage.RadioBtnColumnItemRenderer);

In my RadioBtnColumnItemRenderer.mxml, I have a box with a radioButton... like so:
<?xml version="1.0" encoding="utf-8"?>
<mx:Box xmlns:mx="[URL]" horizontalAlign="center" verticalAlign="middle">
<mx:RadioButton id="btnRadio" groupName="btnRadioSelect"/>
</mx:Box>

When I run the application, the radio button shows up in the column as it should. However, I cannot select just ONE of the radio buttons. I am able to select all of them, but I don't want this... I want the ability to select one and then if I select another one, then the first one is unselected and the current one becomes selected (just like you would expect radio buttons to work).

Flex :: Improve Datagrid Performance When Using Itemrenderer With In Datagrid?

Jul 31, 2009

For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

Flex :: Datagrid With RadioButtonGroup Itemrenderer

Aug 12, 2009

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?

It is ment for dynamic questionnaires.

Flex :: Create New Instance Of Itemrenderer In MX DataGrid?

May 12, 2011

I want to create new instance of item renderer for my data grid.

A single instance of your Item Renderer class (ListIR) is created for each visible item of the list-based control.

As the user scrolls through the items of a data grid control, Item Renderer instances are recycled rather than creating new instances.

But i would like to create new instance ..while scrollling item in datagrid.

Flex :: Datagrid - ItemRenderer Flex Values Getting Not Rendered According To ArrayCollection Provider?

Flex :: Creating Multiple ItemRenderer For DataGrid Column

Aug 25, 2009

I actually wanted to create an itemrenderer which will contain below code :

<mx:Label text="{data.xval}" />
<mx:Spacer width="100%" />
<mx:Image source="edit.gif" width="16" toolTip="Edit" />
</mx:HBox>

Now when I click on the image datgrid column should be editable, for that I am using a textinput as an itemeditor. Now I also want to highlight all those cell for this datagrid column which are having data more than 8 characters. I am able to do this separately using 2 different itemrenderers. But I want to get this all together. Can we have multiple itemrenderer for any datagrid column?
