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

I'm turning to you folks for answers because this really blows my mind... Let me explain:I'm using a slightly modified spark NumericStepper as an item editor in a datagrid. I had to modify the original because for some reason it's values only went up to 10.So i extended NumericStepper like so:

I've a custom itemRenderer for my datagrid. To set the actual data I use the following method:

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 :: Creating Multiple ItemRenderer For DataGrid Column

Aug 25, 2009

I actually wanted to create an itemrenderer which will contain below code :
<mx:HBox xmlns:mx="[URL]" width="0" height="0" >
<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?

Flex :: Validate Certain DataGrid Rows Made With ItemRenderer?

In this DataGrid column, I require number validation on only the data with the type="NUMBER" field set.

What is the best way to validate only the rows with the type="NUMBER" field set?

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?
