Issue with AutoPostBack RadComboBox inside RadGrid GridTemplateColumn

I'm trying to add a AutoPostBack enabled RadComboBox to the ItemTemplate of a RadGrid's GridTemplateColumn. The RadComboBox relies on certain row data so I'm creating it dynamically using the grid's ItemDataBound event:

protected void rgFaqs_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item.ItemType == Telerik.Web.UI.GridItemType.Item || e.Item.ItemType == Telerik.Web.UI.GridItemType.AlternatingItem)

{

FaqListItem item = (FaqListItem)e.Item.DataItem;

if (item == null)

return;

WorkflowComboBox workflowBox = new WorkflowComboBox();

workflowBox.ItemID = item.Id;

workflowBox.DataBind();

PlaceHolder phWorkflowBox = (PlaceHolder)e.Item.FindControl("phWorkflowBox");

phWorkflowBox.Controls.Add(workflowBox);

}

Here is a snippet of my custom overridden WorkflowComboBox:

public class WorkflowComboBox : Telerik.Web.UI.RadComboBox

{

public int ItemID { get; set; }

public WorkflowComboBox()

{

AutoPostBack = true;

}

protected override void OnInit(EventArgs e)

{

this.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(WorkflowComboBox_SelectedIndexChanged);

EnsureChildControls();

base.OnInit(e);

}

Like I said, this works perfectly fine on the initial page load. The problem occurs on the AutoPostBack of the ComboBox. This causes a postback which doesn't appear to be firing the ItemDataBound event again. That in turn causes my the Combobox field to not be loaded properly.

I've also tried moving the ItemDataBound stuff to the RadGrid's ItemCreated event instead. Everything works fine on first page load. When the ComboBox AutoPostBack gets fired though, the e.Item.DataItem is null.

I'm getting the vibe that this is an issue/conflict? with the event sequence of the RadGrid and the RadComboBox. It also appears during this whole process that the RadComboBox SelectedIndexChanged event is never being reached.

Any thoughts? Am I missing something!?

-Thanks

xml ToolsFile with Paths?

hi I have a set of RadEditors. I use a server side method to assign different xml ToolsFile to different RadEditors.
Is it possible that I can specify paths in the same xml? e.g.

<root>
<tools name="MainToolbar" dockable="true" enabled="true">
<tool name="Bold" />
<tool name="Italic" />
<tool name="Underline" />
<tool separator="true"/>
<tool name="InsertOrderedList" />
<tool name="InsertUnorderedList" />
<tool name="ImageManager" ViewPaths="~/Images" UploadPaths="~/Images/New" DeletePaths="~/Images/New/blah" />
<tool name="DocumentManager" ViewPaths="~/Docs" UploadPaths="~/Docs/New" DeletePaths="~/Docs/New/blah"/>
</tools>
</root>

thanks in advance

Load On Demand functionality not Loading on Demand.

Hi everyone, I'm working with the RadRotator and have followed the LoadOnDemand example to set up a functional rotator control that we could use on our web site. I see that the backend code of the web service is returning viewable images when viewed through an image visualizer in the VS2010 debugger. But after returning the an array of RadRotatorItemData I get the error message:

RadRotator items request failed : Exception=Object reference not set to an instance of an object.

Any idea what might be going wrong?

Also let me know if showing code would be helpful in getting to the bottom of this issue.

Thanks for your help!
