<telerik:RadPanelBar ID="RadPanelBar1" runat="server">

                </Items> 
            </telerik:RadPanelItem> 
        </Items>  
 </telerik:RadPanelBar>

This is my  .ascx.cs file:

public override void DoLayout( )
  {
     //Get collection
     TrackableCollection<ProjectActivityBooking> acitivities = existingRegistration.ProjectParticipant.ProjectEntity.ProjectActivityBooking;
     //Here it is possible to get hold of the checkbox
     CheckBox cb = RadPanelBar1.FindItemByValue("templateHolder").FindControl("CheckBox2") as CheckBox;
     //Add datasource and bind
     this.RadPanelBar1.ItemDataBound += new RadPanelBarEventHandler(itemDatabound);
     this.RadPanelBar1.DataSource = acitivities;
     this.RadPanelBar1.DataBind();
  }

The code below let me add a new instatited CheckBox, but it is not added as subitem. Instead I´m getting a "static" RadPanelBar without the nice feature of being pushed and sliding out the subitems ie. activities

void itemDatabound(Object sender, RadPanelBarEventArgs e)
  {
     //Get panelItem
     RadPanelItem item = (RadPanelItem)e.Item;
     //Create Checkbox
     CheckBox chk = new CheckBox();
     //Get Activity
     ProjectActivityBooking activity =  item.DataItem as ProjectActivityBooking;
     //Set activity name
     chk.Text = activity.ProjectActivity.ActivityName;
     //Add control
     item.Controls.Add(chk);
   }

I think the way forward is something like below, but that will not get me my CheckBox.
void itemDatabound(Object sender, RadPanelBarEventArgs e)
{
   //This will throw an exception
   //CheckBox cb1 = RadPanelBar1.FindItemByValue("templateHolder").FindControl("CheckBox2") as CheckBox;
   //This will return null as it will now find the templateHolder RadPanel item
   //How will I then get hold of the CheckBox2 when the templateholder do not find/returns null
   //RadPanelItem item = e.Item.FindControl("templateHolder") as RadPanelItem;
}

Please let me know what I´ve done wrong?

Hi, 
I am using a MOSSradEditor inside the following control hirarchy: 

Sharepoint Web part
- - - - Web user control
- - - - - - - - Rad Dock
- - - - - - - - - - - - MOSSRadEditor.

I would like to have ModeChange event of the MOSSRadEditor on the server side. For this purpose I handle the ClientModeChange event and then use RadAjaxManager to send the ajaxrequest to the server. But the method $find returns null in the line: 

Therefore I receive the javascript error Error: 'null' is null or not an object on the next line:        

Can you pleae let me know how I can solve this problem, 
or proposing any pther way to have ModeChange event on the server side?
Here is the code section.
