I'm having trouble getting to the RadioButtonList control that is added dynamically when the page loads.
Here's a snippet of code that creates a RadPanelItem, add a RadioButtonList control to it, and then adds that to the RadPanelBar:

Dim

 

rdiobtnList As New RadioButtonList

 

rdiobtnList.ID =

"AssignmentRadioBtnList"

 

 

For Each Assignmentsdr As DataRow In AssignmentsDataSet.Tables(0).Rows

 

RowCount += 1

 

Dim li As New ListItem

 

li.Value = Assignmentsdr.Item(

"AssignmentListID")

 

li.Text = Assignmentsdr.Item(

"Assignment")

 

li.Selected =

False

 

rdiobtnList.Items.Add(li)

 

Next

 

 

Dim AssignmentPanelItem As New RadPanelItem

 

AssignmentPanelItem.Value =

"Assignments"

 

AssignmentPanelItem.Controls.Add(rdiobtnList)

AssignmentsRadPanelBar.Items.Add(AssignmentPanelItem)

 

Here is how I have the ASPX page setup:

 

 

<telerik:RadPanelBar ID="AssignmentsRadPanelBar" Runat="server" Skin="Web20" Width="150px">

 

 

 

    <CollapseAnimation Duration="100" Type="Linear" />

 

 

 

    <ExpandAnimation Duration="100" Type="Linear" />

 

 

 

</telerik:RadPanelBar>

I've looked through the FAQ's and the Tutorials, but none of the tutorials touch on adding RADPanelItems dynamically.

Any help would be very much appreciated.

Hello Christopher,

Try the following code snippet for accessing the RadioButtonList placed in RadPanelItem.

CS:
 
protected void Button1_Click(object sender, EventArgs e) 
    RadPanelItem item = AssignmentsRadPanelBar.Items[0]; 
    RadioButtonList rdiobtnList1 = (RadioButtonList) item.FindControl("AssignmentRadioBtnList");

Thanks Shinu.
However, the rdiobtnList1 is empty (nothing).  The code definitely accesses the RadioButtonList I added to the PanelItem, but there isn't anything there.  I don't understand.  Also, when the page loads, the radio buttons themselves show on the screen but not the text associated with them?

Any ideas?
