User Control Issue

[Aditya]

Hi,
I have a RadTree in User Control A & RadioButtonList in another User Control B under my main aspx page. When I check a node in RadTree in User Control A., I want to get selected index of RadioButtonList 
in User Control B. How i'm i supposed to get the output.??

Regards,
Aditya

Hello Aditya,

Try the following code to achieve your scenario.
C#:

protected void Radtreeview1_NodeClick(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
{
  UserControl ctrl = (UserControl)Page.FindControl("WebUserControlB");
  RadioButtonList list = (RadioButtonList)ctrl.FindControl("RadioButtonList1");
  string value=list.SelectedIndex.ToString();
}

Thanks,
Princy.

Hi,
  UserControl ctrl = (UserControl)Page.FindControl("~/UserControls/NewOnlineTemp.ascx");
The above code doesn't work. I get a null value.

Hello Aditya,

One way I can think of is that you use either client-side or server side of the RadTreeView events (Server-Side Events or Client-Side Events) and find the user control and then the corresponding control (here is more information how to achieve this on the server). In case this does not help I would recommend that you open a support ticket and send me a simple runnable page that I can inspect locally and help you out in the particular scenario. 

Kind regards,
