I am a user control that has a radio button and I am trying to ajaxyfy the radio button from the main aspx page. The code is as followed:

Control MyControl = (Control)Page.FindControl("WebUserControl1");

RadioButton MyButton = (RadioButton)MyControl.FindControl("rdbFirstOne");
Label MyLabel = (Label)MyControl.FindControl("Label1");

RadAjaxManagerProxy1.AjaxSettings.AddAjaxSetting(MyButton, MyLabel, null);

When I debug this, I get object reference error on "RadioButton MyButton = (RadioButton)MyControl.FindControl("rdbFirstOne");
"
line.


Please help. Thanks. 

Hello Shamim,

The provided code looks correct.  Could you please elaborate on which event are you adding the Ajax settings? Also you can try to initiate ajax request explicitly from the WebUserControl by using  RadAjaxManager.GetCurrent() method call and see if the issue still persists. More information on this implementation could be find here.

Kind regards,
