Hi,

I was not able to understand completely the issue you are asking about. You have posted it in a forum thread about RadDock for ASP.NET AJAX. Could you please provide more details what is the connection of the custom control you are creating with the Telerik's RadDock control? Please, give us more information about your issue so that we can get a better idea of what you are trying to achieve.

Best regards,

Hi,
I  have created a custom control with two labels and two Radcomboboxes. The custom control  gets postback. I want to avoid the postback  for the whole control.
so i tried using the Rad ajax panel. I am not sure how to render the Rad Ajax Panel to the custom control. please help me in this process.....

Dock controol concept will not help me......

Thx....

Hello Ragupathi,

Basically, if you create RadAjaxPanel instance, add the comboboxes to it and then add the ajax panel to the Controls collection of your custom control, you should be done. Thus the dropdowns should trigger ajax requests instead of plain postback when you change the selected item.
