Question

I developed a server control which is custom control inheriting from checkboxlist and implements the IScriptControl i use the controls id, clientId to set some properties used for rendering in client during the controls constructor but gosh both are null when i debugged them. So there should be something wrong , what is it?

Answer 1

It is during the Pre_Render stage that you can get the actual clientID and ID properties

public override void Pre_Render()
{

//control.ClientID and control.ID are available now

}
