Hi Team ,
I have created webpart where i have included RadScript manager as below . Webpart is displaying correctly where as when I take mouse over any item on left navigation bar i get error as "A runtime error has occured .Do you wish to Debug?" and when I debug the error control takes me over to "onmouseover="Menu_HoverStatic(this)" ,Can you suggest as how to go about the issue .
_scriptManagerTree = ScriptManager.GetCurrent(this.Page);
if (_scriptManagerTree == null)
