Hi,
I'm having Microsoft JScript runtime error: Unable to get value of the property 'PageRequestManager': object is null or undefined when ever page is loaded. I can no longer clicked on the dropdown whenever I continue with the page.
It throws error on this line on Telerik.Web.UI.We.....[dynamic] -->
window[Sys.WebForms.PageRequestManager.getInstance()._uniqueIDToClientID(this._uniqueID)]=this;
