Hi Team, Please go through the ticket. http://www.telerik.com/account/support-tickets/view-ticket.aspx?threadid=821301 Here' there is javascript error on Filter click. We have attached the example in first thread. The example contains a grid with a runtime header column addition. When the filters are on with Grid, clicking any of the filter icon to open "filter menu" causes a JavaScript error. If we skip the code to add "Runtime header column", there is no such error. But there is requirement of our client to have such header "Skip to Content" button in the header above filter. Please see, - We are using a webcontrol, AECTelerikGrid as attached. - This should display "Skip to Content" in the header bar. - After this, click on any of the filters and this will result in JS error as attached. Thanks, Sunil
