Hi,

I am trying to set the position of Filter textbox in my grid by javascript. On first keypress in filter textbox everything works fine, but from second time onwards i am getting an error htmlfile: Could not complete the operation due to error 800a025e.

My Code is:
Grid

<telerik:RadGrid ID="RadGridSpeciality" runat="server" CellSpacing="0" GridLines="None"
    AllowFilteringByColumn="true" EnableLinqExpressions="true">

Hi

May be problem in ajax. Try execute your code without ajax. You can also see here:
