<MasterTableView DataKeyNames="TaskNo" AllowMultiColumnSorting="true">

<CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings>

I have RadAjaxManager :

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="TasksAssignedGrid">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="TasksAssignedGrid" />
