Workaround for the NextPrevAndNumeric mode is to set the AssociatedControlID of the label protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) { if (e.Item is GridPagerItem) { GridPagerItem pager = e.Item as GridPagerItem; Label lbl = pager.FindControl("ChangePageSizeLabel") as Label; Panel pnl = lbl.Parent as Panel; RadComboBox combo = pnl.FindControl("PageSizeComboBox") as RadComboBox; lbl.AssociatedControlID = combo.ID; } } <telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AllowSorting="True" AllowPaging="True" GridLines="None" Width="100%" OnItemDataBound="RadGrid1_ItemDataBound"> <PagerStyle Mode="NextPrevAndNumeric" Position="TopAndBottom" PageSizeControlType="RadComboBox"></PagerStyle> </telerik:RadGrid> <asp:SqlDataSource ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" ProviderName="System.Data.SqlClient" SelectCommand="SELECT CustomerID, CompanyName, ContactName, ContactTitle, Address, PostalCode FROM Customers" runat="server"></asp:SqlDataSource>
