The grid is displayed fine the first time, but then when I click on the next page button I get a JScript error: "Microsoft JScript runtime error: 'this._postBackSettings.async' is null or not an object" which seems to possibly be caused by an unwanted post back?
The MS GridView works as expected in this setup, paging through the data keeping the popup control open, not causing a full postback.
The setup is fairly simple:
<form id="form1" runat="server">
<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</cc1:ToolkitScriptManager>
<div>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"></asp:ObjectDataSource>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True" GridLines="None" onneeddatasource="RadGrid1_NeedDataSource" PageSize="5" >
</telerik:RadGrid>
</ContentTemplate>
</asp:UpdatePanel>
<cc1:PopupControlExtender ID="PopupControlExtender1" runat="server" TargetControlID="TextBox1" PopupControlID="RadGrid1">
</cc1:PopupControlExtender>
</div>
</form>
Thanks.
