I have a  RadGrid and code behind and I'm trying to filter on a column.  I am also following the basic example under live examples (except am using NeedDataSource instead of using a SqlDataSource in my code).  When I hit enter in a filter I get the AJAX loading circle but nothing is ever filtered.  Can anyone tell me what I'm doing wrong?  I believe I am following the example correctly:

Code Behind:
 protected override void OnInit(EventArgs e)
 {
this.RadGridItems.NeedDataSource += new Telerik.Web.UI.GridNeedDataSourceEventHandler(RadGridItems_NeedDataSource);
        base.OnInit(e);
}

void RadGridItems_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
this.RadGridItems.DataSource = Item.ListItems(); /* My object which is being bound and displayed correctly in the radgrid */
}

ASP.NET Code (I've slimmed the example to just one GridBoundColumn--all data is displayed correctly):
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadGridItems">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridItems" LoadingPanelID="RadAjaxLoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" />

<telerik:RadGrid ID="RadGridItems" runat="server" GridLines="None" AllowPaging="True" CssClass="RadGrid" PageSize="20"
        AllowSorting="True" AutoGenerateColumns="False" ShowStatusBar="true" AllowMultiRowSelection="false" AllowFilteringByColumn="True">
        <MasterTableView Width="100%" CommandItemDisplay="Top" DataKeyNames="Id" AllowFilteringByColumn="True">
            <Columns>
                <telerik:GridEditCommandColumn UniqueName="EditCommandColumn"  />
                <telerik:GridBoundColumn UniqueName="CatalogNumber" HeaderText="Catalog Number" DataField="CatalogNumber" HeaderStyle-Width="20%" 
                     CurrentFilterFunction="EqualTo" FilterDelay="4000" ShowFilterIcon="false" SortExpression="CatalogNumber" />
            </Columns>
        </MasterTableView>
</telerik:RadGrid>

This code properly shows the radgrid control and populates it with data.  When I type text into the filter box, the AJAX loading panel shows but nothing is ever filtered.

I'd really appreciate some help as to what I'm doing wrong.

Thanks,

Ken

Hello Kenneth,

I tried to replicate the issue in a project closely following your code but to no avail. You can find it attached to this post, could you please view it and let me know if I am missing anything out?

Thanks for the help.  After much hair-pulling (and I apologize this was not in the example--didn't think it would have an impact), I found what was preventing the filtering from working.

<ClientSettings><ClientEvents OnRowDblClick="jsfunction" /></ClientSettings>

That following portion would make the filtering not work.  I since removed it since filtering was more important to me than being able to double click on a column for editing.

Thanks,

Ken
