I'm trying to do something similar to what is demonstrated here and am really stuck on a problem I am currently having and hoping someone can help. Basically, in the ObjectDataSource1_Selecting method I am checking the FilterExpression (with linq expressions set to false) and the expression is missing the UniqueName of the column that I am passing to the javascript filter() function. It looks like: "([] = 'Critical')". when I select "Critical" from the radcombo.

I've looked over it a bunch and am having trouble finding something configured wrong, here is the relevant code:

<telerik:GridTemplateColumn DataType="System.String"

FilterControlAltText="Filter Urgency column" HeaderText="Urgency" AllowFiltering="true"

SortExpression="Urgency" UniqueName="Urgency" Visible="true">

<FilterTemplate>

<telerik:RadComboBox ID="comboUrgencyFilter" DataSourceID="UrgencyTypeDataSource" DataTextField="Name"

DataValueField="Name" AppendDataBoundItems="true" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("Urgency").CurrentFilterValue %>'

runat="server" OnClientSelectedIndexChanged="UrgencyIndexChanged" Width="90px">

<Items>

<telerik:RadComboBoxItem Text="All" />

</Items>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function UrgencyIndexChanged(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter("Urgency", args.get_item().get_value(), 5);

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

<ItemTemplate>

<%# Eval( "UrgencyType.Name") %>

</ItemTemplate>

</telerik:GridTemplateColumn>

Thanks for any help
