Hello,
I am trying to filter a column in a radgrid with a custom filter template, based on the id´s of the objects and not the display names (in some cases we have entries with the name / display name)

My Code is:

<telerik:GridBoundColumn AllowFiltering="true" AllowSorting="true" DataField="Accountrole.Name"

HeaderText="<%$ Resources:Administration,Role %>" UniqueName="Accountrole.RoleId">

<FilterTemplate>

<telerik:RadComboBox ID="RadComboBoxRole" DataSourceID="RoleDataSource" DataTextField="Name"

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

runat="server" OnClientSelectedIndexChanged="RoleIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="<%$ Resources:Basic,All %>" />

</Items>

</telerik:RadComboBox>

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

<script type="text/javascript">

function RoleIndexChanged(sender, args) {

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

tableView.filter("Accountrole.RoleId", args.get_item().get_value(), "EqualTo");

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridBoundColumn>

Unfortunately the filtering does not work because my entity data source get athe following filterexpression from the grid (seen in debug mode):
RadGrid1.MasterTableView.FilterExpression = "(it.Accountrole.Name = \"1\")"
but it should be:
RadGrid1.MasterTableView.FilterExpression = "(it.Accountrole.RoleId= \"1\")"

How can I tell the Grid to generate the correct filter expression?

Thanks in advance!
