Hi Arun,

Please have a look into the following sample code snippet which works fine at my end. Please provide your code if it doesn't help.

ASPX:

<telerik:RadGrid ID="radgrdOrders" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="false" AllowPaging="true" AllowFilteringByColumn="true">
    <MasterTableView>
        <Columns>
            <telerik:GridTemplateColumn>
                <FilterTemplate>
                    <telerik:RadComboBox ID="RadComboBoxTitle" DataSourceID="SqlDataSource1" runat="server"DataTextField="CustomerID" DataValueField="CustomerID" Height="200px" AppendDataBoundItems="true" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("CustomerID").CurrentFilterValue %>'
                       OnClientSelectedIndexChanged="TitleIndexChanged">
                        <Items>
                            <telerik:RadComboBoxItem Text="All" />
                        </Items>
                    </telerik:RadComboBox>
                    <telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
                        <script type="text/javascript">
                            function TitleIndexChanged(sender, args) {
                                var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
                                tableView.filter("CustomerID", args.get_item().get_value(), "EqualTo");
                            }
                        </script>
                    </telerik:RadScriptBlock>
                </FilterTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridBoundColumn DataField="OrderID" UniqueName="OrderID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="CustomerID" UniqueName="CustomerID">
            </telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Thanks,
Shinu.
