Hello,

i am using Telerik Version Q1 2009.

In my RadGrid is a filter like that:

 <telerik:GridTemplateColumn DataField="BETRIEBSNR" HeaderText="Betriebsnr" UniqueName="BETRIEBSNR">

            <FilterTemplate>

                <telerik:RadComboBox ID="RadComboBox1" DataSourceID="SDS_FILTER_BETRIEBSNR" DataTextField="BETRIEBSNR"

                 DataValueField="BETRIEBSNR" AppendDataBoundItems="true"

                 SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("BETRIEBSNR").CurrentFilterValue %>'

                 runat="server" OnClientSelectedIndexChanged="SelectedIndexChanged" EnableLoadOnDemand="true"

                  AllowCustomText="true" MarkFirstMatch="true">

                    <Items>

                        <telerik:RadComboBoxItem />

                    </Items>

                 </telerik:RadComboBox>

                 <telerik:RadScriptBlock ID="RadScriptsBlock1" runat="server">

                    <script type="text/javascript">

                        function SelectedIndexChanged(sender, args) {

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

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

                        }

                    </script>

                 </telerik:RadScriptBlock>

            </FilterTemplate>

            <ItemTemplate>

                <%#Eval("BETRIEBSNR")%>

            </ItemTemplate>

        </telerik:GridTemplateColumn> 

…

<asp:SqlDataSource ID="SDS_FILTER_BETRIEBSNR" runat="server"

                ConnectionString="<%$ ConnectionStrings:APPDB %>" SelectCommand="SELECT DISTINCT BETRIEBSNR FROM    BETRIEBE"></asp:SqlDataSource>

If I take an Item i’m getting this message:

Sys.WebForms.PageRequestManagerServerErrorException: Selection out of range

Parametername: value

Telerik.Web.UI.WebResource.axd Zeile:6
