I have a grid

<telerik:RadGrid ID="RadGrid1" runat="server" Skin="Office2007" AllowPaging="true"

AllowCustomPaging="true" PageSize="20" AutoGenerateColumns="False" GridLines="None"

AlternatingItemStyle-BackColor="#eeeeee" ShowStatusBar="true" AllowFilteringByColumn="true"

AllowSorting="true" EnableLinqExpressions="true" OnPreRender="RadGrid1_PreRender"

OnItemDataBound="RadGrid1_ItemDataBound" OnNeedDataSource="RadGrid1_NeedDataSource">

<AlternatingItemStyle BackColor="#EEEEEE"></AlternatingItemStyle>

<MasterTableView DataKeyNames="TaskID">

<AlternatingItemStyle BackColor="#EEEEEE"></AlternatingItemStyle>

<RowIndicatorColumn>

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<Columns>

<telerik:GridTemplateColumn SortExpression="StatusCodeTypeName" DataField="StatusCodeTypeName"

HeaderText="Status" UniqueName="StatusCodeTypeName">

<ItemTemplate>

<telerik:RadComboBox runat="server" ID="DropDownList1" EnableViewState="false" DataTextField="StatusCodeTypeName"

DataValueField="StatusCodeTypeID" DataSourceID="SqlDataSource1" OnClientSelectedIndexChanged="UpdateTask"

Skin="Office2007">

</telerik:RadComboBox>

</ItemTemplate>

<FilterTemplate>

<telerik:RadComboBox ID="rcbStatus" DataTextField="StatusCodeTypeName" DataValueField="StatusCodeTypeName"

AppendDataBoundItems="true" Width="150px" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("StatusCodeTypeName").CurrentFilterValue %>'

runat="server" OnClientSelectedIndexChanged="ClientNameIndexChanged" Skin="Office2007">

</telerik:RadComboBox>

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

<script type="text/javascript">

function ClientNameIndexChanged(sender, args) {

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

if (args.get_item().get_value() == "0") {

tableView.filter("StatusCodeTypeName", args.get_item().get_value(), "NoFilter");

}

else {

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

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

<ItemStyle VerticalAlign="Top" />

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

In the Grid you can see it has a GridTemplateColumn, in which is a RadComboBox for both the ItemTemplate and FilterTemplate. The Filter template is working fine. The porblem is in the grid it shows the item radcombobox loaded with all the selections but the current value is not the selected when in the grid. How do I set the selected value?
