Hi,

I am using RadGrid and I have defined my radcombobox inside FilterTemplate but I want to bind that control programatically in OnItemDataBound event. I have tried to find out that control using GridDataItem but I am getting nothing. I also tried to find out that control in Grid Item_Created event but still getting nothing.

After that I use sqldatasource to bind that control but when I load the radgrid, I can't see my radcombobox.

<telerik:GridTemplateColumn DataField="PortalName" HeaderText="Shop" UniqueName="PortalName"

HeaderStyle-Width="200px" SortExpression="PortalName">

<FilterTemplate>

<telerik:RadComboBox ID="rcbPortal" DataTextField="PortalName" DataValueField="PortalID" DataSourceID="SqlDataSource1"

Height="100px" AppendDataBoundItems="true" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("PortalName").CurrentFilterValue %>'

runat="server" OnClientSelectedIndexChanged="PortalIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="All" />

</Items>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock3" runat="server">

<script type="text/javascript">

function PortalIndexChanged(sender, args) {

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

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

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

<ItemTemplate>

<asp:Image ID="imgPortal" runat="server" ImageAlign="AbsBottom" />

<asp:Label ID="lblPortalName" runat="server" Text='<%# Eval("PortalID") %>'></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

Protected Sub rgOrders_ItemCreated(ByVal source As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgOrders.ItemCreated

If TypeOf e.Item Is GridFilteringItem Then

Dim rcbShop As RadComboBox = e.Item.FindControl("rcbPortal")

rcbShop.DataSource = pc.GetPortals()

End If

End Sub

Hello Muhammad,

I have tried the same and it worked as expected. Try calling dataBind() method after populating the RadComboBox. Here is the code which I tried and which worked as expected. Also please make sure that you have set AllowFilteringByColumn="true"

VB.

Protected Sub RadGrid1_ItemCreated(sender As Object, e As GridItemEventArgs)

If TypeOf e.Item Is GridFilteringItem Then

Dim item As GridFilteringItem = DirectCast(e.Item, GridFilteringItem)

Dim combo As RadComboBox = DirectCast(item.FindControl("rcbPortal"), RadComboBox)

combo.DataSource = SqlDataSource1

End If

End Sub

Thanks,
Princy.
