Hello Serban,
Yes, It is possible to have any control inside FormTemplate. Here is one sample code which places RadComboBox in FormTemplate section and populating it with SqlDataSource. You can also populate it with any DataSource by accessing it from code behind.
C#:
Also please go through the following demo for more information on FormTemplate.
Grid / Form Template Edit Form.
Thanks,
Princy.

Thankyou Princy.
Not sure how this would work with Entity Framework as the data source ID would not be filled.
I may be able to just use:
Any thoughts on using a telerik:RadComboBox with EF datasource inside a FormTemplate?

Hello Serban,
You can achieve this by accessing the RadComboBox inside FormTemplate from code behind and set its DatSource property from there. Sample code is given below.

It is working fine. But my question how do we bind to a field in the radgrid
from code behind
protected void RadGrid_SC_D_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridEditFormItem && e.Item.IsInEditMode)//editform
{
GridEditFormItem editItem = (GridEditFormItem)e.Item;
RadComboBox rdcombo = (RadComboBox)editItem.FindControl("RadComboBoxSpClass");
DataTable mdSpClass = Database.Load("SELECT [spon_class_id], [spon_class_name] FROM [grant_code_spon_class] WHERE spon_class_ser='" + DDL_SLS_D.SelectedItem.Text.Trim() + "'", "spclass");
rdcombo.DataSource = mdSpClass;
rdcombo.DataTextField ="spon_class_name";
rdcombo.DataValueField = "spon_class_id";
rdcombo.DataBind();
}
}
From the above code, when I click a row for edit in RadGrid, my ComboBox was showing exacltly what I wanted to see. But it is not bound to a field in the radgrid.
From the below code, you could see that with a RadCombobox when the datasource is specified in the control, I am able to bind the field in the telerik RagGrid. But how do I acheive that with Telerik ComboBox, where my datasource I have done with code behind. I had to comment that one to see atleast it is working
<telerik:RadComboBox runat="server" ID="RadComboBoxSpClass" DataTextField="spon_class_name" Height="300"
DataValueField="spon_class_id" DataSourceID="SPClassDataSource" SelectedValue='<%#Bind("dmn_spons_class_id") %>' Width="250">
</telerik:RadComboBox>
<asp:SqlDataSource ID="SPClassDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:strCnnNovaDev %>"
SelectCommand="SELECT [spon_class_id], [spon_class_name] FROM [grant_code_spon_class] ">
</asp:SqlDataSource>
<%--<telerik:RadComboBox runat="server" ID="RadComboBoxSpClass" AutoPostBack="true" Width="250" Height="300" >
</telerik:RadComboBox>--%>

Hi Sarada,
I guess you want to bind your RadComboBox in view mode from code behind. Please try the following code snippet:
