Hello Ranganath,

 You can check out the following code snippet for binding a RadComboBox in the FormTemplate of RadGrid.

ASPX:

 <EditFormSettings EditFormType="Template">
           <FormTemplate>
           <table id="Table1" width="300">
           <tr >
           <td colspan="30" >
           </td>
           <td colspan="30">
           </td>
           <td>
            <telerik:RadComboBox ID="RadComboBox1" runat="server">
               </telerik:RadComboBox>
           </td>
           </tr>
           <tr>
           </tr>
           </table>
           </FormTemplate>
           </EditFormSettings>

CS:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {

        if( (e.Item is GridEditableItem )&&(e.Item.IsInEditMode))
        {
            GridEditableItem formItem = (GridEditableItem)e.Item;
            RadComboBox rdcbx = (RadComboBox)formItem.FindControl("RadComboBox1");

           rdcbx.DataSourceID = "SqlDataSource2";
           rdcbx.DataTextField = "FirstName";
        }
    }

Thanks
Princy.
