    Try the following code snippet to fill the DropDownList in Insert mode.

     <telerik:GridTemplateColumn HeaderText="TempCol" UniqueName="TempCol" > 
                       <asp:DropDownList ID="RCBAccDocType" runat="server"

     protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
            if ((e.Item is GridEditFormInsertItem) && (e.Item.OwnerTableView.IsItemInserted)) 
                GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item; 
                DropDownList combo = (DropDownList)insertItem["TempCol"].FindControl("RCBAccDocType"); 
                SqlConnection conn = new SqlConnection(connectionstring); 
                SqlDataAdapter adp = new SqlDataAdapter("select ProductName,ProductID from  Products ", conn); 
                DataTable dt = new DataTable(); 
                combo.DataSource = dt; 
                combo.DataTextField = "ProductName"
                combo.DataValueField = "ProductID"

    Thanx for you help buddy. :)

    I am attaching your code in :

    If (TypeOf e.Item Is GridEditFormInsertItem) AndAlso (e.Item.OwnerTableView.IsItemInserted) Then
                Dim insertItem As GridEditFormInsertItem = DirectCast(e.Item, GridEditFormInsertItem)
                Dim combo As DropDownList = DirectCast(insertItem("Roles").FindControl("RCBAccDocType"), DropDownList)
                combo.DataSource = dsh.PersonnelRole
                combo.DataTextField = "RoleName"
                combo.DataValueField = "PersonnelRoleID"
            End If

    Hi Maulin,

    I am afraid you cannot bind the RadComboBox on the client since grid requires the selected value to be send to the server. Nevertheless, a possible solution is to use load on demand feature of the ComboBox control to populate it. Please check out the following live example which demonstrates that.

    Do you need help with upgrading your ASP.NET AJAX, WPF or WinForms projects? Check the Telerik API Analyzer and share your thoughts.
