Rad Grid inside Radgrid's column

[Joel]

This is my scenario I have a grid that within one column I added a second grid So far i have populated both of them and the editing in place is working awesome for both grids when performing Insert and Delete actions.

This is my Code (aspx file)

<telerik:RadGrid runat="server" ID="gv_EmployeesObjectives" Width="100%" Font-Names="Arial" Font-Size="12px" Skin="Office2007"
                        AutoGenerateColumns="false"
                        OnItemCreated="gv_EmployeesObjectives_ItemCreated" OnItemDataBound="gv_EmployeesObjectives_ItemDataBound"
                    >
                        <MasterTableView Name="gv_Objectives" DataKeyNames="ID">
                            <Columns>
                                <telerik:GridEditCommandColumn ButtonType="LinkButton" UpdateText="Update" CancelText="Cancel" EditText="Edit" HeaderStyle-Width="90px" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"></telerik:GridEditCommandColumn>

                                        </telerik:RadGrid>
                                    </ItemTemplate>
                                </telerik:GridTemplateColumn>
                            </Columns>
                        </MasterTableView>
                    </telerik:RadGrid>

Everything works perfect, the problem I'm facing is when editing the inner grid....Which is the best method to be able to access the controls within the editTemplate and populate the drop down list i have there.
So far I've tried inner grid's methods OnItemDataBound, OnItemCreated; and it seems the EditTemplate controls aren't there I can only get the ones inside the item template.

any ideas??

Thks in advance...

Hello Joel,

Try the following code.
C#:

protected void grid2_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridEditableItem && e.Item.IsInEditMode)
 {
    GridEditableItem item = (GridEditableItem)e.Item;
    RadComboBox combo = (RadComboBox)item.FindControl("rcb_Products");
 }
}
