[Solved] Modify a control in a TemplateColumn when in Edit Mode.

[hk proj]

Hi, I'm having troubles using RadGrid.
I am using the following declaration to create a TemplateColumn:

	<rad:GridTemplateColumn UniqueName="masterpage" HeaderText="<%$ Resources:Grids,Portals_MasterPage %>" >
	<ItemTemplate><asp:Label ID="labelMasterPage" runat="server" Text='<%# GetFileName(Eval("masterpagefile").ToString()) %>' /></ItemTemplate>
	<EditItemTemplate>
	<asp:DropDownList ID="dropDownFileNames" runat="server" DataSource='<%# GetMasterPages(Eval("homedirectory").ToString()) %>' />
	</EditItemTemplate>
	</rad:GridTemplateColumn>

I want to modify the SelectedValue property of the DropDownList in the EditItemTemplate when the row goes in Edit Mode.
But the problem is that whenever I search the dropdownlist in a GridEditableItem (inside EditCommand event, for example), I receive the 'NullReferenceException'.
How can I solve this problem?
Thanks in advance.
PS: I'm using RadControl 3.5 in ASP.NET 3.5.

Ok, solved.
I used the following code:

        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            var item = e.Item as GridEditableItem;
            (item["masterpage"].FindControl("dropDownFileNames") as DropDownList).SelectedValue = item.GetDataKeyValue("masterpagefile").ToString();
        }

Hope it helps.
Bye.
