Grid cell access in TemplateColumn

[Alin]

Hello, I have a grid-template-column defined like this( to save time and space i'll only put the column) :

<telerik:GridTemplateColumn HeaderText="Id" Reorderable="true" SortExpression="Id" UniqueName="Id" DataField="Id">
                    <ItemTemplate>
                        <asp:Label ID="lblId" runat="server" Text='<%# Eval("Id") %>' />
                    </ItemTemplate>
                    <EditItemTemplate>
                        <telerik:RadTextBox ID="txbId" Width="50px" runat="server" TextMode="SingleLine"
                            Text='<%# Bind("Id") %>' />
                    </EditItemTemplate>
                    <ItemStyle VerticalAlign="Top" />
             </telerik:GridTemplateColumn>

And I want on the PreRender event, to extract the value of this column

protected void RadGrid1_PreRender(object sender, System.EventArgs e)

    {

        //string selectedItem = ((GridDataItem)RadGrid1.SelectedItems[0])["Id"].Text;

        foreach (GridDataItem item in RadGrid1.Items)

        {

            //not working

            string k = item["Id"].Text;// is empty string
// null pointer


            string key = (item["Id"].TemplateControl.FindControl("txbId") as RadTextBox).Text;

}

The grid is already databinded! 

Any idea how to fix it? PLZ!!!

Thx a lot.

foreach (GridDataItem item in grdHeader.EditItems)
                {

                    GridEditableItem edititem = (GridEditableItem)item.EditFormItem;

                    RadTextBox txtHeaderName = (RadTextBox)edititem.FindControl("txbId");

                }
