How to set a field in a Detailsview in edit mode

Question

Hey, I have been checking some other questions related to this topic, and have done what they recommend, but none of them worked.

I am having problems setting a field  (a template field - bounded) in a detailsview, when edditing the row.  I have tried several events: ModeChanged, ModeChanging, ItemUpdating, ItemCreated (in edit mode) but none of them works.

What I need to do is simply to set a today's date into a field whenever the row is changed (an audit field), and I also want to see it on the screen

If I try to do this in the itemcreated event (edit mode) ... the control cannot be found.
If I do it in the itemupdating, the control is found, but the value is not set, and even if I update the row, the date field is not set.
I also use the same code when inserting a row, and here it works, I don´t quite understand why it works in the itemcreated event (insert mode), but not when edditing.



The code is this:

TextBox

 

txt;

 

if (DVEmpresa.CurrentMode == DetailsViewMode.Edit)

{

txt =

this.DVEmpresa.FindControl("txtFechModi") as TextBox;

txt.Text =

DateTime.Now.ToString();

}

and the fields is:

<

 

asp:TemplateField HeaderText="Fecha &#218;ltima Modificaci&#243;n" SortExpression="fecultmod">

 

<EditItemTemplate>

 

<asp:TextBox ID="txtFechModi" runat="server" Text='<%# Bind("fecultmod") %>' Font-Names="Calibri" Font-Size="12pt" Height="22px" Width="248px"></asp:TextBox>

 

</EditItemTemplate>

 

<InsertItemTemplate>

 

<asp:TextBox ID="txtFechModi" runat="server" Text='<%# Bind("fecultmod") %>' Font-Names="Calibri" Font-Size="12pt" Width="248px"></asp:TextBox>

 

</InsertItemTemplate>

 

<ItemTemplate>

 

<asp:Label ID="txtFechModi" runat="server" Text='<%# Bind("fecultmod") %>' Font-Names="Calibri" Font-Size="12pt" Height="22px" Width="248px"></asp:Label>

 

</ItemTemplate>

 

</asp:TemplateField>

 

 

I really appreciate some help to solve this.

TIA
