Edit button in datagrid doesn't work!?

[Ante Perkovic]

Hi,

I have this piece of code:
<asp:datagrid id="dgRezervirano" runat="server" CssClass="rezervacije"
AutoGenerateColumns="false" DataKeyField="id" Width="650px">
....
<asp:EditCommandColumn ButtonType="PushButton" UpdateText="OK"
CancelText="Cancel" EditText="Edit"></asp:EditCommandColumn>

and in codeBehind, I have:
Private Sub dgRezervirano_EditCommand(ByVal source As Object,
ByVal e As DataGridCommandEventArgs) Handles dgRezervirano.EditCommand
dgRezervirano.EditItemIndex = e.Item.ItemIndex
...
End Sub

But, when I click on a "Edit" button, nothing happens!!! I tried with
breakpoints, but that code is never run!!!

Anybody have an idea why? And it did work 10 minutes ago!

I'm in front of PC for the last 10 hours, so I may be missing
something.

Can anybody help me?

Ante
