ButtonColumn and EditCommandColumn don't work together as expected in DataGrid

Hi,

I have a DataGrid with standard EditCommandColumn with PageIndex enabled.
Everything works fine.
When I add ButtonColumn

   <asp:ButtonColumn
      Text="Delete"
      HeaderText=""
      CommandName="Delete"/>

and modify DataGrid with

     OnItemCommand="datagrid_Delete"

strange things happen. It seems to work until I click one of "Edit" buttons.
It changes properly to edit mode but then no matter what button I click next
("Cancel", "Update", some other "Edit" or one of page changing buttons) it
always runs OnItemCommand, and what's very strange, CommandName property has
always "Delete" value instead of "Cancel" , "Update" or whatever name of
button I clicked:

        protected void datagrid_Delete(object o, DataGridCommandEventArgs e)
{
               Response.Write("I clicked " + e.CommandName);
               ...
        }

        gives:

        I clicked Delete

Strangly it works after another click...
Why the h... is that?

Thanks,
Piotr

The EditCommandColumn server control fires up the ItemCommand event just like
the Delete button does. What you need to do is to find out during the
ItemCommand handling which command was clicked. You should set the
OnItemCommand="DataGrid1_Command" and within that method:

protected void DataGrid1_Command(object sender, DataGridCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "Delete":
                                       //process the delete command
                                       break;
    }
}

That's exactly what I did. The point is after I click Cancel or Update
e.CommandName should be "Cancel" or "Update" but it turns out to be "Delete"
Why?
