ButtonColumn and EditCommandColumn don't work together as expected

[Piotr]

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

Hi Piotr,





Various button_click (including Sorting, Paging, Edit, Update, and so on) in
a datagrid goes datagrid_ItemCommand event first, then to be switched to
individual event accordingly. Hence, if you have the event, you should
filter (by e.CommandName) to allow only specified command to be handled
there.

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 is taht?
