Datagrid / Postback Question

[S. Justin Gengo]

Craig,

1) Populate the data grid on page load only:

If Not IsPostBack Then
'---Populate your grid the first time.
End If

2) Delete the record and then repopulate the grid. (If you do this put the
routine that populates your grid into a subroutine and call that subroutine
in the IsPostBack area and call it again after you delete the data.

Sincerely,

Perfect... I'm still used to classic ASP and having to get adjusted :)

Your advice worked perfectly - thanks...
