Gridview error handling

I have a gridview control that is updateable. One of the data elements is
date, which is very easy to misstype. An invalid date will throw an error. Is
there a way to handle that error in a neat and clean manner?

Hi,
Try placing necessary validator controls in the edit template

Thanks for the tip.
I can get the validator to validate a date, but if I add time to the date,
the validator will missfire.
In a regular form I can validate a date+time, but not in a gridview template.

The alternative is to place validation code in the
GridView.RowUpdating event. There you can use DateTime parsing and any
other checks you wish to make. If the validation fails then the event
argument e (GridViewUpdateEventArgs.Cancel) can be used to abort the
update and return the grid to the edit view (using label controls for
error messages).

Try this, it works! :)

Private Sub GridView1_RowUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdatedEventArgs) Handles gvSchedule.RowUpdated
        If e.Exception IsNot Nothing Then
            ErrorMessageLabel.Text = e.Exception.Message
            e.ExceptionHandled = True
            e.KeepInEditMode = True
        End If
    End Sub
