Hello,

I'm working on an older application now which uses Ultragrid v3.1.

In the ultragrid the user can enter a date (with mask __/__/____). If there is allready a date in the cell and the user wants to clear it, he'll get an error when he leaves the cell ("Unable to update the data value: Value in the editor is not valid") . When there is a DBNull value in the database the ultragrid just shows an empty cell.

I want the user to be able to clear the date so that the cell will be empty again.

This Is what I've tried so far.

Private Sub UltraGridKlantengroep_Error(ByVal sender As System.Object, ByVal e As Infragistics.Win.UltraWinGrid.ErrorEventArgs) Handles UltraGridKlantengroep.Error
            Dim thisUltragrid As Infragistics.Win.UltraWinGrid.UltraGrid = CType(sender, Infragistics.Win.UltraWinGrid.UltraGrid)
            If (thisUltragrid.ActiveCell.Text = "__/__/____") Then

                Me.UltraGridKlantengroep.ActiveCell.Value = DBNull.Value
            End If
            e.Cancel = True

        End Sub

If I do this I get an unhandled exception:

Internal error: can't get masked editor value.

Inner exception: Input does not match the mask.

Any ideas how I can fix this?
