Pressing TAB brings you to NumericUpDown control normally, then all
you have to do is to handle GofFocus event as follows:
' Code Lines are splitted for a proper paste
' Select entire value
Private Sub NumericUpDown1_GotFocus _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles _
NumericUpDown1.GotFocus
NumericUpDown1.Select(0, _
NumericUpDown1.Value.ToString.Length)
End Sub
Hope this helps,
