Question

How can I make it so if you press a number while selecting a DateTimePicker, it won’t modify the value?

Currently, I have an onKeyDown to catch all numbers, and set e.Handled = true, but that still doesn’t seem to override it.

Thanks!

Try overriding the OnKeyPress event instead:

protected override void OnKeyPress(KeyPressEventArgs e) {
  e.Handled = true;
  base.OnKeyPress(e);
}

or if just using the current DateTimePicker without creating your own control:

private void dateTimePicker1_KeyPress(object sender, KeyPressEventArgs e) {
  e.Handled = true;
}

The arrow keys should still work.
