For KeyDown, you can allow it to process the event normally by setting
Handled and SuppressKeyPres s properties of KeyEventArgs to false (or
not touching those properties in the first place, since their default
value is false). You cannot rewrite keycodes in KeyDown event handler,
though.

In KeyPress event handler, you can modify input characters simply by
changing the value of KeyPressEventAr gs.KeyChar property. Again,
unless you set Handled to true, the default processing will take place
after your event handler returns, and the modified character value
will be used (e.g. inserted into the text in case of TextBox).

Re: Event Handlers

Pavel,

Using the keypressed event worked like a charm! I can now manage a regular
TextBox as I might have used a masked text box and as a bonus not have to put
up with the ugly placeholders. I just "swallow" the unwanted characters.

Thank you so very much for the help.
