>In one of the textboxes a receipt number is entered. Currently it is something like H5769. To make provision for future larger numbers ie T65789 I want to pad the number H5769 to H05769. Do I put the code to do this in the LostFocus property?

You can put this code into LostFocus() but make sure it fires when you jump straight to SAVE button from this textbox.

Input mask should be 'X99999'.
