Question

I have a text box on a form and want to perform different actions when it receives focus depending on how the focus was received.

If the user clicks on the text box I want the standard method where the cursor is placed at the end of the text string inside the box. If the user tabs to the text box I want all of the text contained within the text box to be selected.

Is there an elegant way to accomplish this?

I suppose one thing you could try would be to set some application-level (or parent-level) tunneling events so you can toggle a flag indicating it was mouse clicked or keyboard pressed (PreviewMouseDown and PreviewKeyDown). Depending on what was previously pressed by checking that flag, you could do the appropriate action when the text box gets focus.
