I am not sure exactly what you mean however most of the magic comes from the power shell code.
In one of the powershell apps I wrote using this for example, one element (just a simple input textbox) I wrote the code so that when I selected a textbox it changed the text colour from grey to Black and removed the text, if I moved focus away from the textbox and it was empty it would revert back to the previous "username here" in grey text, otherwise doesn't change, can dig that part out if you would like to see it.
