I'm just calling the onchange event of the textbox after inserting a text into the textbox, so you can do whatever you want in the onchange event of the text like reformatting or changing text, etc Sorry, but I think you have misunderstood my question.

The JavaScript file that I am using enters the value into the TextBox by using the textbox id as a parameter in order to return the date. It is this returned value that I want to reformat when it enters the textbox without needing to make the user click another button. I need it to be all automatic.
