Using javascript, I have created a "popup" that contains a textbox. I activate it via a button. Once I enter data into the text box, the relative code behind executes, but the "popup" is cleared. It''s as if the "Ok" button is pressed.
How do maintain the visibility of the "popup" until the "Ok" or "Cancel" button is pressed.
