Based on the video example about using modal Popupextender. But the only changes i did is replace the option controls to textbox controls. The flow will only display the text on what I've inputted on the textbox in the modal window. The problem is how am I going to refresh the value of the textbox to null everytime I clicked the button to popup the modalwindow?
