In my application, i would like to use the popup form concept. When the user clicks a button on page1.aspx, a popup window should appear, with several text box to enter values. On clicking the button on the form, the popup form disappears, the user entered values should get saved into a table and the gridview on page1.aspx will be refreshed then.
Or it is impossible at all. We have to set the size of the form?
