Sometimes you need to modally display an ASP.NET page, that is, you can't allow you to click on other pages before you close this page, just like a dialog in a lot of Windows programs. This effect can be implemented using DHTML's WindowModalDialog method, as follows:
(1) Place an HTML button in the call page
Top: 289px; Height: 38px "Type =" Button "value =" show dialog "οnclick =" OpenDialog () ">
(2) Join Script at this page
