akki

i am developing a webform in which there is a preview button.On
pressing the button, I have to open a new window and display another
aspx page there.Can anyone tell me how to do it? Response.redirect
opens the new page in the same window.

There is no way to make ASP.NET open a new browser window. You can, however,
include dynamically generated Javascript code to open a new window with the
desired URL. The necessary information can be passed to this window using
whatever technique you want, including querystring, Session, etc. Opening
new windows is performed by the browser, so ASP.NET has no control over it.
However, keep in mind that many browsers have pop-up blockers that may
prevent Javascript from opening this new window (it will usually inform the
user and give them the option of opening it, but it waits for the user's
confirmation, so you should tell them why the browser will be trying to open
a new window). Good Luck!

Hi Akshay,

Here's a page in ASP.NET 2.0 that shows one way to accomplish what you need.
Let us know if it helps?

You can use ajax to display new windows it works from codebehind.
Unfortenately I can't give you a link, because I am new at this forum and can't post links, but you can send me a message and I send you a link with very good explanations how to do it.
