I'm writing an ASP.Net registration control that has to do two things:
1) Add the registrant to the database
2) Forward the user to a page on another site to enter credit card information

I'm handling the database update in a button handler, and I would like to open a new window with the page on the other site while in the button handler code. I don't want to use response.redirect because I would like my site to remain on the screen, so I would like to do something similar to the javascript window.open.

Any suggestions?

Thanks

Try this:

Response.Write("<script language=javascript>window.open('site add','new','window parameters');</script>")
