Question How to open popup window and redirect to another page

[Sriram Surampudi]

I have a situation, when I click on a button, I need to open a URL in browser's pop-up window and then redirect the current page to another page using VB.NET.
But when I click on the button, I am not seeing the pop-up window but page is redirecting based on the condition.
To open the popup window I am using the ScriptManager.RegisterStartupScript( ) and then using response.redirect("xyz.aspx")

Could any one guide me on this.
