How can I programatically open a new page in a new tab from my codebind file in ASP.NET?

Question

How can I programatically open a page in a new tab from my code behind file in ASP.NET after clicking on a button in my first page? Hopefully, from the new page I could also get to the Session[] array.

Solution 1

"Code behind" runs on the server, no browser instances there to open/use.
Javascript runs in the browser, on the client's computer, it can open a new tab.
If you want, you will have to write a piece in C# that will generate a JavaScript snippet with the window.open Command.

Solution 2

Kelsey's code is correct, but is now depricated, the suggested way to do it now is to use the ScriptManager's methods like this.

ClientScript.RegisterStartupScript(GetType(), "SomeNameForThisScript",
           "window.open('YourPage.aspx');", true);

Solution 3

Just register a window.open command in the start client script.

In your C# client side code (event):

RegisterStartupScript("SomeNameForThisScript", "window.open('YourPage.aspx');");

When you page is served up, the startup script will fire and open a new window. You can customize how the window.open works via attributes.

Does that could involved a reload of the current page?
