ASP.Net Open New Tab in Browser from CodeBehind

Question

I need to open a browser tab from a link that is given to me by an asp.net code behind. Normally I would have a link and target="_blank", but the link that I need is dynamic, so I must have the behavior of a _blank link from code behind.

Any Ideas?

If you have the data needed to create the link when generating the initial HTML, you can do something like this in the Page_Load event:

protected void Page_Load(object sender, EventArgs e)
{
    Button1.OnClientClick="javascript:window.open('MyPage.aspx?Param=" + Param1.ToString() + "');";         }
}

If you're waiting for the PostBack to get the required data to build the link, you can send javascript down to the browser via the ScriptManager:

protected void Button1_Click(object sender, EventArgs e)
{
    //process whatever you need to to get Param1
    ScriptManager.RegisterStartupScript(Page, typeof(Page), "OpenWindow", "window.open('MyPage.aspx?Param=" + Param1.ToString() + "');",true);
}
