Response.Redirect to New Window

Response.Redirect to New Window

If you have multiple buttons and you want one or some buttons to redirect to a page in another window, use following code.

1. Button redirecting to a page in new window

<asp:Button ID="btnNewWindow" runat="Server" Text="New Window"

OnClick="btnNewWindow_Click" OnClientClick="aspnetForm.target ='_blank';"/>

protected void btnNewWindow_Click(object sender, EventArgs e)
{
    Response.Redirect("NewPage.aspx");
}

2. Button redirecting to a page in same window

<asp:Button ID="btnSameWindow" runat="Server" Text="Same Window"

OnClick="btnSameWindow_Click" OnClientClick="aspnetForm.target ='_self';"/>

protected void btnSameWindow_Click(object sender, EventArgs e)
{
    Response.Redirect("SomePage.aspx");
}

It is imperative that you add OnClientClick="aspnetForm.target ='_self';" 

on the button in which you want to redirect to a page in Same Window, otherwise

all Response.Redirect in this page will start to open in New Window.

No Java scripts :)
