How to open link in new window using Response.Redirect

One of the neatest ways I've ssen to open a new window with Response.Redirect is indicated here[^]. As it states, you cannot open a new window with the standard redirect method because of the way it works internally (i.e. it sends a special HTTP request to trigger the redirect), so you need to apply a little bit of mojo to get it working.

Use this code in button click event (code behind) it will open the page in new window

string url = "WebForm.aspx";
            Response.Write("<script type='text/javascript'>window.open('" + url + "');</script>");

HTML Code:

<asp:Button ID="btnNewEntry" runat="Server" CssClass="button" Text="New Entry"

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

Button Click cs file:

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

Basically using code behind there is no direct way to open link in new window, but using target attribute of link you can achieve it, set target to '_blank', it will help you to open page in new window
OR
you can use JavaScript for it, window.open method will help you to do it
see below snippet

function openMe()
{
window.open("1.aspx",'_blank');
return false;
}

Use the below code to open link in new window.

Response.Write(" window.open('"+ url + "', 'window');");
