Open url in new tab using response.redirect - Asp.Net

Here I am going to explain how to open new tab/window on Button click using asp.net.
A week ago, i have to implement that code. I have option to use javascipt windows.open to open new tab.
But I have to insert or update some database entry. Yeah i know that there is another way to use clientscipt in code behind to achieve this.
But in its simplest form, following code open new tab/window.

<asp:Button ID=”btnNewEntry” runat=”Server” CssClass=”button”  Text=”New Entry” OnClick=”btnNewEntry_Click”  OnClientClick=”aspnetForm.target =’_blank’;”/>

// aspnetForm.target =’_blank’ will add handler to open new tab

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

aspnetForm is the form name, it can be different in some pages, so be sure to check the viewsource of the page you are working on.
Cheers
