Open a page in a new tab on button click from code behind

To open a new page in a new tab from a hyperlink is an easy thing but from a code behind is not a easy one to do. In this example I will show you how to redirect to a new page from code behind in C#.

First create a new project and add two new pages. page1.aspx and page2.aspx

Now in page1.aspx add two new buttons. In the code behind of two buttons add bellow codes.

Method 1 :
This is to open a page in pop up.

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Open in Popup" OnClick="Button1_Click" />
    </div>
    </form>
</body>

Now in the code behind

/// <summary>
/// in pop up/// </summary>
/// <param name="sender"></param>       
/// <param name="e"></param>
protected void Button1_Click(object sender, EventArgs e)
{
     Page.ClientScript.RegisterStartupScript(
          this.GetType(), "OpenWindow", "window.open('2.aspx','_newtab');", true);
}

Method 2 :
This is to redirect a page in a another tab.

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button2" runat="server" Text="Open in Other Tab"
            onclick="Button2_Click" OnClientClick="document.forms[0].target ='_blank';" />
    </div>
    </form>
</body>

And the code is simpler even.

/// <summary>
/// in other tab
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Button2_Click(object sender, EventArgs e)
{
     Response.Redirect("2.aspx");
}
