How to Redirect to a New Window Using Response.Redirect in ASP.NET?

Opening Links in New Windows with Response.Redirect in ASP.NET

Achieving a Response.Redirect that opens in a new browser tab can be tricky. This guide uses the OnClientClick event in ASP.NET for a clean solution.

To redirect to a new window, add this code to the OnClientClick attribute of your button or link:

OnClientClick="window.open(this.href); return false;"

This will open the link in a new window. However, to avoid unintended consequences on other links, especially if you're using a master page or have multiple links on the page, consider a more targeted approach. Instead of modifying the aspnetForm target, use JavaScript to directly open the link in a new window. The example below shows how to do this.

For example, a modified button would look like this:

<asp:LinkButton ID="myButton" runat="server" Text="Click Me!" OnClientClick="window.open('your-target-url.aspx'); return false;" OnClick="myButton_Click"></asp:LinkButton>

Remember to replace 'your-target-url.aspx' with the actual URL you want to redirect to. The return false; prevents the default postback behavior of the button.

This method ensures only the specified link opens in a new window, maintaining the integrity of other links within your application. This approach offers a more robust and reliable solution compared to modifying the aspnetForm target.
