Open mvc view in new window from controller

You can use Tommy's method in forms as well:

@using (Html.BeginForm("Action", "Controller", FormMethod.Get, new { target = "_blank" }))
{
//code
}

You're asking the wrong question. The codebehind (controller) has nothing to do with what the frontend does. In fact, that's the strength of MVC -- you separate the code/concept from the view.

If you want an action to open in a new window, then links to that action need to tell the browser to open a new window when clicked.

A pseudo example: <a href="NewWindow" target="_new">Click Me</a>

And that's all there is to it. Set the target of links to that action.

This cannot be done from within the controller itself, but rather from your View. As I see it, you have two options:

1. Decorate your link with the "_blank" attribute (examples using HTML helper and straight HMTL syntax)

   • @Html.ActionLink("linkText", "Action", new {controller="Controller"}, new {target="_blank"})
   • <a href="@Url.Action("Action", "Controller")" target="_blank">Link Text</a>

2. Use Javascript to open a new window

   window.open("Link URL")
