Force all Areas to use same Layout

Question

I have the following project structure:

• /Views/Shared/_Layout;

• /Areas/Area1/Views/ControllerName/Index;

...

• /Areas/AreaN/Views/ControllerName/Index.

Is there any way to force all areas to use the _Layout as a base layout?

Is there any way to do it without adding the _ViewStart file (for example, via the routing configuration)?

Answer 1

You just have to add a file named:

_ViewStart.cshtml

Under each area views folder:

/Areas/Area1/Views/_ViewStart.cshtml

And edit the file to point to the root layout like this:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

In order for this to work, you do not have to specify a value in the view's layout property, if you do, you would be overriding the global layout

Note: As Tony mentioned, you could edit each view's layout property to point to the root layout, however this is not the recommended way to do it since you would be coupling your views with your layout and change it would be painful

Edit 1

If you would like to use code to set the default view's layout, perhaps you should consider writing a custom view engine.

Try to google about custom RazorViewEngine and RazorView

I have not done something like this but I hope I'm pointing you in the right direction
