I am very new to MVC and I am updating a web form application to mvc. I have a shared layout (masterpage in webforms), I would like to set the meta and title information per view but I see no options for this. thanks for any help.
Typically, in your layout, you'll have something like this:
<!DOCTYPE html>
<html lang="en">
<head>
<title>@ViewBag.Title</title>
<!-- the rest omitted for brevity -->
The important part is @ViewBag.Title
. This bit of razor syntax encodes and writes the value of ViewBag.Title
. ViewBag
is a property on all razor views to a dynamic type that uses the ViewData
dictionary as its backing store. ViewData
is just a dictionary where you can store random stuff that you want to use in your view.
In your controller, layout, or view, you can get or set ViewBag.Title
. Here's an example of how to set it in a view that uses your layout (called _Layout.cshtml
in this example):
@{
ViewBag.Title = "My View's Title";
Layout = "~/Views/Shared/_Layout.cshtml";
}
You can access the model metadata from ViewData.ModelMetadata
. In this example, I enumerate the properties of the model and display the names:
<ul>
@foreach (var property in ViewData.ModelMetadata.Properties)
{
<li>@property.PropertyName</li>
}
</ul>
In your method of controller.
ViewData["Title"] = "this is page one title";
in you view, have this.
@ViewData["Title"])
if title is html, it should be @html.raw(ViewData["TopMessage"])
Razor engine is better for mvc, so I recommend you try razor when you create a new project. hope it help you.
I like to set page titles dynamically using the action and controller names. You can use a library like Humanizer to convert "SomeActionName" into "Some action name":
public static class HtmlHelperExtensions
{
public static MvcHtmlString GetPageTitle(this HtmlHelper helper)
{
var actionName = helper.GetRouteDataValue("action");
var controllerName = helper.GetRouteDataValue("controller");
return new MvcHtmlString(controllerName.Humanize() + " - " + actionName.Humanize());
}
private static string GetRouteDataValue(this HtmlHelper helper, string value)
{
return helper.ViewContext.RouteData.Values[value].ToString();
}
}
and then in your _Layout:
<title>@Html.GetPageTitle()</title>
