Remarks

Note

To add the NavBar extension to the View, refer to the NavBar Overview topic.

The object of the MVCxNavBar type represents the configured instance of DevExpress ASP.NET MVC NavBar extension. The MVCxNavBar object is intended to be used mainly as a sender parameter when processing events on the server side.

The code sample below illustrates how to use the MVCxNavBar object within the delegate method that processes the SettingsBase.PreRender server event.

View code:

@Html.DevExpress().NavBar(settings =>
{
    settings.Name = "NavBar";
    settings.PreRender = (sender, e) =>
        {
            MVCxNavBar navbar = (MVCxNavBar)sender;
            // Add a new unbound item. All the other items are taken from the bound "~/App_Data/WorldCup2010.sitemap" file
            navbar.Items.Add("Unbound Item");
        };
}).BindToSiteMap("~/App_Data/WorldCup2010.sitemap").GetHtml()

Note

To properly follow the ASP.NET MVC pattern, it is recommended to respond to end-user actions on the client-side (see Client-Side API) or use Ajax callbacks to the server and handle these callbacks using custom action methods (see Using Callbacks).
