Remarks

The Web Dashboard allows you to separate the client and server. This means you can:

• Integrate a dashboard in any place that supports HTTP requests (e.g., websites, web applications).
• Publish Web Dashboard as a part of applications based on Angular, Knockout, Vue and similar frameworks.
• Use the Dashboard side-by-side with DevExtreme client-side widgets to create highly responsive web apps.

The table below illustrates correlations between server and client. The row headers display platforms you can use as a server, the column headers show available client counterparts.

Server \ Client	ASP.NET Web Forms	ASP.NET MVC	ASP.NET Core	HTML JS
ASP.NET Web Forms (UseDashboardConfigurator = false)	-	-	-	-
ASP.NET Web Forms (UseDashboardConfigurator = true)		-	-	-
ASP.NET MVC
ASP.NET Core

Use the DashboardBuilder.BackendOptions method to configure a server from the client application:

Platform	Member
ASP.NET Web Forms	ASPxDashboard.BackendOptions
ASP.NET MVC	DashboardExtensionSettings.BackendOptions
ASP.NET Core
HTML JS	DashboardControlOptions.endpoint / FetchRemoteServiceOptions.headers

The following code snippets show how to configure the client: to set the server’s url and pass a custom Authorization header. Note that the server’s url should consist of a base URL (where the Web Dashboard’s server side is hosted) and a route prefix (a value that is set in the MVC / .NET Core MapDashboardRoute properties).

For MVC or ASP.NET Core back-end, the url is a controller’s address:

ASPxDashboard

DashboardControl.BackendOptions.Uri = "{baseURL}/api/dashboard";
DashboardControl.BackendOptions.RequestHttpHeaders.Add("Authorization", "AuthToken123");

MVCxDashboard

DashboardControl.BackendOptions.Uri = "{baseURL}/api/dashboard";
DashboardControl.BackendOptions.RequestHttpHeaders.Add("Authorization", "AuthToken123");

ASP.NET Core Dashboard

@(Html.DevExpress().Dashboard("dashboardControl1")
    .BackendOptions(options => options.Uri("{baseURL}/api/dashboard").RequestHttpHeaders(headers => { headers.Add("Authorization", "AuthToken123"); }))
)

HTML JavaScript control

<script>
  window.onload = function () {
    var dashboardControl = new DevExpress.Dashboard.DashboardControl(document.getElementById("web-dashboard"), {
        endpoint: "{baseURL}/api/dashboard",
        fetchRemoteService: {
            headers: {
                'Authorization': 'AuthToken123'
            }
        }
    });
  }
</script>
