Angular SPA Framework - Markup Components - Command - Configuration

You can configure this option in an ASP.NET MVC Control as follows:

@(Html.DevExtreme().WidgetName()
    .ElementAttr("class", "class-name")
    // ===== or =====
    .ElementAttr(new {
        @id = "elementId",
        @class = "class-name"
    })
    // ===== or =====
    .ElementAttr(new Dictionary<string, object>() {
        { "id", "elementId" },
        { "class", "class-name" }
    })

)

@(Html.DevExtreme().WidgetName() _
    .ElementAttr("class", "class-name")
    ' ===== or =====
    .ElementAttr(New With {
        .id = "elementId",
        .class = "class-name"
    })
    ' ===== or =====
    .ElementAttr(New Dictionary(Of String, Object) From {
        { "id", "elementId" },
        { "class", "class-name" }
    })
)

This option accepts a value of one of the following types:

• Number
  The height in pixels.

• String
  A CSS-accepted measurement of height. For example, "55px", "80%", "auto", "inherit".

• Function
  A function returning either of the above. For example:

  JavaScript

  height: function() {
      return window.innerHeight / 1.5;
  }

This option can take on the name of an icon from the built-in icon library.

Setting this option is mandatory, since a command identifier is required when defining an application's command mapping. The identifier should be unique throughout the entire application.

Assign a function to perform a custom action when the command is executed.

You can assign a URL to which the browser will navigate when the widget is clicked. The URL can be presented as a string or an object, both conforming to the navigation routing registered in the application. In addition, you can specify navigation parameters. For this purpose, specify command options with the same names as the fields of the options object passed as the second parameter to the HtmlApplication.navigate(uri, options) method. For details on using commands for navigation, refer to the Navigate to a View topic.

You cannot access widget elements in this handler because it is executed before they are ready.

When this option is set to true, the widget text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

DevExpress.config({
    rtlEnabled: true
});

• Number
  The width in pixels.

• String

  JavaScript
