Configuration

An object defining configuration options for the widget.

activeStateEnabled

A Boolean value specifying whether or not the widget changes its state when interacting with a user.

Type: Boolean
Default Value: false

This option is used when the widget is displayed on a platform whose guidelines include the active state change for widgets.

contentTemplate

A template to be used for rendering widget content.

Type: template
Default Value: 'content'
NOTE
A binding context of a content template is the bound view model. So, you can bind template elements to the view model's fields directly. To access another binding context within a title template, use the Knockout/AngularJS binding variables.

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

The widget height.

  • string
    A CSS measurement of the widget height (e.g., "55px", "80%", "auto" and "inherit")

  • function
    A function returning the widget height, e.g.,

    JavaScript
    height: function () {
        return baseHeight - 10 + "%";
    }

Normally, the menu is located at the left side of the screen. Assign 'inverted' to this option to display the menu at the opposite side.

When configuring the widget using ASP.NET MVC Wrappers, specify this option using the SlideOutMenuPosition enum. This enum accepts the following values: Normal and Inverted.
