React Toolbar - items

The items array can contain:

• Strings
• Objects with fields described in this section
• Objects with any other fields. In this case, specify the itemTemplate.

If you need to update the widget items, reassign the entire items array as shown in the following example:

toolbarInstance.option('items', newItems);

As an alternative to items, you can use the dataSource option. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.

Use the ToolbarItemLocateInMenuMode enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Always, Never, and Auto.

Whatever template you use for widget items (default or a custom) will be located according to the value specified for the location field in the item data source object.

Use the ToolbarItemLocation enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Before, After, and Center.

The following types of the specified value are available.

• Assign a string containing the name of the required template.
• Assign a jQuery object of the template's container.
• Assign a DOM Node of the template's container.
• Assign a function that returns the jQuery object or a DOM Node of the template's container.

options should contain the options of the DevExtreme widget specified in the widget option. Because of this dependency, options cannot be typed and are not implemented as nested configuration components in Angular, Vue, and React. In these frameworks, specify options with an object. We recommend that you declare the object outside the configuration component in Vue and React to prevent possible issues caused by unnecessary re-rendering.

When using ASP.NET MVC 5 Controls or DevExtreme-Based ASP.NET Core Controls, configure this option with a lambda expression as follows:

@(Html.DevExtreme().Toolbar()
    .Items(items => {
        items.Add().Widget(w => w
            // Instead of Button here you can use any other widget
            .Button()
            .Text("Back")
        );
    })
)

@(Html.DevExtreme().Toolbar() _
    .Items(Sub(items)
        items.Add().Widget(Function(w)
            ' Instead of Button here you can use any other widget
            Return w.Button().Text("Back")
        End Function)
    End Sub)
)
