TemplatedBarManagerController Class

Represents a controller that loads bar customization actions from a DataTemplate object, and executes those applying to a BarManager.

Namespace: DevExpress.Xpf.Bars

Assembly: DevExpress.Xpf.Core.v18.2.dll

Declaration

C#

public class TemplatedBarManagerController :
    BarManagerController

VB.NET

Public Class TemplatedBarManagerController
    Inherits BarManagerController

Remarks

Bar customization actions are objects that are capable of creating the structure of bars or modifying the existing structure of bars. Actions are typically added to a BarManagerActionContainer object, which is storage for actions. When actions are executed, they are executed in the order in which they have been added to the BarManagerActionContainer.

The TemplatedBarManagerController allows you to load and apply bar customization actions that are defined by a BarManagerActionContainer within a DataTemplate object. A DataTemplate object can be defined in resources. This allows the actions to be shared among different windows of a single application or among multiple applications (if the actions are defined in resources of a DLL library).

See Bar Actions to learn more.

Example

This example demonstrates how to modify the current BarManager’s layout in case you do not have direct access to this BarManager. The main idea is to use ControllerBehavior that provides the capability to compose bars or ribbons from templates using built-in Bar Actions.

For versions prior to 15.1:

Use BarManager.Controllers to set a predefined DataTemplate.
