Public ReadOnly Property LayoutManager As LayoutManager

Property Value

Type	Description
DevExpress.ExpressApp.Layout.LayoutManager	A DevExpress.ExpressApp.Layout.LayoutManager descendant that is the current Composite View’s layout manager.

Remarks

To display View Items according to layout settings defined in a DetailView or DashboardView node of the Application Model, XAF applications use platform-specific Layout Managers. Each Layout Manager uses its own component to display controls in a Composite View:

ASP.NET Core Blazor

BlazorLayoutManager: DxFormLayout

Windows Forms

WinLayoutManager: LayoutControl

Technically, an XAF Layout Manager is a wrapper around platform-specific UI controls, and provides a common API for layout customization. Useful APIs of the LayoutManager descendants include:

• ItemCreated and LayoutCreated events – to track layout item creation
• The Container property – to access the underlying layout control instance
• The CustomizationFormEnabled property – an IModelView.CustomizationFormEnabled alternative to disable runtime layout customizations

For more information about layout managers and their customization in XAF, refer to the following topic: Access Form Layout Control in XAF DetailView and DashboardView.
