Namespace: DevExpress.Xpf.Bars
Assembly: DevExpress.Xpf.Core.v19.1.dll
Declaration
Property Value
| Type | Description |
|---|---|
| MDIMergeStyle | A MDIMergeStyle value specifying if the BarManager’s bars can be merged. |
Available values:
| Name | Description |
|---|---|
| Default | Identical to the MDIMergeStyle.Always value. |
| WhenChildActivated | The merging mechanism is invoked when a maximized MDI child panel is activated. In the case of a tabbed UI, the merging mechanism is invoked when a selected tab is activated. The unmerge mechanism is invoked when a maximized MDI child panel is restored from the maximized state to the normal state, or when it is deactivated. In the case of a tabbed UI, the unmerge mechanism is invoked when a selected tab is deselected or deactivated. |
| Always | The merging mechanism is invoked when an MDI child panel is maximized in a DocumentGroup. In the case of a tabbed UI, it is invoked when a tab is selected in a DocumentGroup. If there are multiple DocumentGroups, the merging mechanism is invoked for all DocumentGroups simultaneously, thus all of them are merged to the parent at the same time. The unmerge mechanism is invoked when an MDI child panel is restored from the maximized state to the normal state, or in case of the Tabbed UI, when another tab is selected. |
| Never | Prevents all child tabbed and MDI panels from being merged. |
| WhenLoadedOrChildActivated | Similar to the WhenChildActivated mode. Additionally, merges those MDI panels and tabs that are initially maximized (docked), but not yet selected (e.g., on application start). |
Remarks
The merging mechanism is invoked according to the DockLayoutManager.MDIMergeStyle and DocumentPanel.MDIMergeStyle properties.
You can prevent bars that belong to the current BarManager from being merged by setting the BarManager.MDIMergeStyle property to MDIMergeStyle.Never. If the BarManager.MDIMergeStyle property is set to other values, the merging is enabled for the current BarManager.
