RibbonControl.UnMerge Event

Allows you to perform additional customizations after another Ribbon Control has been unmerged from the current RibbonControl.

Namespace:DevExpress.XtraBars.Ribbon
Assembly:DevExpress.XtraBars.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type DevExpress.XtraBars.Ribbon.RibbonMergeEventArgs containing data related to this event.

Expanded Remarks

In MDI applications, Ribbon Controls of child and main MDI forms can be merged according to the MdiMergeStyle property of the main Ribbon Control object. This property also determines when the unmerge mechanism is invoked, restoring the original layout of bar commands within the main and child Ribbon Controls. The UnMerge event fires after the main and child Ribbon Controls have been unmerged.

RibbonStatusBar objects within the main and child MDI forms are not merged automatically. To merge them, handle the Merge event and call the RibbonStatusBar.MergeStatusBar methods. To unmerge them (restore the original layout of status bars), handle the UnMerge event and call the RibbonStatusBar.UnMergeStatusBar method.

See Ribbon Merging to learn more.

Expanded Example

The following example shows how to merge RibbonStatusBar objects in an MDI application, when the Ribbon merging mechanism is invoked. It's assumed that both the parent and child MDI forms contain RibbonStatusBar objects. To merge them, the RibbonStatusBar.MergeStatusBar method is called in a Merge event handler. To unmerge the status bars, the RibbonStatusBar.UnMerge method is called in a UnMerge event handler.
