Related API Members

BarManagerMergeEventArgs is the data class for the following events:

• BarManager.Merge
• BarManager.UnMerge

Remarks

For MDI applications, XtraBars provides bar merging functionality which allows you to combine the bars of the parent and child MDI forms. The merge and corresponding unmerge mechanisms are invoked based on the BarManager.MdiMenuMergeStyle property value.

The BarManager.Merge event is fired by the merge mechanism to let you manually merge specific bars belonging to the parent and child MDI forms, as required. To undo the merge results, handle the BarManager.UnMerge event, which is fired when required by the unmerge mechanism. See the BarManager.Merge topic for more information.
