TdxBarManager.OnBeforeMerge Event

Fires when the bar manager is about to raise the OnMenuMerge or OnMerge event.

Declaration

property OnBeforeMerge: TdxBarMergeEvent read; write;

Remarks

OnBeforeMerge and OnAfterMerge are notification events that enable you to respond to merge operations. Handle these events only to update form elements without merging – any merge operation must be performed in the OnMenuMerge and OnMerge event handlers.

The events use identical parameters. Refer to the OnMenuMerge or OnMerge event description for detailed information on them.
