Public Property MergeType As RibbonMergeType

Property Value

Type	Description
RibbonMergeType	A RibbonMergeType value indicating how ribbon pages merge.

Available values:

Name	Description
Add	Adds a child ribbon element to a parent ribbon even if an element with the same caption already exists in the parent ribbon.
Replace	Replaces a parent ribbon element with the current child ribbon element if they have the same caption. If a parent element with the same caption is not found, the current child ribbon element is added to the parent ribbon.
MergeItems	The default merging mechanism. Sub-items of the current child ribbon element are merged into the parent ribbon element that has the same caption. If no parent element with the same caption exists, the current child ribbon element is appended according to its MergeOrder.
Remove	Prevents the current child ribbon element from being merged with a parent ribbon object. If the MergeType for a parent element is set to Remove, this element is hidden after the merge is complete.

Remarks

Use the MergeType property to adjust the way ribbon pages of two ribbon controls merge:

Add

You can set the UseCaptionToIdentifyPagesOnMerging static property to false to avoid possible merging issues.
