Declaration
Property Value
| Type | Description |
|---|---|
| BarItemMergeType | A BarItemMergeType enumerator value that is the merge type for all items owned by this BackstageViewControl. |
Available values:
| Name | Description |
|---|---|
| Default | Acts identically to the Add value. |
| Add | Specifies that the child BarManager’s BarItemLink should be added to a bar/link container of a parent BarManager. When merging bars and link containers, the position to insert the BarItemLink is determined by the BarItemLinkBase.MergeOrder properties of this link and of the links within the target bar/link container. |
| Replace | Indicates that the child BarManager’s BarItemLink should replace the parent BarManager’s link that has the same BarItem.Content, but only if the parent link’s BarItemLinkBase.MergeType property is also set to Replace. If such a link is not found in the parent BarManager’s bar/link container, the child BarManager’s link will be added to the bar/link container (similar to the Add setting). |
| MergeItems | This setting is applied to link containers (e.g. sub-menu). It specifies that subitems of the child BarManager’s link container should be merged with subitems of a parent BarManager’s link container. Merging occurs for the parent BarManager’s link container, when the type and BarItem.Content match the source item, and only if its BarItemLinkBase.MergeType property is set to MergeItems. Otherwise, the child BarManager’s link container will be added to the parent BarManager’s bar (similar to the Add setting). |
| Remove | For a child BarManager’s BarItemLink, indicates that the link must not be added to the parent BarManager’s bar/link container during merging. For a parent BarManager’s BarItemLink, indicates that the link must be removed from the bar/link container during merging. |
Remarks
To override the ItemMergeType setting for individual backstage items, utilize their BackstageItemBase.MergeType properties. See MDI Bar Merging article to learn more.
