警告
Removed. TreeView is now deprecated. You can likely now use TreeView\<int\> instead and not think more about it. But if you were using that identifier to store EntityId data, you should instead opt to upgrade your TreeViews to use TreeView\<EntityId\> to get the proper typing.
protected virtual bool CanBeParent(TreeViewItem item)
Parameters
Can this item be a parent?
Returns
Type | Description |
|---|---|
| bool |
Remarks
This is called internally by the TreeView to determine dragging behavior. For list views this function should just return false to prevent any reparenting. Default behavior: returns true.
