public:
void Insert(int index, System::Windows::Media::Visual ^ visual);public void Insert (int index, System.Windows.Media.Visual visual);member this.Insert : int * System.Windows.Media.Visual -> unitPublic Sub Insert (index As Integer, visual As Visual)Parameters
- index
- Int32
The zero-based index at which the value should be inserted.
- visual
- Visual
The Visual to insert into the VisualCollection.
Exceptions
index is less than zero or greater than Count.
Remarks
If Count already equals Capacity, the capacity of the VisualCollection is increased before the new Visual is inserted. If index is equal to Count, visual is added to the end of VisualCollection. Any existing visual objects that are equal to or greater than index are shifted to accommodate the new Visual, and their index values are updated.
The Insert method also sets up the parent-child relationship between the parent visual, which is the owner of the VisualCollection, and the child visual.
If you need greater low-level control over the underlying storage implementation of visual child objects, consider using the AddVisualChild and RemoveVisualChild methods. When you use these methods, you define your own storage implementation, and do not use VisualCollection.
