ListViewGroupCollection.Contains(ListViewGroup) ListViewGroupCollection.Contains(ListViewGroup) ListViewGroupCollection.Contains(ListViewGroup) ListViewGroupCollection.Contains(ListViewGroup) Method

Definition

Determines whether the specified group is located in the collection.

public:
 bool Contains(System::Windows::Forms::ListViewGroup ^ value);
public bool Contains (System.Windows.Forms.ListViewGroup value);
member this.Contains : System.Windows.Forms.ListViewGroup -> bool
Public Function Contains (value As ListViewGroup) As Boolean

Parameters

value
ListViewGroup ListViewGroup ListViewGroup ListViewGroup

The ListViewGroup to locate in the collection.

Returns

true if the group is in the collection; otherwise, false.

Remarks

You cannot add a ListViewGroup to the collection more than once. However, attempting to add another copy will not throw an exception. Instead, the addition will simply fail. The Add method will return a value of -1 in this case. The AddRange and Insert methods, however, do not have return values. When adding groups using one of these methods, use the Contains method to determine whether a particular ListViewGroup is already in the collection.
