ListViewGroupCollection.Contains(ListViewGroup) Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

ListViewGroupCollection.cs

Determines whether the specified group is located in the collection.

C#

public bool Contains(System.Windows.Forms.ListViewGroup value);

Parameters

value

ListViewGroup

The ListViewGroup to locate in the collection.

Returns

Boolean

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.
