ListBoxItemCollection.Count Property

Gets the number of items in the collection.

Namespace: DevExpress.XtraEditors.Controls

Assembly: DevExpress.XtraEditors.v23.2.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

public int Count { get; }

VB.NET

Public ReadOnly Property Count As Integer

Property Value

Type	Description
Int32	An integer value that specifies the number of items in the collection.

Remarks

When a list box control is bound to a data source via the BaseListBoxControl.DataSource property, its Items collection doesn’t provide access to the data source’s items. So, the Items.Count property doesn’t allow you to get the number of items in the data source. To get the number of items, use the BaseListBoxControl.ItemCount property instead. When the list box control is not bound to a data source, the Items.Count and BaseListBoxControl.ItemCount properties are in sync.
