ListBox.Sorted Property

Gets or sets a value indicating whether the items in the ListBox are sorted alphabetically.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

member Sorted : bool with get, set

Property Value

Type: System.Boolean
true if items in the control are sorted; otherwise, false. The default is false.

Use the Sorted property to automatically sort strings alphabetically in a ListBox. As items are added to a sorted ListBox, the items are moved to the appropriate location in the sorted list. When adding items to a ListBox, it is more efficient to sort the items first and then add new items.

A ListBox with its Sorted set to true should not be bound to data using the DataSource property. To display sorted data in a bound ListBox, you should bind to a data source that supports sorting and have the data source provide the sorting.

The following code example demonstrates how to use the GetSelected method to determine which items in a ListBox are selected in order to select the items that are not selected and deselect the items that are selected. The example also demonstrates using the SelectionMode property to enable a ListBox to have more than one selected item and uses the Sorted property to demonstrate how to sort items in a ListBox automatically. This example requires that a ListBox, named listBox1, has been added to a form and that the InitializeMyListBox method defined in the example is called from the Load event of the form.
