MultiSelect Property

Visual Studio .NET 2003

Specifies whether a user can make multiple selections in a ListBox control and how the multiple selections can be made. Available at design time; read/write at run time.

ListBox.MultiSelect[ = nChoice]

Property Values

nChoice
The settings for the MultiSelect property are:
Setting Description
0 (Default) Multiple selection isn't allowed.
1 Multiple selection is allowed. To select multiple items in a ListBox control, hold the CTRL key down while clicking the items.

Remarks

Set MultiSelect to true (.T.) to enable a user to select multiple items in a list. You can use the Selected property to determine which items are selected.

Example

The following example creates a ListBox. The MultiSelect property for the list box is set to true (.T.), allowing you to make multiple selections from the list box. The source of the items that appear in the list box items is an array; the array is specified with the RowSourceType and RowSource properties.

The ListCount property is used within a FOR ... ENDFOR loop to display the item or items you choose in the list box. The Selected property is used to determine the items you chose, and the List property is used to return the items.
