Property Value

The value of the selected item in the list control. The default is an empty string ("").

This property returns the Value property of the selected ListItem. The SelectedValue property is commonly used to determine the value of the selected item in the list control. If multiple items are selected, the value of the selected item with the lowest index is returned. If no item is selected, an empty string ("") is returned.

The SelectedValue property can also be used to select an item in the list control by setting it with the value of the item. If no items in the list control contain the specified value, a System.ArgumentOutOfRangeException is thrown.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins Overview.

The following example demonstrates how to use the SelectedValue property to select an item in a ListBox control. Notice that this property can also be used to retrieve the value of the selected item.

No code example is currently available or this language may not be supported.
