Property Value

Type: System.Int32
The zero-based index of the selected row in a GridView control. The default is -1, which indicates that no row is currently selected.

ExceptionCondition
ArgumentOutOfRangeException

The SelectedIndex property is set to a value less than -1.

Use the SelectedIndex property to determine the index of the currently selected row in a GridView control. You can also use this property to programmatically select a row in the control. To clear the selection of a row, set this property to -1. The appearance of the currently selected row can be customized by using the SelectedRowStyle property. To access the currently selected row, use the SelectedRow property.

The following example demonstrates how to use the SelectedIndex property to select the second row in a GridView control when the control is initially displayed.
