Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the PropertyGrid.SelectedGridItemChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type PropertyGrid named PropertyGrid1. Then ensure that the event handler is associated with the PropertyGrid.SelectedGridItemChanged event.

private void PropertyGrid1_SelectedGridItemChanged(Object sender, SelectedGridItemChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "NewSelection", e.NewSelection );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OldSelection", e.OldSelection );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "SelectedGridItemChanged Event" );
}

Private Sub PropertyGrid1_SelectedGridItemChanged(sender as Object, e as SelectedGridItemChangedEventArgs) _ 
     Handles PropertyGrid1.SelectedGridItemChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "NewSelection", e.NewSelection)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "OldSelection", e.OldSelection)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"SelectedGridItemChanged Event")

End Sub
