Gets the old PropertyTab selected.

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

public PropertyTab OldTab { get; }

Property Value

Type: System.Windows.Forms.Design.PropertyTab

The old PropertyTab that was selected.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the PropertyGrid.PropertyTabChanged 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.PropertyTabChanged event.

private void PropertyGrid1_PropertyTabChanged(Object sender, PropertyTabChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "OldTab", e.OldTab );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "NewTab", e.NewTab );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "PropertyTabChanged Event" );
}
