The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the Format 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 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 a type that inherits from ListControl, such as a ComboBox or ListBox. Then name the instance ListControl1 and ensure that the event handler is associated with the Format event.
private void ListControl1_Format(Object sender, ListControlConvertEventArgs e) { System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder(); messageBoxCS.AppendFormat("{0} = {1}", "ListItem", e.ListItem ); messageBoxCS.AppendLine(); messageBoxCS.AppendFormat("{0} = {1}", "Value", e.Value ); messageBoxCS.AppendLine(); messageBoxCS.AppendFormat("{0} = {1}", "DesiredType", e.DesiredType ); messageBoxCS.AppendLine(); MessageBox.Show(messageBoxCS.ToString(), "Format Event" ); }
