Evento ListView.ColumnWidthChanged

 

Data di pubblicazione: ottobre 2016

Si verifica quando la larghezza di una colonna viene correttamente modificata.

Spazio dei nomi:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public event ColumnWidthChangedEventHandler ColumnWidthChanged

This event will not occur if the column width change is canceled in the E:System.Windows.Forms.ListView.ColumnWidthChanging event

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the E:System.Windows.Forms.ListView.ColumnWidthChanged 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 Overload:System.Windows.Forms.MessageBox.Show with Overload:System.Console.WriteLine or appending the message to a multiline T:System.Windows.Forms.TextBox.

To run the example code, paste it into a project that contains an instance of type T:System.Windows.Forms.ListView named ListView1. Then ensure that the event handler is associated with the E:System.Windows.Forms.ListView.ColumnWidthChanged event.

private void ListView1_ColumnWidthChanged(Object sender, ColumnWidthChangedEventArgs e) {

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