ListView.ColumnWidthChanged ListView.ColumnWidthChanged ListView.ColumnWidthChanged ListView.ColumnWidthChanged Event

定义

在成功更改列的宽度后发生。Occurs after the width of a column is successfully changed.

public:
 event System::Windows::Forms::ColumnWidthChangedEventHandler ^ ColumnWidthChanged;
public event System.Windows.Forms.ColumnWidthChangedEventHandler ColumnWidthChanged;
member this.ColumnWidthChanged : System.Windows.Forms.ColumnWidthChangedEventHandler 
Public Custom Event ColumnWidthChanged As ColumnWidthChangedEventHandler 

示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中, 事件处理程序报告ColumnWidthChanged事件的发生。In the example, an event handler reports on the occurrence of the ColumnWidthChanged event. 此报表可帮助你了解何时发生事件, 并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告多个事件或频繁发生的事件, 请考虑MessageBox.ShowConsole.WriteLine消息替换为多行或将TextBox其追加到多行。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.

若要运行示例代码, 请将其粘贴到包含名为ListView ListView1的类型的实例的项目中。To run the example code, paste it into a project that contains an instance of type ListView named ListView1. 然后, 确保事件处理程序与ColumnWidthChanged事件相关联。Then ensure that the event handler is associated with the 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" );
}
Private Sub ListView1_ColumnWidthChanged(sender as Object, e as ColumnWidthChangedEventArgs) _ 
     Handles ListView1.ColumnWidthChanged

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

End Sub

注解

如果在ColumnWidthChanging事件中取消了列宽更改,则不会发生此事件This event will not occur if the column width change is canceled in the ColumnWidthChanging event
