ColumnClickEventArgs 类

定义

ColumnClick 事件提供数据。Provides data for the ColumnClick event.

public ref class ColumnClickEventArgs : EventArgs
public class ColumnClickEventArgs : EventArgs
type ColumnClickEventArgs = class
    inherit EventArgs
Public Class ColumnClickEventArgs
Inherits EventArgs
继承
ColumnClickEventArgs

示例

下面的代码示例演示如何使用此类型。The following code example demonstrates the use of this type. 在此示例中, 事件处理程序报告ColumnClick事件的发生。In the example, an event handler reports on the occurrence of the ColumnClick 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 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ColumnClick事件相关联。Then ensure that the event handler is associated with the ColumnClick event.

private void ListView1_ColumnClick(Object sender, ColumnClickEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Column", e.Column );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ColumnClick Event" );
}
Private Sub ListView1_ColumnClick(sender as Object, e as ColumnClickEventArgs) _ 
     Handles ListView1.ColumnClick

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

End Sub
