ToolStripItem.LocationChanged ToolStripItem.LocationChanged ToolStripItem.LocationChanged ToolStripItem.LocationChanged Event


当更新 ToolStripItem 的位置时发生。Occurs when the location of a ToolStripItem is updated.

 event EventHandler ^ LocationChanged;
public event EventHandler LocationChanged;
member this.LocationChanged : EventHandler 
Public Custom Event LocationChanged As EventHandler 


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LocationChanged事件的发生。In the example, an event handler reports on the occurrence of the LocationChanged 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, 请将其粘贴到一个项目中, 该项目包含从ToolStripItem继承的类型的实例, 如ToolStripMenuItem ToolStripButton或。To run the example code, paste it into a project that contains an instance of a type that inherits from ToolStripItem, such as a ToolStripButton or ToolStripMenuItem. 然后命名该实例ToolStripItem1 , 并确保事件处理程序LocationChanged与事件相关联。Then name the instance ToolStripItem1 and ensure that the event handler is associated with the LocationChanged event.

private void ToolStripItem1_LocationChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ToolStripItem.LocationChanged event.");

Private Sub ToolStripItem1_LocationChanged(sender as Object, e as EventArgs) _ 
     Handles ToolStripItem1.LocationChanged

   MessageBox.Show("You are in the ToolStripItem.LocationChanged event.")

End Sub


如果ToolStripItem通过编程修改或通过交互进行更新, 则会引发此事件。This event is raised if the ToolStripItem is updated by either a programmatic modification or through interaction.


更改的Enabled ToolStrip属性不会引发LocationChanged事件。Changing the Enabled property of a ToolStrip does not raise the LocationChanged event. 用特定属性设置引发此事件。Raise this event with specific property settings.
