ToolStrip.ItemAdded ToolStrip.ItemAdded ToolStrip.ItemAdded ToolStrip.ItemAdded Event

定義

發生於將新的 ToolStripItem 加入 ToolStripItemCollection 時。Occurs when a new ToolStripItem is added to the ToolStripItemCollection.

public:
 event System::Windows::Forms::ToolStripItemEventHandler ^ ItemAdded;
public event System.Windows.Forms.ToolStripItemEventHandler ItemAdded;
member this.ItemAdded : System.Windows.Forms.ToolStripItemEventHandler 
Public Custom Event ItemAdded As ToolStripItemEventHandler 

範例

下列程式碼範例示範如何使用這個成員。The following code example demonstrates the use of this member. 在此範例中, 事件處理常式會報告ItemAdded事件的發生次數。In the example, an event handler reports on the occurrence of the ItemAdded event. 此報表可協助您瞭解事件發生的時間, 並可協助您進行調試。This report helps you to learn when the event occurs and can assist you in debugging. 若要報告多個事件或經常發生的事件, 請考慮MessageBox.ShowConsole.WriteLine取代為, 或將訊息附加TextBox至多行。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.

若要執行範例程式碼, 請將它貼入包含名為ToolStrip ToolStrip1之類型實例的專案中。To run the example code, paste it into a project that contains an instance of type ToolStrip named ToolStrip1. 然後確定事件處理常式與ItemAdded事件相關聯。Then ensure that the event handler is associated with the ItemAdded event.

private void ToolStrip1_ItemAdded(Object sender, ToolStripItemEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ItemAdded Event" );
}
Private Sub ToolStrip1_ItemAdded(sender as Object, e as ToolStripItemEventArgs) _ 
     Handles ToolStrip1.ItemAdded

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

End Sub
