HtmlElement.MouseUp 事件

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

來源:

HtmlElement.cs

當使用者放開滑鼠按鈕時會發生。

public:
 event System::Windows::Forms::HtmlElementEventHandler ^ MouseUp;

public event System.Windows.Forms.HtmlElementEventHandler? MouseUp;

member this.MouseUp : System.Windows.Forms.HtmlElementEventHandler 

Public Custom Event MouseUp As HtmlElementEventHandler 

事件類型

HtmlElementEventHandler

範例

以下程式碼範例展示了此成員的使用方式。 在這個例子中，事件處理者會回報事件 MouseUp 的發生情況。 此報告能幫助您了解事件發生時間，並協助除錯。 若要報告多個事件或頻繁發生的事件，請考慮將MessageBox.Show訊息替換Console.WriteLine為或附加於多行TextBox。

要執行範例程式碼，請將其貼到包含一個 HtmlElement 名為 HtmlElement1的實例的專案中。 然後確保事件處理程式與事件 MouseUp 相關聯。

private void HtmlElement1_MouseUp(Object sender, HtmlElementEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "MouseButtonsPressed", e.MouseButtonsPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ClientMousePosition", e.ClientMousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OffsetMousePosition", e.OffsetMousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "MousePosition", e.MousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "BubbleEvent", e.BubbleEvent );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "KeyPressedCode", e.KeyPressedCode );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "AltKeyPressed", e.AltKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "CtrlKeyPressed", e.CtrlKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ShiftKeyPressed", e.ShiftKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "EventType", e.EventType );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ReturnValue", e.ReturnValue );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "FromElement", e.FromElement );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToElement", e.ToElement );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "MouseUp Event" );
}

Private Sub HtmlElement1_MouseUp(sender as Object, e as HtmlElementEventArgs) _ 
     Handles HtmlElement1.MouseUp

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "MouseButtonsPressed", e.MouseButtonsPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ClientMousePosition", e.ClientMousePosition)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "OffsetMousePosition", e.OffsetMousePosition)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "MousePosition", e.MousePosition)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "BubbleEvent", e.BubbleEvent)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "KeyPressedCode", e.KeyPressedCode)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "AltKeyPressed", e.AltKeyPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "CtrlKeyPressed", e.CtrlKeyPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ShiftKeyPressed", e.ShiftKeyPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "EventType", e.EventType)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ReturnValue", e.ReturnValue)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "FromElement", e.FromElement)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ToElement", e.ToElement)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"MouseUp Event")

End Sub

備註

你可以透過將該類別true的屬性HtmlElementEventArgs設ReturnValue為 來取消該事件的預設動作MouseUp。

MouseUp元素上的事件也會發生在該元素的父元素以及HtmlDocument類別本身，除非你將類別的屬性HtmlElementEventArgs設BubbleEvent為 true。
