HtmlElement.MouseUp Event
Occurs when the user releases a mouse button.
Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can cancel the default action for a MouseUp event on an element by setting the ReturnValue property of the HtmlElementEventArgs class to true.
A MouseUp event on an element will also occur on that element's parent elements and on the HtmlDocument class itself, unless you set the BubbleEvent property of the HtmlElementEventArgs class to true.
For more information about the difference between canceling event bubbling and canceling the default action on an event, see About the DHTML Object Model.
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the MouseUp event. This report helps you to learn when the event occurs and can assist you in debugging. 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.
To run the example code, paste it into a project that contains an instance of type HtmlElement named HtmlElement1. Then ensure that the event handler is associated with the MouseUp event.
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" ); }
