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

Public Custom Event DragEnd As HtmlElementEventHandler

Event Type

HtmlElementEventHandler

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the DragEnd 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 DragEnd event.

private void HtmlElement1_DragEnd(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(), "DragEnd Event" );
}

Private Sub HtmlElement1_DragEnd(sender as Object, e as HtmlElementEventArgs) _ 
     Handles HtmlElement1.DragEnd

    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}", "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(),"DragEnd Event")

End Sub

Remarks

You can cancel the default action for a DragEnd event on an element by setting the ReturnValue property of the HtmlElementEventArgs class to true.

A DragEnd 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.
