public:
 event System::Windows::Forms::MouseEventHandler ^ MouseDown;

Public Custom Event MouseDown As MouseEventHandler

Event Type

MouseEventHandler

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the MouseDown 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 NotifyIcon named NotifyIcon1. Then ensure that the event handler is associated with the MouseDown event.

private void NotifyIcon1_MouseDown(Object sender, MouseEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Button", e.Button );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Clicks", e.Clicks );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Delta", e.Delta );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Location", e.Location );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "MouseDown Event" );
}

Private Sub NotifyIcon1_MouseDown(sender as Object, e as MouseEventArgs) _ 
     Handles NotifyIcon1.MouseDown

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Button", e.Button)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Clicks", e.Clicks)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Delta", e.Delta)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Location", e.Location)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"MouseDown Event")

End Sub
