Control.MouseClick Control.MouseClick Control.MouseClick Control.MouseClick Event

Definition

Occurs when the control is clicked by the mouse.

public:
 event System::Windows::Forms::MouseEventHandler ^ MouseClick;
public event System.Windows.Forms.MouseEventHandler MouseClick;
member this.MouseClick : System.Windows.Forms.MouseEventHandler 
Public Custom Event MouseClick As MouseEventHandler 

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the MouseClick 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 a type that inherits from Control, such as a Button or ComboBox. Then name the instance Control1 and ensure that the event handler is associated with the MouseClick event.

private void Control1_MouseClick(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(), "MouseClick Event" );
}
Private Sub Control1_MouseClick(sender as Object, e as MouseEventArgs) _ 
     Handles Control1.MouseClick

    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(),"MouseClick Event")

End Sub

Remarks

Depressing a mouse button when the cursor is over a control typically raises the following series of events from the control:

  1. MouseDown event.

  2. Click event.

  3. MouseClick event.

  4. MouseUp event.

For this to occur, the various events cannot be disabled in the control's class.

Two single clicks that occur close enough in time, as determined by the mouse settings of the user's operating system, will generate a MouseDoubleClick event instead of the second MouseClick event.

Important

Click events are logically higher-level events of a control. They are often raised by other actions, such as pressing the ENTER key when the control has focus.
