CheckedListBox.Click Event

Occurs when the user clicks the CheckedListBox control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[BrowsableAttribute(true)]
public event EventHandler Click

The Click event passes an EventArgs to its event handler, so it only indicates that a click has occurred. If you need more specific mouse information (such as the button, number of clicks, wheel rotation, or location), use the MouseDown and MouseUp events, which pass a MouseEventArgs to the event handler.

A double-click is determined by the mouse settings of the user's operating system. The user can adjust the amount of time that can pass between clicks during a double-click of a mouse button. The Click event is raised every time the user double-clicks a control. For example, if you have event-handling methods for the Click and DoubleClick events of a form, the events are raised when the form is double-clicked and both event-handling methods are called. If the user double-clicks a control that does not support the DoubleClick event, the Click event might be raised twice.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the Click 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 CheckedListBox named CheckedListBox1. Then ensure that the event handler is associated with the Click event.


private void CheckedListBox1_Click(Object sender, EventArgs e) {

   MessageBox.Show("You are in the CheckedListBox.Click event.");

}
