ListView.ItemCheck Event

Occurs when the check state of an item changes.

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

JScript does not support events.

The CheckBoxes property must be set to true in order for check boxes to be displayed next to each item in the ListView control. The ItemCheck event occurs when the check state of an item changes or when the CheckBoxes property is set to true. You can create an event handler for the ItemCheck event to perform tasks such as changing the state of an item's icon or another application-specific task each time an item is checked in the ListView control.


If the Visible property of the ListView control is set to false at the time the control is created, the ItemCheck event is not raised. Once the control is visible, the event is raised regardless of the state of the Visible property.

For more information about handling events, see Consuming Events.

The following code example demonstrates a checked ListView control that handles the ItemCheck event. The method uses the ItemCheckEventArgs.CurrentValue and ItemCheckEventArgs.Index properties to retrieve and tally the price of the menu items selected. To run this example, paste the following code into a form containing a ListView named ListView1 and a TextBox named Textbox1. Call the InititalizeListView method from the form's constructor or Load method. Ensure that the ItemCheck event is associated with the event handler in this example.

No code example is currently available or this language may not be supported.
