LabelEditEventArgs Class

Provides data for the ListView.BeforeLabelEdit and ListView.AfterLabelEdit events.

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

public class LabelEditEventArgs : EventArgs

A LabelEditEventArgs specifies the index and caption of a ListViewItem and the caption after it has been edited by the user. This class also provides a CancelEdit property. You can use this property in a ListView.BeforeLabelEdit event handler to prevent the user from editing the label. You can also use it in an ListView.AfterLabelEdit event handler to revert the change, returning the label it to its original value. This is useful when you want to validate user input before committing the change.

NoteNote:

Because the ListView.AfterLabelEdit event takes place before the label edit is committed, calling the ListView.Sort method in a handler for this event will sort the item using the original value.

The following code example demonstrates handling the ListView.BeforeLabelEdit event and using the Item and CancelEdit properties. To run the example, paste the following code in a form containing a ListView control named ListView1 and populated with at least 3 items. Ensure all events are associated with their event-handling methods.

   	private void ListView1_BeforeLabelEdit(object sender, 
		System.Windows.Forms.LabelEditEventArgs e)
	{
		// Allow all but the first two items of the list to  
		// be modified by the user. 
		if (e.Item<2)
		{
			e.CancelEdit = true;
		}
	}
The following code example demonstrates handling the ListView.BeforeLabelEdit event
and using the EditLabelEventArgs.Item and CancelEdit properties. 
To run the example, paste the following code in a form containing a ListView control named ListView1 and populated with at least 3 items.
