Changed Event (ExGrid) | Exontrol Docs

The Changed event occurs after the user has changed the content of a cell. The Change event notifies your application that the user changes the cell's content. The Change event is fired when the CellValue property is changed.

The following edit-related events are triggered in this sequence:

Edit event, This event is raised before the editing process begins. It allows you to prevent the cell from being edited by setting the Cancel parameter to True.
EditOpen event, Triggered once the editing process starts and the editor is displayed. The Editing property returns the handle of the internal editor window being used.
Change event, Fired just before the cell's content is about to change. The NewValue parameter contains the new value that will be assigned to the cell, while the CellValue property holds the current value. If the control is linked to a database, note that the corresponding database field remains unchanged at the time the Change event is triggered.
Changed event, Occurs after the user has successfully changed the content of the cell. The CellValue property now reflects the updated value. If the control is linked to a database, the corresponding field is updated, so the new value is available during the Changed event.
EditClose event, Raised when the cell editor is closed and no longer visible.

		Type	Description
		Item as HITEM	A long expression that determines the item's handle. If the Item parameter is 0, and the ColIndex property is different than zero, the ColIndex indicates the handle of the cell where the state is changed.
		ColIndex as Long	A long expression that indicates the column's index, if the Item parameter is not zero, a long expression that indicates the handle of the cell if the Item parameter is 0.
