Using the EnteringEdit event

The EnteringEdit event is raised before editing a cell. It provides the possibility to prevent the cell from being edited and to change the CellEditorManager that will be used to edit the cell.

Basic steps - C#

To subscribe to the EnteringEdit event, the following steps must be performed:

Obtain a reference to a Cell object.
Subscribe to the EnteringEdit event of the Cell object using the EnteringEditEventHandler delegate class
Create a new method that will handle the events that are raised.
Place the desired code in the newly created event handler.

Basic steps - VB.NET

To subscribe to the EnteringEdit event, the following steps must be performed:

Obtain a reference to a Cell object.
Subscribe to the EnteringEdit event of the Cell object using the AddHandler/AddressOf keywords.
Create a new method that will handle the events that are raised.
Place the desired code in the newly created event handler.

Demonstration

This example assumes that you are in a Windows application.
