Using the AddingDataRow event

In This Topic

The AddingDataRow event is raised when a new data row is about to be added to the grid. It allows you to provide data manually to the row's cells or to modify the data being read from the data source.

Basic steps - C#

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

Obtain a reference to a GridControl object.
Subscribe to the AddingDataRow event of the GridControl object using the AddingDataRowEventHandler 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 AddingDataRow event, the following steps must be performed:

Obtain a reference to a GridControl object.
Subscribe to the AddingDataRow event of the GridControl 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.
