Provides data for the ColumnChanging event.
[Visual Basic] Public Delegate Sub DataColumnChangeEventHandler( _ ByVal sender As Object, _ ByVal e As DataColumnChangeEventArgs _ ) [C#] public delegate void DataColumnChangeEventHandler( object sender, DataColumnChangeEventArgs e ); [C++] public __gc __delegate void DataColumnChangeEventHandler( Object* sender, DataColumnChangeEventArgs* e );
[JScript] In JScript, you can use the delegates in the NGWS frameworks, but you cannot define your own.
The declaration of your event-handling method must have the same parameters as the DataColumnChangeEventHandler delegate declaration.
When you create a DataColumnChangeEventHandler delegate, you identify the method that will handle the vent. To associate the event with your event-handling method, add an instance of the delegate to the event. The event-handling method is called whenever the event occurs, until you remove the delegate.
