DataColumnChangeEventHandler Delegate

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.

Parameters [Visual Basic, C#, C++]

The declaration of your event-handling method must have the same parameters as the DataColumnChangeEventHandler delegate declaration.

The source of the event.
A DataColumnChangeEventArgs that contains the event data.

Remarks

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. For more information about delegates, see TBD
