DataColumnChangeEventHandler Delegate

Represents the method that will handle the ColumnChanging event.

[Visual Basic]
<Serializable>
Public Delegate Sub DataColumnChangeEventHandler( _
   ByVal sender As Object, _
   ByVal e As DataColumnChangeEventArgs _
)
[C#]
[Serializable]
public delegate void DataColumnChangeEventHandler(
   object sender,
   DataColumnChangeEventArgs e
);
[C++]
[Serializable]
public __gc __delegate void DataColumnChangeEventHandler(
   Object* sender,
   DataColumnChangeEventArgs* e
);

[JScript] In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters [Visual Basic, C#, C++]

The declaration of your event handler must have the same parameters as the DataColumnChangeEventHandler delegate declaration.

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

Remarks

When you create a DataColumnChangeEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, until you remove the delegate. For more information about delegates, see Events and Delegates.

Note   The declaration of your event handler must have the same parameters as the DataColumnChangeEventHandler delegate declaration.
