OdbcRowUpdatingEventHandler Delegate

Note: This namespace, class, or member is supported only in version 1.1 of the .NET Framework.

Represents the method that will handle the RowUpdating event of an OdbcDataAdapter.

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

sender
The source of the event.
e
The OdbcRowUpdatingEventArgs that contains the event data.

Remarks

The handler is not required to perform any action, and your code should avoid generating exceptions or allowing exceptions to propagate to the calling method. Any exceptions that do reach the caller are ignored.

Use the handler to process OdbcRowUpdatingEventArgs and to specify how updates are processed. For example, you may opt to skip the update of the current row or skip the update of all remaining rows. Note that the rows are updated in the order that they were received from the data source.

When you create an OdbcRowUpdatingEventArgs 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, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates
