SqlCeDataAdapter.RowUpdating Event

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

Occurs during Update before a command is executed against the data source. The attempt to update is made, so the event fires.

[C#]
public event SqlCeRowUpdatingEventHandler RowUpdating;
[C++]
public: __event SqlCeRowUpdatingEventHandler* RowUpdating;

[JScript] In JScript, you can handle the events defined by a class, but you cannot define your own.
