The Event Handler Page: Standard Cube

On the Event Handler page set the handler for extending standard cube capabilities. The page is available only in the web application. A Fore class implemented in the unit or assembly is used a handler.

To connect an event handler to a cube, go to the Event Handler page in the standard cube creation wizard:

To connect an event handler:

Select the unit or assembly in the Select Object drop-down list. To quickly search for an object, start typing its partial or full name in the search string.

Select the event handler in the Event Handler drop-down list.

After executing the operations the event handler is connected to the cube.

To disconnect the event handler, click the Delete button in the Event Handler drop-down list.

To be able to connect a handler to a cube, it should be a class inherited from the ICubeSaveMatrixCallback interface and have the following signature:

Public Class <handler_name>: Object, ICubeSaveMatrixCallback
    // event before saving data to cube
    Public Sub OnBeforeSave(callbackSaveArg: ICubeCallbackBeforeSaveArgument);
    Begin
        ...
    End Sub OnBeforeSave;

    // event after saving data to cube
    Public Sub OnAfterSave(callbackSaveArg: ICubeCallbackSaveArgument);
    Begin
        ...
    End Sub OnAfterSave;
End Class <handler_name>;

To provide correct handler work, add links to the the Cubes, Matrix, and Metabase system assemblies.
