GetHierarchiesAsync Method

Sends an asynchronous request to the OLAP server to return a list of all hierarchies available under the currently selected Cube.

Syntax

Visual Basic

'Declaration
 
Public Sub GetHierarchiesAsync( _
   Optional ByVal control As Control _
) 

C#

public void GetHierarchiesAsync( 
   Control control
)

Parameters

control

Optional reference to a Control. If specified, the GetHierarchiesAsyncCompleted event is raised on the thread on which this control's handle was created. This approach makes it possible to access control members directly from the event handler.

Remarks

If this data source has not yet been initialized, calling this method will trigger initialization.

This method returns immediately after issuing the request to the OLAP server so as not to block the calling thread. The actual operation, however, does not occur until the server returns this request, which happens indeterminately.
