'Declaration Public Sub ExpandAxisTupleMemberAsync( _ ByVal axisType As AxisType, _ ByVal tupleIndex As Integer, _ ByVal memberIndex As Integer, _ Optional ByVal update As Boolean, _ Optional ByVal control As Control _ )
Optional boolean value indicating whether to update the data source immediately.
The default value is true, which causes the request to be sent to the OLAP server immediately, and raises the ExpandAxisTupleMemberAsyncCompleted event when the server's response has been received.
If false is specified, the request is not sent to the server until the UpdateAsync method is called.
Note that when false is specified, the ExpandAxisTupleMemberAsyncCompleted event does not occur.
If the specified member is not expandable, or is currently expanded, this method returns without incident.
This method returns immediately after issuing the request to the OLAP server so as not to block the calling thread. The actual expansion, however, does not occur until the server returns this request, which happens indeterminately.
