C#

public bool InsertFilterAsync( 
   Infragistics.Olap.Core.Data.Hierarchy hierarchy,
   int index,
   bool update,
   Control control
)

Parameters

hierarchy

The hierarchy to be inserted.

index

Optional ordinal position at which to insert the hierarchy. If no value is specified, the hierarchy is added as the last one on the filter axis.

update

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 AddFilterAsyncCompleted 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 AddFilterAsyncCompleted event does not occur.

control

Optional reference to a Control. If specified, the AddFilterAsyncCompleted 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

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.
