C#

public bool RemoveFilterAsync( 
   string hierarchyUniqueName,
   bool update,
   Control control
)

Parameters

hierarchyUniqueName

The unique name of the Hierarchy to be removed. If the specified unique name cannot be resolved, a HierarchyNotFoundException exception is thrown.

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 RemoveFilterAsyncCompleted 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 RemoveFilterAsyncCompleted event does not occur.

control

Optional reference to a Control. If specified, the RemoveFilterAsyncCompleted 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.

Return Value

A boolean value indicating whether the method call resulted in any change to the data source. If the specified measure does not exist on the slicer axis, false is returned and no action is taken.

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.
