Parameters

filterViewModel

The IFilterViewModel whose FilterMembers hierarchy will be expanded.

levelUniqueName

The unique name of the level which specifies the depth of FilterMembers hierarchy will be expanded up to.

refreshGrid

Boolean value indicating whether to execute an additional task which calls the RefreshGrid method.

Return Value

The System.Threading.Tasks.Task which completes when all members of FilterMembers hierarchy are loaded and set to expanded up to the specified level depth.

Remarks

To preserve legacy behavior, the value of the refreshGrid parameter resolves to false when no value has been specified.

When true is specified as the value of the refreshGrid, a reference to this additional task is returned. This additional task is executed as a continuation, on the same thread as the antecedent Task.
