I was just implementing some NVL's into my BO and thought I would like to fill them all asynchronously.
I copied the logic from the InventoryDemo but decided I wanted them async regardless of Silverlight or not. However the step to just return the cached list doesn't work outside CSLALight because the required DataPortalResult method is not public.
Is that intentional and I shouldn't be doing what I want to do? Thanks

public static void GetProductCategories(EventHandler<DataPortalResult<ProductCategories>> callback)
{
if (_cache != null)
{
callback(null, new
DataPortalResult<ProductCategories>(_cache, null, null));
}
else
{
var dp = new DataPortal<ProductCategories>();
dp.FetchCompleted += (o, e) =>
{
_cache = e.Object;
callback(dp, e);
};
dp.BeginFetch();
}
}
