Hi again (I'm asking quite a few questions today)
I've noticed that whilst running RIA with OA, the total entity count does not quite return correctly.


e.g. I have my Domaindatasource_loadingdata event do this:
e.Query.IncludeTotalCount = true;

But no matter what I do, it always returns the total entitycount==entitycount
(e.g. If i query 3/100 , it says the total is 3 rather then 100)



(This feature works fine on ADO, but no on AO, both using an MS SQL express db)
(With out the total entity count, the paging, max page count will always be wrong, which causes other issues as well)
(*edit* Also, it does not cache correctly, e.g. from page 1, goto page 2 then 3, then back to 2, it should be cached but it isn't, I suspect this is related to the total entity count thou, as page 1 seems to cache fine)

Hi Alexander Sun,

We indeed had some problems in the area of the Total count property. Can you please download our latest version and see if your problem is fixed there. We look forward to your replay.

I just downloaded version

Telerik_OpenAccess_ORM_2010_1_624_dev

And the issue is still present (Namely, Totalentitycount = entity count, instead of ACTUAL total entity count)

And I'm using loadsize defined in the XAML's domain data source (loadsize 10, pagesize 5 both on DDS, and total entity count is 10, instead of ~29)

Just some extra info,

It turns out the total entity count is only PARTIALLY broken. In that, by default, my RIA service is sorted by date, and the radgridview its bound to is "unsorted". But if I sort the grid view, then it will give the correct total entity count. (And if I make it unsorted again, it will give the incorrect count)
