Update sorting in grid when data has changed

[Licenses]

Hello,

I have a telerik radgridview that is bound to a QueryableDomainServiceCollectionView in a ViewModel. The QueryableDomainServiceCollectionView has a sortdescriptor on a field called SequenceNumber. The user can change the sequencenumber of the selected item, by clicking up- and downbuttons. When I save the context after an item has been moved, the gridview is refreshed and the item has indeed moved to the correct position.

Is there a way to re-apply sorting without having to perform a submit of the context? Back in the old days, when we were working with ObservableCollections, we just had to notify the gridview via a PropertyChanged event on the observable collection. How do i do this with a QueryableDomainServiceCollectionView? PropertyChanged event doesn't seem to do the trick.

Thank you,
Sodi

Hello Sodi We,

Can you try calling the Rebind method of the grid and see how it goes?

Another option would be to remove and re-add the SortDescriptor. This should resort the grid.

Let us know if these do not help.

These two options don't seem to do the trick. I think the problem is that as soon as the context has changes, rebinding the grid, or re-sorting doesn't seem to work. Also important to state is that the grid is a paged grid with a RadDataPager bound to the same QueryableDomainServiceCollectionView.

Any other options?

Kind regards,

I've also tried to set the QueryableDomainServiceCollectionView to which the grid is bound to null, and then set it back to its old value and re-applying sorting, filtering and grouping. Still no success...

Hi Sodi We,

That is weird. In this case, could you please open a separate support ticket and attach a sample project with your exact configuration. I will try to come up with some kind of workaround for your case.

Thanks in advance.

All the best,
