Grouping a VirtualQueryableCollectionView

[Todd Millett]

I have a IEnumerable of a custom class which i am getting from the server. I want to group the data based on a particular column in that custom class same as can be done with any IEnumerable collection like : results.GroupBy(i => i.GroupName == "Test")
How can that be done using VirtualQueryableCollectionView?
Actually my requirement is to get those groups and then based on the number of groups i have to create that many tabs.
Also will the single VirtualQueryableCollectionView work with different tabs, in terms of loading data based on scrolling and stuffs?

Hi,

 Grouping is not supported with VirtualQueryableCollectionView.

Not even from codebehind? Or are there any alternatives?

So does it mean that if i use VirtualQueryableCollectionView then I cannot show grouping on the UI? even if the data is getting group from the server?

Can you please let me know this, as we have a very imp decision to make on this...

Actually this is a feature which is the most important thing missing in RadGridView and VirtualQueryableCollectionView. Are there any plans to implement or it anytime in the near future. You are right todd, even a workaround would do it, otherwise the grid seems incomplete.

Anyone have a status on this? This is kind of a deal breaker...

Hello,

 Grouping a VirtualQueryableCollectionView is possible however only locally on the client since there is no way so far to transfer groups from the server to the client. Even WCF RIA services grouping is fake - just plain sorting.

Do you have a quick example of this grouping on the client side?

Thanks,
