Before anyone else might get led up the garden path......I wasted a few days on this!

Devexpress Xtragrid using LinqServerModeSource is READ ONLY.......

You won't be able to do anything but browse your data....

Pity. And I've been told they have no intention to make it updateable in the future either....

bah humbug

Well, how would you expect the grid to be able to save the data? Linq is a fetching technique. If you're fetching new types, these aren't saveble.

Same as usual (using the same methods available to the grid control ie OnUpdate etc) ...

(Edit)

They actively disable these edit functions when in linq mode

I think because it's undoable to save the data in many scenario's. So if you want to save entities etc. use our datasourcecontrols instead.

I'm using it in a win app!?

I'm trying to page the records (server mode) as there are hundreds of thousands of records.....

Would it be of use?

And you would like the records to be fetched only when they are displayed because you can't afford to load them all in memory right? DevExpress server mode is based on an interface, it should be possible to implement this interface with llblgen code but although I haven't tried I'm sure it would be hard work to handle all possible sortings, groupings, filterings...

Can you afford to provide a few controls (comboboxes, textboxes) which would allow the user to be a bit more specific about the actually needed records ?

Can you share some code with me. I am also trying to use LLBLGen with the Xtragrid. I am building a winform app and using LLBLGen in adapter mode. I am only going to use the server mode for browsing data.

Youd prob want a project to look at rather than just some code, this helped me when I kicked off:

you may find some more in there....

NEWS: Turns out theyve fixed the grid (can write now) the sly buggers....
