Hi,
we are facing the problem that we have to implement data virtualization into our existing solutions with the XamDataGrid. In our case we are using the grouping / hierarchical function of the grid a lot.
Therefore I'd like to ask if anyone has implemented such a behaviour for the XamDataGrid and could provide a sample for this. The information how we could use the grouping function in combination with data virtualization would help a lot as well.
Thanks and kind regards,
Thilo
Hi thilo1978,
I am also trying to similar problem that you came across. ie., doing data virtualization with xamDataGrid that has grouping enabled in it.
In my case data updates in realtime in DB which keeps the collection update also. After data virtualization how can I keep the grouping (with summary count) updated.
Your experiences/ideas will greatly help.
Thanks,
Imad.
thanks. But with data virtualization I meant that even the SQL statements retrieve only the rows which are actually required for presentation. In our case we built a 3 tier architecture and the middle and the backend virtualize the data quite well. Now we are in the process to present the data on the client. Therefore the client only gets the number of rows (count) and the requested rows, eg. beween row 100 and row 140.
Kind regards,
Hello Thilo,
The XamDataGrid will virtualize the records by default and will create presenters only for the ones that are currently in view. The rest of them will be generated or reused only when they come into view. Do you have in mind some other kind of virtualization?
