Hello,

for my WPF application I need a DataGrid which realizes real Data Virtualization and not only UI Virtualization.

For the first time I've read your documentation. For Data Virtualization you are using VirtualQueryableCollectionView.

Look at: http://www.telerik.com/help/wpf/gridview-populating-datavirtualization.html

In my application the data comes from a MS SQL Server Database. What I need is to load only the data

from the database into the memory which are displayed in the DataGrid. If I'm scrolling in the DataGrid

the old data should be removed from the memory. If scrolling will be stopped only the data should be

in the memory which are displayed in the DataGrid.

Is that possible with your Data Virtualization ?

If I'm using your Data Virtualization does your built-in sorting, built-in filtering, built-in grouping

work without any limitations ? For example does your built-in filtering work on the whole data (for example a table

of my database) without loading all the data into the memory ?

Is it possible to edit data in the DataGrid or to add/remove a data row in the DataGrid if I'm using your Data Virtualization

Thank you for your answers.

Best regards,

Florian Schwarz
