As mentioned in our documentation article regarding the Data Virtualization
, the virtual collection is designed for ReadOnly purposes and it is not recommended to use it in scenarios where updates are required. You can add/delete items but you will have to work with the VirtualItemCount
property of the VQCV(increase it in case you are adding an item) and rebind the RadGridView as well, which might not be ideal.
var collection =
, DateTime.Now, 45000));
Another approach would be to add/remove items from your source directly and reload the VQCV.
