As I said, the RadDataBoundListBox
is designed with UI virtualization in mind and you cannot disable it. However, you could use the RealizedItemsBufferScale
property to increase the UI virtualization buffers' size so that more visual containers are realized at once:
this.radDataBoundListBox.RealizedItemsBufferScale = 4.0;
This will make the UI virtualization buffers 4 times the size of the control which will increase the amount of visual containers being realized.
Let me know in case I can further assist you.
