    I'm having a database of million records and I must use paging at sql level to reduce the traffic.

    The solution works fine with RadGrid where I can set the Grid.VirtualItemCount = total row count.

    However, RadTreeList does not support that property. Could you explain the reason and give me a work around?

    Hi Robin,

    RadTreeList there is no VirtualItemCount property. However, if you want to improve the performance of the control, you can use the Load on Demand functionality.

    Hi Pavlina,

    I've been using LoadOnDemand for the nested level.

    However, it does not work on the top level. Since we can not set a dummy value to TreeList total row count, we must query all data at top level so that the TreeList can display the Paging correctly.

    May Telerik take into account this issue and add this feature in future release?
