We are aware of a filtering problem using the 2016.3.914 version of Telerik controls related to the AutoPostBackOnFilter property.
The issue can be observed when a grid column has this property set to True. The filtering action may work for the first time, but does not work for any consequent attempts with the same or another column.
iltering with CheckList and Combined mode and server-side binding for the ListBox:
'Value' is not supported filter function for GridBoundColumn. Custom filter functions must be handled in the ItemCommand event handler. Set e.Canceled=true to stop the built-in filtering.
