Hi

Priyanka,Thank you for the information!I updated the nugets to the latest version. Can you help me please how can I disable scrolling in dropdown-closed state (by default nothing changed)?

Hi SZL,

Please utilize the MouseWheel Event to prevent value changes when scrolling the parent of a sfComboBox in dropdown-closed state by using HandledMouseEventArgs. Please refer the attached sample for your reference. Please let us know if you need any further assistance.
