  Hi,

  From what I remember you would use a callback mechanism. To accomplish this task, do the following:

  - Define the ComboBoxSettings.CallbackRouteValues property to provide ComboBox with actual data;
  - Call the ASPxClientComboBox.PerformCallback method to perform a round-trip to the server.

  There is a published similar solution in this example:

  MVC ComboBox Extension - Cascading Combo Boxes

  Hope this helps.

  Regards,

  D

  Hi amerta,

  Do you mean you want to implement the function with the finite scroll?

  Like the picture below:

  

  If so,you could refer to this demo in Official website：

  https://demos.devexpress.com/MVCxDataEditorsDemos/Editors/ComboBox

  Or you could move to a professional forum about DevExpress:
