UltraCombo issue

Using an UltraCombo on a deployed dashboard. Combo has LotSelectUpdate list dataset as source and LotNum for ValueMember and DisplayMember and ColumnFilter

the combo is populated in the BeforeDropDown Event
When the arrow is clicked, the entire dataset is shown. the second time it is clicked only the lot number data is shown which is the desired effect

anyone know a way to only show the lot number on first dropdown?

In case anyone comes across this in a search - the resolution is to hide the unwanted columns in the InitializeLayout event
