This is a Delphi project, but I suspect DevExpress’s component works similar for Delphi and .NET.

I have a DevExpress GridDBTableView, when selecting a cell in one of the column, I want a LookupComboBox to show up, where user can select an item, and the value gets display in the table cell. Simple.

  • I’ve set the column’s Properties set to ‘LookupComboBox’.
  • I have ListColumns setup with ‘LocationName’ and ‘QuantityOnHand’.
  • ListSource is set to a datasource that’s linked a dataset of ‘LocationID’, ‘LocationName’, and ‘QuantityOnhand’.
  • ListFieldNames is set to ‘LocationName;QuantityOnHand’

When I click on the cell, the combo box shows up with locations for me to choose, but when I choose a location, the table cell doesn’t show the location name. In fact, I can’t type anything in the cell.

What am I missing?

Ideally, I would like to be able to select a location from the combo box, the location name shows up in the table cell, and I can somehow store the corresponding LocationID that was selected.

    I think that you should also set the column’s Properties.KeyFieldName property to the KeyField of the Lookup DataSource. In this case, everything should work properly.
