I have been unable to google the right keywords to this hopefully easy
answer.

I bind a combobox:
       With cboOperator
           Dim operator As OperatorDataTable = _company.Operator
           .DataSource = operator
           .DisplayMember = operator.Name.ColumnName
           .ValueMember = operator.OperatorId.ColumnName
       End With

When I run the app, unfortunately, I can still type data into the
combobox. I only want users to be able to select from the populated
list.

Is my only solution to filter out keys on keypress or is there
something much simpler I have missed?

Thanks,
Ross
