Test Specific column of current row

[dsk96m]

On my form I have added items from my dataset. In my code, I want to test if a specific item in that current row is null or not. I am not sure how to go about this. Do I use the bindingsource or table adapter? I am looking for something like:

if flightplanbindingsource.columnname is null then

obviously the above is not correct, but I am wondering how to do it. Any help would be appreciated.
Thanks

Got it. Might not me the best way, but it works

        Dim flightplanRowView = DirectCast(FlightplanBindingSource.Current, DataRowView)
        Dim flightplanRow = DirectCast(flightplanRowView.Row, FlightTestApp2DataSet.flightplanRow)

        If flightplanRow.Istakeoff_time_actualNull Then
            Me.Takeoff_time_actualDateTimePicker.Value = Me.Takeoff_time_plannedDateTimePicker.Value
        End If
