Hello,

I have been looking into your question and my suggestion is using the InitializeRow event that is raised once per row that has been created in the WinGrid. Each time it is raised, you will have an opportunity to access the current row that is being passed through the event arguments and after checking the "LadestelleNr" column value to mark the row per your requirement. I created a small sample application in order to demonstrate how such behavior could be achieved. For the purposes of the example, I marked the required row like setting its BackColor to Yellow.

Private Sub ultraGrid1_InitializeRow(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeRowEventArgs) Handles UltraGrid1.InitializeRow
        If Int32.Parse(e.Row.Cells("LadestelleNr").Value.ToString()) = 5 Then
            e.Row.Appearance.BackColor = Color.Yellow
        End If
    End Sub

 More information about the InitializeRow event could be found here.

Please test the attached below sample on your side and let me know if I may be of any further assistance.
