Sorry, I was incorrect.  It seems that the CellContextProvider class for this is internal.  You should be able to pass in null for that parameter anyway, though if you need to solve formulas you could probably implement the IConditionContextProvider interface yourself and return the cell of the column as the Context.  As for the value, you should be using the cell's value if you aren't doing anything to modify what's shown to the user (i.e. DataFilter, ValueList, etc).

I do that,and then all fonts are white... Here's the Code for my DrawFilter.

'Dim a variabl to hold the cell
        Dim aCell As UltraGridCell
        Dim aRow As UltraGridRow

        Select Case drawPhase
            Case drawPhase.BeforeDrawForeground
                aRow = drawParams.Element.SelectableItem

                If aRow.Selected Then
                    If (Not aRow.Band.Columns(0).ValueBasedAppearance Is Nothing) Then
                        Dim appData As AppearanceData
                        Dim requestedProps As AppearancePropFlags
                        Dim clsconditionValueAppearance As ConditionValueAppearance

                        appData = New AppearanceData()
                        requestedProps = AppearancePropFlags.AllRender

                        clsconditionValueAppearance = aRow.Band.Columns(0).ValueBasedAppearance 'It's always the first column

                       clsconditionValueAppearance.ResolveAppearance(appData, requestedProps, aRow.Cells(0).Value, nothing)                      

                       drawParams.AppearanceData.ForeColor = appData.ForeColor

                    End If

                End If
        End Select

It is hard to say just based on this code what the problem could be.  Are you saying that regardless of what the cell value is, the appData.ForeColor is white?  Could you attach a small sample to your post, or perhaps paste the condition that you're using as well, and perhaps what data should match it?

 That's right. I have three Formula conditions attached to each cell in a specific Rows. All these conditions refer to other fields' values to determine whether they should paint themselves red/green (or stay black).

 The conditions work great but I get white foreground on every highlighted cell whether the conditions match true or not.

 Hope this helps.

I think that your best bet in this case is to do what I mentioned in a previous post and created your own class that derives from IConditionContextProvider for each cell and use that in the call to ResolveAppearance.  For the Context property you should return the specific cell that is associated with that column.

     Private Class CellContextProvider
        Implements Infragistics.Win.IConditionContextProvider

        Dim cell As UltraGridCell

        Public Sub New(ByRef cell As UltraGridCell)
            Me.cell = cell
        End Sub

        Public ReadOnly Property Context() As Object Implements Infragistics.Win.IConditionContextProvider.Context
            Get
                Return Me.cell
            End Get
        End Property

    End Class

 Hopefully this fixes it for you.

 That did it! Thanks!
