Use the BackColor property to specify the node's background color. Use the ForeColor property to specify the node's foreground color. Use the ForeColorValue property to specify the node's value foreground color.

The following sample changes the node's value background color while cursor hovers the control:

Dim nOld As EXMLGRIDLibCtl.Node
Private Sub XMLGrid1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    With XMLGrid1
        Dim n As EXMLGRIDLibCtl.Node, h As EXMLGRIDLibCtl.HitTestEnum
        h = .HitTest(X / Screen.TwipsPerPixelX, Y / Screen.TwipsPerPixelY, n)
        If Not nOld Is n Then
            If Not nOld Is Nothing Then
                nOld.ClearBackColorValue
                nOld.ClearForeColorValue
            End If
            If Not h = 0 Then
                n.BackColorValue = vbGreen
                n.ForeColorValue = vbBlue
            End If
        End If
        Set nOld = n
    End With
End Sub
