How can I coloring an empty cell in a bounded datagridview?

[Luc001]

Like the title says, I'm trying to coloring an empty cell in bounded datagridview.
I've got this code to coloring a cell with specitic value and is working well.
This code is in the DatagridviewCellFormattingEventargs.

If e.ColumnIndex = 5 AndAlso e.Value <= Date.Now.ToShortDateString Then
              e.CellStyle.ForeColor = Color.DarkGreen
              e.CellStyle.Font = New Font("Adobe Caslon Pro", 11, FontStyle.Bold)
End If

How can I change this code that in the same column and the cell is empty the backgroundcolor becomes red?

Thanks in advance.

From memory you set the background color instead of the forecolor. I'm on my machine without VB.net so I won't check this out for quite some time.

rproffitt that is not what I meant.
The code about te Forecolor is working great. The text is coloring Darkgreen.
What I want is, if there is no text inside a cell in the same column the background color of those cells will be Red.

Again from memory for the reason given, I recall setting the background color even if there is no text in a cell. You can also do more research on this but I do recall doing this before and it was just one thing. However given the half dozen versions of vb.net maybe that was then and now is now?

Found a solution.
Here is my code:

   If e.ColumnIndex = 5 AndAlso Len(e.Value) > 0 Then

            e.CellStyle.BackColor = Color.FromArgb(235, 255, 238)
            e.CellStyle.ForeColor = Color.FromArgb(0, 100, 50)
            e.CellStyle.Font = New Font("Adobe Caslon Pro", 12, FontStyle.Italic)

        ElseIf e.ColumnIndex = 5 AndAlso Len(e.Value) <= 0 Then

            e.CellStyle.BackColor = Color.FromArgb(175, 255, 255)

        End If

Thanks for helping.

Use this to Format a "Rnage" of cells:

Function Cell_Font(SHEET as Worksheet, Rng, _
                     Optional Bold As Boolean = False, _
                     Optional Italic As Boolean = False, _
                     Optional Underline As XlUnderlineStyle = xlUnderlineStyleNone)
    ' Set indicated Cell Font.
    ' 1/31/17 Created. WML
    ' 1/28/21 Reworked. WML

    Prog = "Cell_Font"

    Sheet_Name = SHEET.Name

    SHEET.Range(Rng).Select
        Selection.Font.Bold = Bold
        Selection.Font.Italic = Italic
        Selection.Font.Underline = Underline

End Function ' Cell_Font()
