Hi

I have never used a class before but thought that it might be appropriate for what I need to do. I have 50 DataGridViews where I need to color the alternate rows using the code below. Now I assume that the first thing to do would be to add a Class module then how would I parse in the DataGridView name given that two of the same names may exist on different forms?

Thanks

Public Class Class1

    Sub ColorDGV(ByVal oDataGridView As DataGridView)
        Dim D As DataGridView = oDataGridView
        For i As Integer = 0 To D.Rows.Count - 1

            If i Mod 2 = 0 Then
                D.Rows(i).DefaultCellStyle.BackColor = Color.LightGray
                'D.Rows(i).DefaultCellStyle.ForeColor = Color.White
            Else
                'D.Rows(i).DefaultCellStyle.BackColor = Color.FromArgb(74, 74, 74)
            End If

        Next i

    End Sub

End Class

There's no need to create another class, DGV already has what you need.
The simpliest way:

MyDataGridView.RowsDefaultCellStyle.BackColor=Color.LightGray
MyDataGridView.RowsDefaultCellStyle.ForeColor=Color.White
MyDataGridView.AlternatingRowsDefaultCellStyle.BackColor=Color.FromArgb(74, 74, 74)
MyDataGridView.AlternatingRowsDefaultCellStyle.ForeColor=[Another colour you prefer]

If you want to enhance the DVG,
use the sintax:

Public Class MyDVGClass
inherits DataGridView
[...]
end Class

to declare the class.
