DataGridView Scroll show columns over others

I have a datagridview, and when i use scrollbar the columns shown over the others, like this image:

i have tried DoubleBuffered like that:

DoubleBuffered

1- i created a module named "DoubleBuffer.vb"

2- i add that code in it:

Imports System
Imports System.Reflection
Imports System.Windows.Forms
Module DoubleBuffer
Public Sub DoubleBuffered(ByVal dgv As DataGridView, ByVal setting As Boolean)
Dim dgvType As Type = dgv.[GetType]()
Dim pi As PropertyInfo = dgvType.GetProperty("DoubleBuffered", BindingFlags.Instance Or BindingFlags.NonPublic)
pi.SetValue(dgv, setting, Nothing)
End Sub
End Module


3- i call that module in Load Event:

Load Event

DoubleBuffer.DoubleBuffered(DataGridView1, True)


but it give me BLACK Cells

so, what is the problem i faced here?

Is this from a customised DataGridView control? That is, is the control you use a custom control that inherits from DataGridView? The only time I have seen things like this is when the control is customised and the _paint and/or _draw events are incorrectly implemented or something is missing from them

DataGridView

_paint

_draw

i only customized the rows align and the cells colors with no events, just from properties.
