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

i have tried DoubleBuffered like that:

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:

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 – JayV Jun 29 '18 at 09:59
  • i only customized the rows align and the cells colors with no events, just from properties. – Point_Systems Jun 29 '18 at 10:10
