Painting issues while horizontal scrolling when changing extended window styles

Hi All,

I have a instance of DataGridView in my form and overridden the CreateParams method and changed the extended window styles as below,

protected override CreateParams CreateParams
{
    get
    {
        CreateParams Param = base.CreateParams;
        Param.ExStyle |= 0x02000000;
        return Param;
    }
}

When i make any cell in half of the grid and scroll using Horizontal scrollbar in the grid, it shows some painting or redrawing issues while scrolling. Scrolling works normal if i dont change the extended window styles.

Could someone please update us, what is the cause of this repainting while scrolling the grid?

Thanks and Regards,
