Introduction

I tried to use many grids of different types in Arabic mode but I failed, until I found GridCtrl with source. And then I worked to adapt it to work with Arabic mode in different types of Views or Dialogs.

Working with views:

void CSomeClassToWorkAsView::OnInitialUpdate() 
{
    CView::OnInitialUpdate();

    // TODO: Add your specialized code here and/or call the base class

    if (!m_InitOn)

        CRect rect;
        GetClientRect(rect);
        m_pGridCtrl->Create(rect, this, 1001);

        m_InitOn = true;
    }
    if (m_InitOn)
    {
        ReGetData();
    }
}

Working with cells' merge:

            for (col = 0; col < m_Grid.GetColumnCount(); col++)
            { 
                m_Grid.SetItemBkColour(iRowCur, col, RGB(165, 27, 30));
                m_Grid.SetItemFgColour(iRowCur, col, RGB(255, 255, 0));
            }
            m_Grid.SetSelectedRange(iRowCur, ID_QUTNAME, iRowCur, ID_SELX);
            m_Grid.MergeSelectedCells();
