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:

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


    if (!m_InitOn)

        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();

Dear Tarek,
Thanks a lot for your very interesting changes. But I have a problem with your code. When I use the Print command, the printed table will be very very small and also the table is reversed!!!! How can I solve it.

Thanks to you.
Best regards,
Bahman Tahayori

First On Dialog Set the Language Properties to Neutral (Sys. Default)

Second On your Project Settings -> Resources
Set Language To Arabic (Saudi Arabia)

this will work for arabic

Can you please post VC++ example using this control.
It is not clear how to use it in virtual mode and how to place this control into dialog or FormView.
Thank you.

welo_2000		1:55 23 Apr '03  
I made a very simple VC++ sample to use that, if u need it send to me.

all what u need is to write a piece of code similar to the following in ur dialog OnInitDialog():

m_cGrid.bCreateOnView = TRUE;
m_cGrid.Create(rect,this,1001);
m_cGrid.SetEditable(true);
m_cGrid.SetListMode(false);
m_cGrid.EnableDragAndDrop(TRUE);

// Construct the columns and rows
int nRows = 4;
int nCols = 3;
m_cGrid.SetRowCount(nRows+1);
m_cGrid.SetColumnCount(nCols+1);

m_cGrid.SetFixedRowCount(1);
m_cGrid.SetFixedColumnCount(1);

m_cGrid.SetColumnResize(FALSE);
m_cGrid.SetRowResize(FALSE);


int nArrIdx = 0;
for (int nCol = 1 ;nCol <= nCols ;nCol++)
{
GV_ITEM Item;
Item.mask = GVIF_TEXT|GVIF_FORMAT;
Item.row = 0;
Item.col = nCol;
Item.nFormat = DT_WORDBREAK;

CString str;
str.Format("Column %d",nCol);
Item.strText = str;


m_cGrid.SetItem(&Item);
}

for (int nRow = 1 ;nRow <= nRows ;nRow++)
{
GV_ITEM Item;
Item.mask = GVIF_TEXT|GVIF_FORMAT;
Item.row = nRow;
Item.col = 0;
Item.nFormat = DT_WORDBREAK;


CString str;
str.Format("Row %d",nRow);
Item.strText = str;
m_cGrid.SetItem(&Item);
}

can you send me a simple example I don't know how to integrate this code in my program .
also I don't know if the GridCtrl is a component that I must insert like I do for a CEdit or a button.
i found many samples but I don't suceed to understand how they introduce this control in CDialog

please help me !

can you explain me
where you declare the m_cGrid and how
and the number 1001 is it the id of the gridctrl

1. Consider adding a picture so the reader knows what you are talking about.
2. Some more explanations / text, rather than just code.
3. Add a credits section to the owner of the code (I understand from the introduction that you are adapting the code to work with Arabic, rather than did the code from scratch).

Regards,
Victor.
