I can figureout which cell is checked but I have to know the whole rows checked status when one cell generate the checked event. is there any way to figure out which row is checked in the whole grid rows. please let me know ˆˆ

My source is like this

bool CXGridTextCell::OnClick(
  CExtGridWnd & wndGrid,
  const CExtGridHitTestInfo & htInfo,
  UINT nChar, // VK_LBUTTON, VK_RBUTTON or VK_MBUTTON only
  UINT nRepCnt, // 0 - button up, 1 - signle click, 2 - double click, 3 - post single click & begin editing
  UINT nFlags // mouse event flags
 )
{
 if( nChar == VK_LBUTTON && nRepCnt == 1 )
 { // if single left button click
  if( (nFlags&(MK_SHIFT|MK_CONTROL)) == 0 )
  { // if neither Shift nor Ctrl keys was pressed
   if( (htInfo.m_dwAreaFlags&__EGBWA_CELL_CHECKBOX) == 0 )
   {
...   } // if( (htInfo.m_dwAreaFlags&__EGBWA_CELL_CHECKBOX) == 0 )
   else

   {
    CString sProductNo;
    CExtGridCell* cGridCell;

   int nRowCount;
    nRowCount = ((CXGridCtrl*)&wndGrid)->m_nRowCount;
    for (int i = 0;i < nRowCount; i++)
    {
     cGridCell = (CXGridTextCell*)wndGrid.GridCellGet(0, i);
     
     DWORD dwCellStyle = cGridCell->GetStyle();
     if( ((dwCellStyle&__EGCS_CHECKED) != 0))
      cGridCell->TextGet(sProductNo);
    }

   }//Ckeckbox Clicked

...

The CExtGridCell::OnClick() virtual method has the constant CExtGridHitTestInfo & htInfo parameter that completely describes the location of the cell being clicked and even which part of the cell is hovered by the mouse pointer (check box, button, text area and etc). You need to use htInfo.m_nColNo and htInfo.m_nRowNo as cell coordinates.
