For some reasons I need to join some cells along a column in a CExtGridWnd. I have used as starting point, your sample "JoinCells". In your sample, the joining is made along cells on the same row, so I have changed the code in order to perform my request. The join works, but I found some strange breaviours with it. First of all the cells selection do not work has expected, if I select the first cell joined in the column (from up to down), the selection works, then if I try to select the other cell the selection do not work.
Can you give me some suggestion and help? This is the code I used to do the join:
void CMyGrid::OnGbwAdjustRects( LONG nColNo, LONG nRowNo, INT nColType, INT nRowType, RECT & rcCellExtraA, RECT & rcCellA ) const { ASSERT_VALID( this ); CExtGridWnd::OnGbwAdjustRects( nColNo, nRowNo, nColType, nRowType, rcCellExtraA, rcCellA );
//if(nColType == 0 && nRowType == 0 && nRowNo == 1) // { // if(nColNo == 1) // { // CRect rcCellA_Next, rcCellExtraA_Next; // if(GridCellRectsGet( // nColNo + 1, // nRowNo, // nColType, // nRowType, // &rcCellA_Next, // &rcCellExtraA_Next)) // { // rcCellA.right = rcCellA_Next.right; // rcCellExtraA.right = rcCellExtraA_Next.right; // } // } // else if(nColNo == 2) // { // rcCellA.left = rcCellA.right; // rcCellExtraA.left = rcCellExtraA.right; // } // } if(nColType == 0 && nRowType == 0) { if(nRowNo == 1 && nColNo == 1) { CRect rcCellA_Next, rcCellExtraA_Next; if(GridCellRectsGet( nColNo, nRowNo + 1, nColType, nRowType, &rcCellA_Next, &rcCellExtraA_Next)) { rcCellA.bottom = rcCellA_Next.bottom; rcCellExtraA.bottom = rcCellExtraA_Next.bottom; } } else if(nRowNo == 2 && nColNo == 1) { rcCellA.top = rcCellA.bottom; rcCellExtraA.top = rcCellExtraA.bottom; } } }
Many thanks Francesco.
