Would you please send me a sample for CExtGridWnd in a dialog?

Could you please send me this example too?
Thanks

We sent the project you requested via e-mail.

Could I get a copy of this sample??

It seems pretty popular! ;)

Thanks,

Could you send me this sample as well?

Thanks in advance

We sent this project to you by e-mail.

Thanks for the sample.

I’m having a problem with selection on the grid. I created the control with the same style and exstyle as those in your sample, and created a subclass of CExtGridWnd. When I make a selection on the grid when it doesn’t have focus the selection is correctly shown, but once the grid has focus the selection is not changed in the display, even though it is saved cause when the grid lose focus the last selection is shown correctly again. Here’s the grid code:


class CMyGrid : public CExtGridWnd {
public:
    DECLARE_DYNCREATE(CMyGrid);

// Attributes
public:

// Implementation
public:
    void InitGrid();
};


IMPLEMENT_DYNCREATE(CMyGrid, CExtGridWnd);

void CMyGrid::InitGrid() {
    SiwModifyStyle(__EGBS_FIXED_SIZE_ROWS | __EGBS_SFB_FULL_ROWS |
            __EGBS_GRIDLINES | __EGBS_NO_HIDE_SELECTION, 0, false);

    OuterRowCountTopSet(2);

    ColumnAdd(5, false);
    for (int i = 0; i < 5; i++) {
        CExtGridCell* pCell = GridCellGetOuterAtTop(i, 0,
                RUNTIME_CLASS(CExtGridCellHeader));
        pCell->TextSet("X");
        pCell->ModifyStyle(__EGCS_TA_HORZ_CENTER);
        pCell->ExtentSet(80);
    }

    RowAdd(5, false);
    CExtGridCellVariant* pDataCell;
    for (int i = 0; i < RowCountGet(); i++) {
        for (int j = 1; j < ColumnCountGet(); j++) {
            pDataCell = STATIC_DOWNCAST(CExtGridCellVariant,
                    GridCellGet(j, i, 0, 0, RUNTIME_CLASS(CExtGridCellCurrency)));
            pDataCell->ModifyStyle(__EGCS_NO_INPLACE_CONTROL);
            pDataCell->_VariantAssign(0.0);
        }
    }

    OnSwUpdateScrollBars();
}


I call the InitGrid method in the OnInitDialog of the dialog.

You forgot to specify the scrolling strategy styles (__ESIS_STH_PIXEL|__ESIS_STV_ITEM styles) when invoking SiwModifyStyle(). Here is how to initialize the grid correctly:

void InitGrid()
{
    SiwModifyStyle(
        __ESIS_STH_PIXEL     // IMPORTANT: horizontal scrolling strategy
            |__ESIS_STV_ITEM // IMPORTANT: vertical scrolling strategy
            |__EGBS_FIXED_SIZE_ROWS
            |__EGBS_SFB_FULL_ROWS
            |__EGBS_GRIDLINES
            |__EGBS_NO_HIDE_SELECTION,
        0,
        false
        );
    OuterRowCountTopSet( 2 );
    ColumnAdd( 5, false );
    int  i, j;
    for( i = 0; i < 5; i++ )
    {
        CExtGridCell* pCell =
            GridCellGetOuterAtTop(
                i,
                0,
                RUNTIME_CLASS(CExtGridCellHeader)
                );
        pCell->TextSet("X");
        pCell->ModifyStyle(__EGCS_TA_HORZ_CENTER);
        pCell->ExtentSet(80);
    }
    RowAdd( 5, false );
    CExtGridCellVariant * pDataCell;
    for( i = 0; i < RowCountGet(); i++ )
    {
        for( j = 1; j < ColumnCountGet(); j++ )
        {
            pDataCell =
                STATIC_DOWNCAST(
                    CExtGridCellVariant,
                    GridCellGet(
                        j,
                        i,
                        0,
                        0,
                        RUNTIME_CLASS(CExtGridCellCurrency)
                        )
                    );
            pDataCell->ModifyStyle( __EGCS_NO_INPLACE_CONTROL );
            pDataCell->_VariantAssign( 0.0 );
        }
    }
    OnSwUpdateScrollBars();
}

Hi again,

I’m now having problems when selecting a row for which I need to scroll down the grid, if it’s my first selection it works fine, but when I select a visible row and then scroll down and select the last row it doesn’t highlight the selected row.

Thanks again for your help.

Would you send us the current version of the project so we can find out what’s wrong?

Sending you the current project is a bit difficult since it depends on a database which I cannot send you, anyway I’m gonna try to reproduce this behaviour in a new project and send it to you.
