Hello there,

I noticed something strange in the CExtGridWnd control. When I enable multiple row selection by adding the __EGBS_SFM_FULL_ROWS style I can expand the selection by holding shift and clicking a cell. When I enable multi-cell selected regions by adding the __EGBS_SFM_CELLS_HV style it is not possible to expand the selection this way.

Can I enable range expansion by shift+click in multi-cell mode?

Thanks in advance,

Bart.

I sent you an example project. Maybe you would like to answer?

If you wish I can send you an example project.

Initialization code:


grid.Create(this, CRect(10, 10, 500, 200));

grid.HoverEventsSet(true, true);
grid.SiwModifyStyle(__EGBS_RESIZING_CELLS_OUTER_H | __EGBS_RESIZING_CELLS_INNER_H, 0, false);
grid.BseModifyStyleEx(__EGBS_BSE_EX_DBLCLK_BEST_FIT_COLUMN_OUTER | __EGBS_BSE_EX_DBLCLK_BEST_FIT_COLUMN_MEASURE_INNER | __EGBS_BSE_EX_DBLCLK_BEST_FIT_COLUMN_MEASURE_OUTER, 0, false);
grid.BseModifyStyle(__EGWS_BSE_SORT_COLUMNS | __EGWS_BSE_SORT_COLUMNS_ALLOW_MULTIPLE | __EGWS_BSE_BUTTONS_IN_FOCUSED_CELL, 0, false);

// !! When using next line shift+click does not expand the selection, shift+arrow does.
grid.SiwModifyStyle(__ESIS_STH_PIXEL | __ESIS_STV_PIXEL | __EGBS_SFM_CELLS_HV | __EGBS_NO_HIDE_SELECTION | __EGBS_GRIDLINES | __EGBS_FIXED_SIZE_ROWS, 0, false);

// !! When using next line bpth shift+click and shift+arrow does expand the selection
//grid.SiwModifyStyle(__ESIS_STH_PIXEL | __ESIS_STV_PIXEL | __EGBS_SFM_FULL_ROWS | __EGBS_NO_HIDE_SELECTION | __EGBS_GRIDLINES | __EGBS_FIXED_SIZE_ROWS, 0, false);

grid.DefaultRowHeightSet(50, false);

grid.OuterRowCountTopSet(1);
grid.OuterColumnCountLeftSet(1);
grid.RowInsert(0, 5);
grid.ColumnInsert(0, 3);


Dear Bart,

Both shift+Arrow keys and shift+mouse click perform modification of the last rectangular selection region. This works in all __EGBS_SFM_*** selection models. Please show us the entire grid’s initialization source code.
