This is a previous version of Chris Maunders MFC Grid control
(version 1.03) with a minor bug fix and several improvements.
First a bug fix:
OnEditCell() Event handler to prevent it:
if ((nRow < m_nFixedRows)||(nCol < m_nFixedCols)) return;
And the improvements:
- I had the need to delete all rows but without the fixed rows and all the column
attributes (see section 3), so I add function DeleteAllRows(). - I added an UINT array:
m_arColType
This array holds the Edit Type for each column. This Edit Type can take one of these
values: - GVET_NOEDIT (0x0000) cells in this column are not editable.
- GVET_EDITBOX(0x0001) cells in this column are editable in the old way (i.e. inplace Editbox is opened for the cell).
- GVET_LISTBOX (0x0002) cells in this column are editable in the way that an inplace Listbox is opened for the user to select value for this cell.
There are more styles (GVET_COMBOBOX, GVET_CHECKBOX) that are not implemented for now.
(maybe someone would take the challenge to implement those styles before I do
J).
attribute as well:
int InsertColumn(LPCTSTR strHeading, UINT nFormat = DT_CENTER|DT_VCENTER|DT_SINGLELINE, int nColumn = -1, int nType = GVET_NOEDIT);
and I added the function:
BOOL SetColumnType(int nCol, int nType);
virtual void FillListItems(int nCol, LPARAM cltList);
To use the Listbox cells attribute, you have to inherit your class from the
CGridCtrl and override the function : FillListItems. This function is called before
any inplace listbox is opened in order to fill its items by AddString. You can set
the user-defined data for each listbox item. This data is attached to the Grid items
user-defined data. (This is useful for lookup lists in the grid).
