Hello unodgs

Sorry. I have found the problem in my program but I do not know how to fix it.

The problem comes from a field with "SetDisplay" that gets the exception when pasting from Notepad and corrupts the Date field beside it as described in the posts.

For example this works right:
myGridCtrl.AddColumn(ISMARRIED, t_("Is married?")).Edit(isMarried).Default(-1);

and this wrong:
myGridCtrl.AddColumn(ISMARRIED, t_("Is married?")).SetDisplay(Single<DispPM>()).Edit(isMarried).Default(-1);

isMarried is declared this way:
DropGrid isMarried;

And initialized this way:
isMarried.Add(1, t_("Yes")).Add(-1, t_("No"));

So I want to store an integer from a DropGrid with strings.

Going to DisPM, as I want to see "Yes" or "No" in the cells, this is the original version that works properly with rows copied directly from GridCtrl but gets an exception if copied from Notepad:

struct DispPM : GridDisplay
{
virtual void Paint(Draw &w, int x, int y, int cx, int cy, const Value &val, dword style, Color &fg, Color &bg, Font &fnt, bool found, int fs, int fe)
{
String text;
if(!val.IsNull())
text = int(val) > 0 ? "Yes" : "No";
else
text = "";
GridDisplay::Paint(w, x, y, cx, cy, Value(text), style, fg, bg, fnt, found, fs, fe);
}
};

This other version lets paste from Notepad but does not show "Yes" or "No" but empty cells

struct DispPM : GridDisplay
{
virtual void Paint(Draw &w, int x, int y, int cx, int cy, const Value &val, dword style, Color &fg, Color &bg, Font &fnt, bool found, int fs, int fe)
{
w.DrawRect(x, y, cx, cy, bg);
if(!val.IsNull())
w.DrawText(x, y, int(val) > 0 ? "Yes" : "No", fnt, fg);
GridDisplay::Paint(w, x, y, cx, cy, Value(""), style, fg, bg, fnt, found, fs, fe);
}
};

Do you have any idea?

Best regards
Iñaki
