Dear Support,

If you insert into a number cell, for example, 5 and the the - sign (that is 5- ) the cell somehow swaps the 5 & - into -5.

I would like to prevent the user from inserting the - sign after a number, only before a number.

I tried to set m_nNegativeOrder to 1, I added also virtual UINT OnQueryNegativeOrder() const { return 1; } , but still the - after the number is there.

Please help.

You should override the CExtGridCellNumberBase::OnFormatCellText() virtual method. Your method should invoke the parent class method and then remove unneeded characters on the right using the strCopy.TrimRight( _T(" \t-") ); code.
