I have changed my number to be a proper percentage, with the format mask "###,###,##0.00%"
I understand this means always show 2 decimal places and 1 integer number.
However percentages of 90.10% are being shown as 90.1%

The problem with the percentage happens because the percentage sign is a special formatting symbol, as explained here. To escape it, you can prefix it with a double backslash. With this change applied, your format string works as expected and 90.10 is shown as "90.10%" which, if I understand correctly, is the needed result: http://dojo.telerik.com/@tsveti/edoHo
