I have noticed since I have upgraded to the latest version release of the Telerik ASP controls a strange behaviour with the DataStringFormat.  Previously, all my HTMLChart controls I was just specifying DataStringFormat="{0}" as I was already formatting the returned date from the SQL query in the MM/dd/yyyy format.  Once I upgraded my controls, whenever a date was being displayed on the chart for the axis label, it would instead show the actual characters {0}, not the date anymore.  I tried changing value to DataStringFormat="{0:MM/dd/yyyy}" and that did not work either, it would show like this {0:01/29/2013} on the axis.  Finally, I just took out the curly brackets and zero and used this DataStringFormat="MM/dd/yyyy" which worked.  This seems to only be a problem when using the {0} for the DataStringFormat on dates, but if it is just a number, like 10000 and I use DataStringFormat="{0:N0}" it shows correctly as 10,000.  Same thing with any other type of data aside of a date value.

Any idead why this is happening and why I cannot be consistant with the way the DataStringFormat is normally defined using the curly brackets and 0?

Thanks,
Ron
