TimeSpan string format exception

I've developed a web program in visual studio 2008 and converted it to 2010. In a Datagrid I have a data column with TimeSpan value. In 2008 I gave it string format 0:hh:mm and after the conversion I was getting a FormatException: Input string was not in a correct format. I corrected the string formattig to 0:hh\:mm as I found in Microsoft documentation for .NET 4.0. When I run the application from visual studio it works but when I copy it and run from the IIS it's still giving that error. What could be the problem?

In .NET version 3.5 and earlier, the TimeSpan struct wasn't IFormattable. Using a format string as in string.Format("Ipsum {0:HERE} ipsum", yourTimeSpan) would just ignore the format.

Since .NET 4.0, the TimeSpan is IFormattable. There's a new overload of ToString because of that, and it is called instead.
