dataFormatString with UpdatePanel

[cisco2103]

For some reason when I have a Update Panel around a grid and try using a dataFormatString it doesn't work. My code is correct because I have used it before without an updatePanel. DataFormatString="{0:MM-dd-yyyy}" Any thoughts

Here is my example: DateTime.UtcNow.ToString("MM-dd-yyy");
