Formatting a TemplateColumn of a datagrid

Question

Hello, I am using a datagrid in which one of the columns is a TemplateColumn that shows a date. I want to format this date to the appropriate date according to the client's timezone. For that, i have to call a javascript function which uses "getTimezoneOffset" function to calculate the client's date and time. This is the part of the code where i need to format the data: Is it possible to call a javascript function when building the table? Thanks, Dana
