Hello, Ramachandran, 

Thank you for writing.  

The GridViewDataColumn provides a unified way of converting incompatible value types to a type supported by the column instance. The standard .NET Framework TypeConverter subclasses are used to convert values between data types. Additional information for converting the cell values is available here: http://docs.telerik.com/devtools/winforms/gridview/columns/converting-data-types

I hope this information helps. Should you have further questions I would be glad to help.

Regards,
