Hello,

Could you please elaborate a bit more on your scenario? What is the type of the underling column data? The RadGrid filters the column based on the type of the data to which the column is bound. Additionally the grid’s column has FilterTemplate which you can use in order to implement an advanced filter for the column. On the following link you can find a live example which demonstrates this:

Please check it out and let me know if it helps you.
