Server-side numeric filters

Hello there,
is there anyway to implemente a server-side numeric filter?

I have a grid that is linked to a datasource. It lists customers, and has a column that states the customers distance from the company. I would like to filter the grid by distance customers (e.g. >150) or close customers (<30), et… and also order the grid by distance…

Is there anyway to do this using server-side filters?

You can use server side events of the connector to attach any custom handler.
( from beforeFilter event you can access text from the client side input box and convert it to the necessary sql query )

Unfortunately there is no ready to use solution.
