Filter and smart rendring issue

Hello, we have dhtml grid pro license, we have implemented select filters(#select_filter) with smart rendring enabled dhtmlgrid, but filters not getting it’s option values when grid load initially, and throws an error(screen shot atached).

I also tried with event onCollectValues, and now it is loading default option values for filters but error is still there and filters not working.

Please help it is urgent.

Thanks in advance.

In case of using dynamic loading you need to implement the server-side filtration according to the following tutorial: … parameters
or using the connector’s filters.
