How can we make an http request using the filters? We simply followed previous instructions.
Do you mean to implement remote sorting? What is the problem exactly? Could you please provide your solution here and point us what is not working for you?
Remote filtering. We just need to pass the query params for rest api to handle and return the values.
If you're using AjaxStore in you Combo, you can set the params dynamically in beforeRequest. If you have static params you can define them in params config
