How to filter the drop down list by using other drop down list in asp.ner MVC

everyone, I encounter a problem when I开发者_如何学C try to filter the drop down list.

The situation is I wish to filter the Agent dropdown list by using the Company dropdown list in same view/form. Since I need to display the Agents that only belong to the selected Company. But I have no idea to do that.

Any solution, please?
