Thanks for paste your code. You can do one thing. Create a method for only bind select query option. And call it on page load and then your problem will solve.

Answer 4

Hi,

    Can you show me your binding code ?

 

Answer 5

After your page load write one ajax call which will take value from current drop down & passes to action method, now from action method returns data into Json, JsonResult, List format & bind to your grid / div.

Refer my article which has a button click event & on button click event I had ajax call & taking data from action result & binding it. Just for your reference

2)  https://www.c-sharpcorner.com/article/dynamically-bind-the-dropdownlist-on-change-event-in-asp-net-mvc-5/

 Let me know if any concern.
