How to bind a wegrid dynamically with help of dropdown MVC

Question

I have one query table that holds three columns namely id, name, query. I want to bind id as a value name as a text in drop down and when I change the drop down list that query column is executed in web grid dynamically. I don't know how to do this.

Thank you

qry_id	qry_name	qry_query
1	customer	select cus_name, cus_street, cus_address, cus_place, cus_mobile from customer_master
2	product	select sup_code, sup_name from supplier_master
