Whenever the post back event happens in a grid then it will be loading the full grid. Can you try having the drop down as separate control out of grid and on selected element change event in the drop down list load the grid data accordingly. In UI you can make HTML & CSS style to show the dropdown is available in the same div where the grid is available. Hope this logic will help for you. If not please post your code here. Mark as answer if helpful.
