Solution 1

you could try the following algorithm:
*when clicked 'request'
1. Clear all items from dropdown list.
2. add the 4 items that you want to display.
*when clicked 'request dc'
1. Clear all items from dropdown list.
2. add the 2 items that you want to display.

Solution 2

Before binding dropdownlist with its query just clear the items like
1) Dropdownlist.Items.Clear()
2) then your query
3) Dropdownlist.DataBind()
