Update your question with button click event handler. I suspect you are not rebinding the grid after postback.

Show the code of ShowApplicant. Did you check that it returns data when ApplicantName is selected?

Not that having ApplicantName and ApplicantID in user interface, seen by the user is bad design. User should see friendly "normal" language something like:
Search by: <- label
Identifier <- combobox item 1
Applicant Name <- combobox item 2

I'm guessing you are assuming that if it is a postback one of your buttons has been pressed. While this does kind of work, when you have multiple buttons there is no way of knowing which button caused the postback. So you need to implement click events for the buttons and put the relevant code in the relevant click event.
