Displaying null value to gridview from database

Hello everyone, I once again would like your assistance. I have this query below:

SELECT DISTINCT sg.StudentID,
(sm.Fname + ' ' + sm.Lname + ' - ' + sm.NickName) AS StudentName,
ISNULL(sg.Q1, 0) as Q1,
ISNULL(sg.Q2, 0) as Q2
FROM dbo.tblStudentGradesTwoTerms sg INNER JOIN
dbo.tblEnrollmentHeader eh ON sg.EnrollmentID = eh.EnrollmentID INNER JOIN
dbo.tblStudentTeacherMaster sm ON sg.StudentID = sm.StudentTeacherID AND eh.StudentID = sm.StudentTeacherID
WHERE sg.SchoolCode = @SchoolCode AND
sg.SchoolYear = @SchoolYear AND
sg.GradeLvl = @GradeLvl AND
sg.SubjectID = @SubjectCode

and this is what it displays in my gridview:

How not to display the 0? I want to display only blank if students doesn't have grades yet.

Thanks for any assistance.
