to filter u can use CrystalReportViewer.SelectionFormula;
For examaple To filter by a Customer_Id = 1
u can use
CrystalReportViewer.SelectionFormula ="Where Customer_Id = 1"

if u r using multiple selection formula u hav to use "and" or "or" to combine it

i think Arshad already give the solution

CrystalReportViewer.SelectionFormula() = "{Student.id_student}='" & Trim(txtIdStudent.text) & "' "

Student is the table Name & id_student is parameter
