I am creating a school management system. And I want user to type a particular name in a textbox to display the student's exams records into the Crystal Report.
But my code isn't working.

What I have tried:

Try

Sql = "select * from Student where Fullname = '" & txtname.Text &'""
Connect()
cmd = New OleDbCommand (Sql,con)
dr = cmd. ExecuteReader ()

While dr.Read
CrystalReportViewer1.Rows.Add
End while

Catch ex As Exception
End Try

Your code is vulnerable to SQL Injection[^].

NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.

Solution 1

Your code just adds rows to the CrystalReportViewer1, it does not add any data to the added row so you get a blank row for each record from the database.
