Displaying multiple values in datagridview by filter searching

Question

I was making a vb program that searches a student info by searching a course.. For example Ajax's course is "BSCS" and DP's course is "BSIT" , then i'm going to select BSCS, so Ajax's must only appear not DP. The result appear's in DataGridView

    myConnection.Open()
    Dim str As String
    str = "SELECT * FROM students WHERE (Course = '" & TextBox1.Text & "')"
    Dim cmd As OleDbCommand = New OleDbCommand(str, myConnection)
    dr = cmd.ExecuteReader
    While dr.Read()
        FirstNameTextBox = dr("FirstName")
        MiddleNameTextBox = dr("MiddleName")
        LastNameTextBox = dr("LastName")
        AddressTextBox = dr("Address")
        CellphoneNumberTextBox = dr("CellphoneNumber")
        CourseTextBox = dr("Course")
    End While
    myConnection.Close()

Based on your Code you should add new DataGridView to your form and also adding columns with header name that you choose and replace the code with mine

        myConnection.Open()
        Dim str As String
        str = "SELECT * FROM students WHERE (Course = '" & TextBox1.Text & "')"
        Dim cmd As OleDbCommand = New OleDbCommand(str, myConnection)
        dr = cmd.ExecuteReader
        While dr.Read()
           DataGridView1.Rows.Add({dr("FirstName"),  dr("MiddleName"), dr("LastName"), dr("Address"), dr("CellphoneNumber"), dr("Course")})
        End While
        myConnection.Close()
