ASP Lesson 11: Combo Boxes and Searching
Viewing a list of records.
As we saw in Lesson 11, we can create a table that contains hyperlinks to a record we want to view. We can also accomplish this by creating a Combo Box that we fill dynamically. Rather than passing data in the querystring, as in Lesson 10, we will now pass data as a form element.
Combo Box Search Form (frmCombo.asp)
<!--#include virtual="/includes/adovbs.inc"-->
<!--#include virtual="/includes/subConn.inc"-->
<html>
<head>
<title>Select Student</title>
</head>
<body>
<form action="frmStudent.asp"
method="post">
<table border="1">
<tr>
<td>Student Name:</td>
<td>
<%
sql = "SELECT * " & _
"FROM gb_student " & _
"ORDER BY lname"
openCN
rs.Open sql, cn
response.write "<select name=sid size=1>" & vbCrLf
do while not rs.EOF
response.write "<option value=" & _
rs("sid") &">" & _
rs("lname") & "," & _
rs("fname") & "</option>" & vbCrLf
rs.MoveNext
loop
rs.Close
closeCN
response.write "</select>" & vbCrLf
%>
</td>
</tr>
<tr>
<td colspan="2">
<input type="submit"
value="Submit">
</td>
</tr>
</table>
</form>
</body>
</html>
Sample output:
Student Record Form (frmStudent.asp):
<!--#include virtual="/includes/subConn.inc"-->
<!--#include virtual="/includes/adovbs.inc"-->
<%
sid=request.form("sid")
sql = "SELECT * FROM Students WHERE sid='" & sid & "'"
openCN
rs.Open sql, cn
%>
<html>
<head>
<title>Student Information</title>
</head>
<body>
<form>
<table bgcolor="#C0C0C0">
<tr>
<td align="left">strong>Student

Apply what you have learned.
Using the search form created in this lesson, and the grade form you have created in previous lessons, modify the grade form to display the students full name, and all their exam scores, based on the student name passed from the search form.
