ASP.NET Basics (Part 7): Command and Control - Test Drive (Page 4 of 7 ) Just as you can access data from text fields in an ASP.NET script, you can also evaluate the state of radio buttons and list boxes. To demonstrate, let's create a more complex form.
<html>
<head>
<basefont face=arial>
</head>
<body>
<h2> Survey</h2>
<form action="result.aspx" method="POST">
<p>
Do you plan to buy a car?
<input type="radio" value="Y" name="buycar">Yes
<input type="radio" value="N" name="buycar">No
<p>
What is your budget for the car, if you were to buy one? <select name="budget">
<option value="5" selected>> $1,000,000</option>
<option value="4">> $500,000 and < $1,000,000 </option>
<option value="3">> $250,000 and < $500,000</option>
<option value="2">> $100,000 and < $250,000</option>
<option value="1"> < $100,000</option>
</select>
<p>
<input type="submit" value="Submit Feedback">
</form>
</body>
</html>
And here's "result.aspx".
<script language="c#" runat="server">
void Page_Load()
{
// result.aspx
// define the variables and assign values
string budget_string = Request.Form["budget"];
string buycar = Request.Form["buycar"];
// convert string to number
int budget = Convert.ToInt32(budget_string);
// process and display
// "Y" to buying a car
if (buycar == "Y")
{
if(budget > 3)
{
output.Text = "So you're looking for a Ferrari or a Porsche, hmmm?";
}
else
{
output.Text = "We have the latest models from Ford and GM available for a test drive";
}
}
else
{
output.Text = "Hey, why not? Everybody has one these days...";
}
}
</script>
<html>
<head>
<basefont face="Arial">
</head>
<body>
<center><asp:label id="output" runat="server" /></center> </body> </html>
As you can see, evaluating radio buttons and list boxes is almost exactly the same as evaluating regular text fields. Next: The Taste Test >>
