Quick Tips


Persistent Radio Buttons
ASP pages are often used to both display a form, and carry out the action once the form is submitted. One of the most annoying tasks of HTML/ASP forms programing is keeping a user's chosen radio buttons selected when redrawing the form after it has been submitted. The following code is one way to create a one ASP page form that has persistent radio buttons:

<HTML>
<HEAD><TITLE>Pick a color</TITLE></HEAD>
<BODY BgColor=<%= Request.Form("Color")%>>
<%
RedChecked = ""
BlueChecked = ""
YellowChecked = ""


SELECT CASE Request.Form("Color")
CASE "Red"
RedChecked = "CHECKED"
CASE "Blue"
BlueChecked = "CHECKED"
CASE "Yellow"
YellowChecked = "CHECKED"
END SELECT
%>
Pick a color:<BR>
<FORM Method=Post>
Red: <INPUT Type=Radio Name=Color Value=Red <%= RedChecked%>>
Blue: <INPUT Type=Radio Name=Color Value=Blue <%= BlueChecked%>>
Yellow: <INPUT Type=Radio Name=Color Value=Yellow <%= YellowChecked%>>
<BR>
<INPUT Type=Submit>
</FORM>
</BODY>
</HTML>
