Classic ASP Dropdown Lists and Default Values

**ianbhenderson73** · May 23rd, 2012, 04:34 AM

Hello

I am in the process of trying to create some Classic ASP web pages. The first page will allow the user to select data using a number of different criteria, some of them entered as text fields and others as selections in combo boxes (drop-down lists).

Once the user has made his/her selection, s/he is taken to a second page which displays the results of the search.

To be clear, the code for the first and second pages is sound: everything works exactly as I want it to. However, I'm looking at putting a link onto the second page that enables the user to return to the initial search screen and refine the search without having to re-enter all the criteria. I can get the first page displaying once more, and have started the job of re-populating all of the fields according to the values that were originally passed from page 1 to page 2.

My problem is this: how do I assign an existing value to a combo box? When I repopulate the text fields, it's simply done using the value attribute for that field, and deciding whether the page is a new load or a reload from the second page. However when I try to do this using a combo box I get told that the value attribute is not valid for a select element.

Can someone tell me how I get around this issue?

Thanks

Here are 2 very simple asp pages that may give you some ideas.

Page 1

Code:

<html>
<head><title>Main Page</title>
</head>
<body>
	<&#37;
		Dim color		
		color = Request.QueryString("color")
	%>
	
	<form id="frm" action="page2.asp" method="post">
		<select id="color" name="color">
			<option value="">-- Select a color --</option>
			<option value="Red" <% If color = "Red" Then Response.Write(" selected")%>>Red</option>
			<option value="Green" <% If color = "Green" Then Response.Write(" selected")%>>Green</option>
			<option value="Blue" <% If color = "Blue" Then Response.Write(" selected")%>>Blue</option>
		</select>
		<input type="submit" id="submit" value="Submit" />	
	</form>
</body>
</html>

Page 2

Code:

<html>
<head><title>Page 2</title>
</head>
<body>
	<%
		Dim color		
		color = Request.Form("color")
	%>
	
	Your selected color is <%=color%> <br />
	<a href="page1.asp?color=<%=color%>">Return to the main page</a>
</body>
</html>
