the error

Compiler Error Message: CS0246: The type or namespace name 'AFFX' could not be found (are you missing a using directive or an assembly reference?)


im using HTML to build the selectbox


<select name='Afil1'>
    <option value="">- Please select affiliate -</option>
    <option value="5517">ABC Affiliate</option>
    <option value="5487">adsfdsfasdfffdddfd</option>
    <option value="5512">Affiliate ABC</option>
    <option value="5515">Affiliate test x</option>
  </select>

try this piece of code.

<html>

<head>

<script language="JavaScript">
function getValue() {
      alert(document.frmMain.mysel[document.frmMain.mysel.selectedIndex].value);
}


function getText() {
      alert(document.frmMain.mysel[document.frmMain.mysel.selectedIndex].innerHTML);
}
</script>

</head>

<body>
<form name="frmMain">
<select name="mysel">
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
</select>

<br><br>
<input type="button" value="Get Value" onclick="getValue()">
<br><br>
<input type="button" value="Get Text" onclick="getText()">
</form>
</body>

</html>

I presume you're ASP.NET?

If so, you need to use .NET controls for serverside, and not just HTML.

ie.

--.aspx file---
<asp:DropDownList id="dropDown" runat="server" Width="176px">
      <asp:ListItem Value="1">one</asp:ListItem>
      <asp:ListItem Value="2">two</asp:ListItem>
</asp:DropDownList>

--.aspx.cs file---
protected System.Web.UI.WebControls.DropDownList dropDown;


Then you can access it like a normal control :

Response.Write(dropDown.SelectedItem.Text);

and

Response.Write(dropDown.SelectedItem.Value);

If you have to use just plain HTML, then I guess setting the value the same as the text is the easiest way to go, if not the only way.

Not sure how much you know about ASP.NET, but remember its served to the user as plain HTML, the code above is purely serverside.
