Here is my ASP code

XML

<select id="Manufacturer" name="Manufacturer" <asp:Literal ID='litManfDis' runat='server' />
                  Manufacturer:  <option>SELECT MANUFACTURER</option>
                    <asp:Literal ID="litManf" runat="server" />
                </select>

Here is how I fill my select options.

Dim strManaufacturer As String = Utilities.IsNull(Request.Form("Manufacturer"))

SQL

ds = dbnet.Manufacturers("select distinct I001001 from TESTDATA.VININDEX")
     For Each dr As DataRow In ds.Tables(0).Rows
       litManf.Text &= String.Format("<option{0}>{1}</option>", IIf(dr("I001001").ToString().Trim().Equals(strManaufacturer, StringComparison.InvariantCultureIgnoreCase), " selected=selected", String.Empty), System.Web.HttpUtility.HtmlEncode(dr("I001001").ToString().Trim()))
     Next

But I do not know how to get the selected value into a string.
Can anyone help me with this?

Which selected value? I don't understand.

selected value of this "Manufacturer". In ASP.NET if we use some ddl.selectedvalue to get selected value. But with this literals I cannot figure out how to get selected value

I don't quite understand why you are doing the way you are doing it now. Can't you use ASP.NET control. what's the reason for you are doing it this way.

I cannot use ASP controls. Because this project was developed entirely with literals and they want it to be continued like this only.

I would suggest to use javascript/jquery to update a hidden field in your HTML with the selected value on selected event then use it in your server side.
In javascript you can use like this

JavaScript

for (var i = 0; i  < document.getElementById("Manufacturer").options.length; i++) {
       if(select.options[i].selected ) {
