Hi mate,
What you could do is download the source code and modify that part and it will do the way you want it.
Go the the source project:
Telerik.Web.Mvc>UI>DropDownList>DropDownListHtmlBuilder.cs
Change this line from : input.Attribute("value", selectedItem.Value.HasValue() ? selectedItem.Value : selectedItem.Text);
to :input.Attribute("value", selectedItem.Value.HasValue() ? selectedItem.Value : "");
This is located at the end of the file.
Rebuild it and use the DLL.
