c# - ASP.NET Form value validation scenario -

I have the following html in my ASP.NET form. It represents a dropdown menu so that users can choose their own budget. . When a user selects a value on the list, a jquery code project bags a copy of the selected value in the hidden area, so it can be submitted through the form.

  & lt; P & gt; & Lt; Label & gt; Project Budget * & lt; / Label & gt; & Lt; / P & gt; & Lt; A href = "#" class = "SelectionDropdownMenu" & gt; Select the budget value & lt; / A & gt; & Lt; Input id = "projectbizit" class = "inputdumpdown value" runat = "server" type = "hidden" /> & Lt; Ul class = "DropdownMenu" & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; $ 5000 or less & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; 5 000 $ - 10 000 dollars & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; $ 10,000 - $ 25,000 & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; 25 000 $ - 50 000 $ & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; $ 50 000 - $ 100 000 & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; $ 100 000 or more & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; NA & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt;  

This solution worked well for me in the past, but I did not need to do any verification on the field and using an unordered list, our web designers on the dropdown list more Provides flexibility. / P>

However I want to add ASP.NET validation to make budget selection compulsory.

What are my options besides using a DropDownList and using a RequiredFieldValidator?
