User defined form creation

Question

I have a requirement to create dynamic fields for form. Searched online and here and found this design guideline while it miss some of my requirements. I don't need exact code but general guideline.

User will have DropDownList with Properties he can add. Each Property divided into two parts. First part is for User to use for SearchCombination ( combination of Properties) and other part is for Customer to use.

ie. User chooses Age in DropDownList, this should produce AgeFrom/AgeTo DropdownLists on SearchCombination page and Day/Month/Year DropDownLists on Customer page.

How can i tackle this problem? Again i need only guideline and no real code unless you want to so please no suggestions "What have you tried", this is design question.

The only solution i see it to follow solution above while SearchCombination and Costumer control groups will be UserControls at the same table

Thanks

Here is a tiny simple version, hope this guides you in the right direction

  if(DropDownList.SelectedValue == "age")
    {
       DropDownList listFromAge = new DropDownList();
       listFromAge.DataSource = myAgeDataSource;
       Controls.Add(listFromAge);

       DropDownList listToAge = new DropDownList();
       listToAge.DataSource = myAgeDataSource;
       Controls.Add(listToAge);

    }
