You can create on custom column concating more than one value using any separator like |: etc...

Solution 1

C#

public class Data
    {
        public int Id { get; set; }
        public string Col1 { get; set; }
        public string Col2 { get; set; }
        public string Col3 { get; set; }

    }

var data = List<data>();

var dropdownData = data.Select(x=>new {Id = x.Id, Value = x.Col1+ "|" + x.Col2 + "|" + x.Col3}).ToList();

DropdownList.DataSource = dropdownData;
 DropdownList.DataTextField = "Value";
 DropdownList.DataValueField = "Id";
DropdownList.DataBind();
</data>

You can create generic list as displayed above and bind it with dropdown.
You will get 3 values binded with Dropdown concatened with "|".

You can merge two column in your sql query like if you want to show the first_name and last_name to your dropdown you can use following query...

select first_name + ' ' + last_name as full_name from tbl_name

now you can bind full_nameto your dropdown.Hope this will help in your problem...
