format dropdownlist control have two columns

Tien Quang

I want to fill data into select control like:

abc || 1
bcde || 2
ghiftt || 3

And my code

string str = "";
if (arr != null)
{

foreach (MProductInfo info in arr)

{
string select = "";
if (info.ID == id_select)
select = "selected";
string sName = string.Format("{0}{1}", info.Name.PadRight(70, '\u00A0'), info.Code);
str += "";
}

}
return str;

Ressult:

abc || 1
bcde || 2
ghife || 3

So how to fix it?

use dropdown control of asp.net
and bind

if static data then
DataTable dt =New Datalist();
dt.Columns.Add("FullName", typeof(string), "FirstName + ' ' + LastName");
//add more column in datalist
dropdownlist1.DataSource = dt;
dropdownlist1.DataTextField = "FullName";
dropdownlist1.DataValueField = "ID";
dropdownlist1.DataBind();

if you are binding from database

DataTable dt =New Datalist();

// write code to get data in datalist
//query -- select firstvalue+'-'+secondvalue from table
dropdownlist1.DataSource = dt;
dropdownlist1.DataTextField = "FullName";
dropdownlist1.DataValueField = "ID";
dropdownlist1.DataBind();
