Question

I want to fill data into select control like:

bcde || 2
ghiftt || 3

And my code

string str = "<option value='0'>" + strApp + "</option>";
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 += "<option " + select + " value='" + info.ID + "'>" + sName + "</option>";
}

}
return str;

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();
