dropdownlist

Question

I'm using this code to sort values in dropdownlist :
DropDownList1.DataSource = DropDownList1.Items.Cast<ListItem>()
.OrderBy(o => o.Value).ToList();
ddlApoeni.DataBind();
the problem is that result is descending order, but i want ascending ?

Hi When you are call OrderBy its give the ascending order. Here my complete sample code public static IEnumerable OrderBy (this IEnumerable list string sortExpression) { sortExpression += ; string[] parts = sortExpression.Split(' '); bool descending = false; string property = ; if (parts.Length > 0 && parts[0] != ) { property = parts[0]; if (parts.Length > 1) { descending = parts[1].ToLower().Contains(esc); } PropertyInfo prop = typeof(T).GetProperty(property); if (prop == null) { throw new Exception(No property ' + property + ' in +  + typeof(T).Name + '); } if (descending) return list.OrderByDescending(x => prop.GetValue(x null)); else return list.OrderBy(x => prop.GetValue(x null)); } return list; } Thank you
