Question

I\'m curious as to the best route (more looking towards simplicity, not speed or efficiency) to sort a DropDownList in C#/ASP.NET - I\'ve looked at a few recommendations b

If you are adding options to the dropdown one by one without a dataset and you want to sort it later after adding items, here's a solution:

DataTable dtOptions = new DataTable();
DataColumn[] dcColumns = { new DataColumn("Text", Type.GetType("System.String")), 
                           new DataColumn("Value", Type.GetType("System.String"))};
dtOptions.Columns.AddRange(dcColumns);
foreach (ListItem li in ddlOperation.Items)
{
   DataRow dr = dtOptions.NewRow();
   dr["Text"] = li.Text;
   dr["Value"] = li.Value;
   dtOptions.Rows.Add(dr);
}
DataView dv = dtOptions.DefaultView;
dv.Sort = "Text";
ddlOperation.Items.Clear();
ddlOperation.DataSource = dv;
ddlOperation.DataTextField = "Text";
ddlOperation.DataValueField = "Value";
ddlOperation.DataBind();

This would sort the dropdown items in alphabetical order.
