Sort items from xml source before populate dropdown
How do I sort items from my xml source before populating the dropdown?
XmlNode xnode = ts.Ranges();
ddlRanges.Items.Add(new ListItem("--Select One --", "0"));
foreach (XmlNode n in xnode)
{
ddlRanges.Items.Add(new ListItem(n.FirstChild.InnerText, n.FirstChild.NextSibling.InnerText));
}

You could use LINQ to xml, here is an example from

<?xml version="1.0" encoding="utf-8" ?>
<root>
<node>3</node>
<node>4</node>
<node>1</node>
<node>2</node>
<node>5</node>
</root>
XDocument xml = XDocument.Load("XMLFile.xml");
xml.Root.ReplaceNodes(xml.Root.Elements("node").OrderBy(el => el.Value));
xml.Save("XMLFile.xml");

I am looking to sort the data in this xml source : http://www.toyota.co.za/api/Toyota.asmx/Dealers
Where i would have a dropdown with the values like this for example :
Eastern Cape - Dealership Name1
Eastern Cape - Dealership Name2
Eastern Cape - Dealership Name3
Eastern Cape - Dealership Name3
Kwa Zulu Natal - Dealership Name1
etc.

My solution is attached, thanks for your help guys :)
XmlNode dealersregions = ts.Dealers();
// Create the output table.
DataTable yourDataTable = new DataTable();
yourDataTable.Columns.Add("dealerCode");
yourDataTable.Columns.Add("dealerName");
yourDataTable.Columns.Add("region");
foreach (XmlNode n in dealersregions)
{
DataRow myNewRow;
myNewRow = yourDataTable.NewRow();
myNewRow["dealerCode"] = n.FirstChild.NextSibling.InnerText;
myNewRow["dealerName"] = n.FirstChild.NextSibling.NextSibling.NextSibling.InnerText + " - " + n.FirstChild.InnerText;
yourDataTable.Rows.Add(myNewRow);
}
DataView dv = new DataView(yourDataTable);
dv.Sort = "dealerName";
ddlDealer.DataValueField = "dealerCode";
ddlDealer.DataTextField = "dealerName";
ddlDealer.DataSource = dv;
ddlDealer.DataBind();
but you can use XPathExpression.AddSort to help you sort

or else you can first loop around the xml and add all the elements to a sorteddictionary object and then do the databinding of the dropdown with the sorted dictionary
