    <p>I'm trying to return the last 7 days of data from an xml web service but with no luck. Could someone please explain me to how I would accomplish this? The XML is as follows:</p> <pre><code>&lt;node&gt; &lt;api&gt; &lt;usagelist&gt; &lt;usage day="2011-01-01"&gt; &lt;traffic name="total" unit="bytes"&gt;23579797&lt;/traffic&gt; &lt;/usage&gt; &lt;usage day="2011-01-02"&gt; &lt;traffic name="total" unit="bytes"&gt;23579797&lt;/traffic&gt; &lt;/usage&gt; &lt;usage day="2011-01-03"&gt; &lt;traffic name="total" unit="bytes"&gt;23579797&lt;/traffic&gt; &lt;/usage&gt; &lt;usage day="2011-01-04"&gt; &lt;traffic name="total" unit="bytes"&gt;23579797&lt;/traffic&gt; &lt;/usage&gt; &lt;/usagelist&gt; &lt;/api&gt; &lt;/node&gt; </code></pre> <p><strong>EDIT</strong></p> <p>The data I want to retrieve will be used to populate a line graph. Specificly I require the day attribute value and the traffic element value for the past 7 days. At the moment, I have the code below in place, howevewr it's only showing the first day 7 times and traffic for the first day 7 times.</p> <pre><code>XDocument xDocument = XDocument.Parse(e.Result); var values = from query in xDocument.Descendants("usagelist") select new History { day = query.Element("usage").Attribute("day").Value, traffic = query.Element("usage").Element("traffic").Value }; foreach (History history in values) { ObservableCollection&lt;LineGraphItem&gt; Data = new ObservableCollection&lt;LineGraphItem&gt;() { new LineGraphItem() { yyyymmdd = history.day, value = double.Parse(history.traffic) }, new LineGraphItem() { yyyymmdd = history.day, value = double.Parse(history.traffic) }, new LineGraphItem() { yyyymmdd = history.day, value = double.Parse(history.traffic) }, new LineGraphItem() { yyyymmdd = history.day, value = double.Parse(history.traffic) }, new LineGraphItem() { yyyymmdd = history.day, value = double.Parse(history.traffic) }, new LineGraphItem() { yyyymmdd = history.day, value = double.Parse(history.traffic) }, new LineGraphItem() { yyyymmdd = history.day, value = double.Parse(history.traffic) }, }; lineGraph1.DataSource = Data; } </code></pre>

    1. COPlease specify what web service you're using and what call you're making to this. Without this information it's impossible to provide any answer as there's clearly not enough context.

    2. COHi Gergely, I have updated my original question and hope it makes more sense now :) As for specifying what web service i'm using, it's for my ISP and requires authentication to view.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
