    <p>As others have pointed out, _geoLoc isn't defined. Try something like this</p> <pre><code>internal GeoLoc GetMyGeoLocation() { try { //create a request to geoiptool.com var request = WebRequest.Create(new Uri("http://geoiptool.com/data.php")) as HttpWebRequest; if (request != null) { //set the request user agent request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727)"; //get the response using (var webResponse = (request.GetResponse() as HttpWebResponse)) if (webResponse != null) using (var reader = new StreamReader(webResponse.GetResponseStream())) { //get the XML document var doc = new XmlDocument(); doc.Load(reader); //now we parse the XML document var nodes = doc.GetElementsByTagName("marker"); Guard.AssertCondition(nodes.Count &gt; 0,"nodes",new object()); //make sure we have nodes before looping //if (nodes.Count &gt; 0) //{ //grab the first response var marker = nodes[0] as XmlElement; Guard.AssertNotNull(marker, "marker"); var _geoLoc = new GeoLoc(); //get the data and return it _geoLoc.City = marker.GetAttribute("city"); _geoLoc.Country = marker.GetAttribute("country"); _geoLoc.Code = marker.GetAttribute("code"); _geoLoc.Host = marker.GetAttribute("host"); _geoLoc.Ip = marker.GetAttribute("ip"); _geoLoc.Latitude = marker.GetAttribute("lat"); _geoLoc.Lognitude = marker.GetAttribute("lng"); _geoLoc.State = GetMyState(_geoLoc.Latitude, _geoLoc.Lognitude); return _geoLoc; //} } } // this code would only be reached if something went wrong // no "marker" node perhaps? return new GeoLoc(); } catch (Exception ex) { throw; } } </code></pre>

    2. COOnce you have the result from the method call, you can set the text of your TextBlock to use properties on the GeoLoc object.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
