    <p>I've got a method called Import that imports the data of an xml file into the database. It looks like this:</p> <pre><code>private void SavingXMLFile() { //Save the file: if (rootElement != null) { try { using (FileStream fsHosp = new FileStream("Data/ConfigOrgHospital.xml", FileMode.Truncate, FileAccess.Write)) { using (XmlWriter x = XmlWriter.Create(fsHosp)) { SerializeHospitalData(x, rootElement); } } } catch (Exception e) { MessageBox.Show(e.Message); } try { Import("Hospitals"); } catch (Exception e) { MessageBox.Show(e.Message); } } </code></pre> <p>Then it goes to the import method:</p> <pre><code>public void Import(string sourceFile) { IProgressReporter progressReporter = new ProgressReporter(); BackgroundThreading.RunInBackground&lt;int&gt;((object input) =&gt; { foreach (IConfigRunner runner in Runners.OrderBy(r =&gt; r.Priority)) { runner.DoImport(progressReporter, sourceFile); } return 0; }, (answer, error, w) =&gt; { if (error != null) { //ShowError(error); } else { //AddProgress("Export ready"); } //DoReady(); }, (error) =&gt; { //ShowError(error); }); } </code></pre> <p>Then it does a DoImport:</p> <pre><code>public interface IConfigRunner { int Priority { get; } void DoExport(IProgressReporter progress); void DoImport(IProgressReporter progress, string filename); } [Export] public void DoImport(IProgressReporter progress, string filename = null) { if (filename.Equals("Hospitals")) { if (File.Exists(HOSPITALFILE)) { progress.AddProgress("Importing " + HOSPITALFILE); using (OrgEntities orgEntityModel = ModelFactory.GetOrgEntities()) { Tools.ValidateXml(HOSPITALFILE, "Xsd\\hospital.xsd"); XmlSerializer inSerializer = new XmlSerializer(typeof(HospitalRoot)); TextReader reader = new StreamReader(HOSPITALFILE); HospitalRoot root = (HospitalRoot)inSerializer.Deserialize(reader); reader.Close(); try { OrgHospitalXml.Insert(orgEntityModel, root.Hospitals); } catch (ImportException e) { progress.AddProgress(e.Message + ": " + e.Item); throw e; } } } } </code></pre> <p>Is there any way that I can show the progression of this in a progressbar? Or how to find all the UI Threads? Thx in advance</p> <p>BackgroundWorker:</p> <pre><code>public static class BackgroundThreading { public static BackgroundWorker RunInBackground&lt;T&gt;(object param, Func&lt;object, T&gt; call, Action&lt;T, Exception, BackgroundWorker&gt; callBack, Action&lt;Exception&gt; errorHandler = null) where T : new() { BackgroundWorker worker = new BackgroundWorker(); DoWorkEventHandler workHandler = null; RunWorkerCompletedEventHandler completeHandler = null; workHandler = delegate(object s, DoWorkEventArgs args) { args.Result = call(args.Argument); args.Cancel = worker.CancellationPending; }; completeHandler = delegate(object s, RunWorkerCompletedEventArgs args) { if (!args.Cancelled) { if (args.Error != null) { if (!(args.Error is FaultException)) { T result = new T(); callBack(result, args.Error, (BackgroundWorker)s); } else { if (errorHandler == null) { string message; if (args.Error.InnerException != null) { message = args.Error.InnerException.Message; } else { message = args.Error.Message; } Logger.LogError("SVC", Logger.SVC_ERROR_001, new object[1] { message }); throw args.Error; } else { errorHandler(args.Error); } } } else { callBack((T)args.Result, null, (BackgroundWorker)s); } ((BackgroundWorker)s).DoWork -= workHandler; ((BackgroundWorker)s).RunWorkerCompleted -= completeHandler; } }; worker.DoWork += workHandler; worker.RunWorkerCompleted += completeHandler; worker.WorkerSupportsCancellation = true; worker.RunWorkerAsync(param); return worker; } public static BackgroundWorker RunInBackground&lt;T&gt;(Func&lt;object, T&gt; call, Action&lt;T, Exception, BackgroundWorker&gt; callBack, Action&lt;Exception&gt; errorHandler = null) where T : new() { return RunInBackground&lt;T&gt;(null, call, callBack, errorHandler); } </code></pre>

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.

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