    <p>I've been trying to follow this MSDN <a href="http://msdn.microsoft.com/en-us/library/cc221403%28v=vs.95%29.aspx" rel="nofollow noreferrer">example</a>, and using the code below. However, <code>e.Error</code> is ALWAYS null in RunWorkerCompleted even when an error does occur in SomeMethod();</p> <pre><code>private void WorkerDoWork(object sender, DoWorkEventArgs e) { getMethod = SomeMethod(); } private void Worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Error != null) { var result = ModernDialog.ShowMessage("Error occurred.... " + e.Result, "ErrorTitle", MessageBoxButton.OK); } else if (e.Cancelled) { } Else { } } </code></pre> <p>Can anyone see what I'm doing wrong?</p> <p>I can get around it by doing the following but I don't really understand why the example in MSDN is not working for me?</p> <pre><code>private void WorkerDoWork(object sender, DoWorkEventArgs e) { try { getMethod = SomeMethod(); } catch(Exception ex) { e.Result = ex; } } private void Worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Result is Exception) { var result = ModernDialog.ShowMessage("Error occurred.... " + e.Result, "ErrorTitle", MessageBoxButton.OK); } //etc } </code></pre> <p>Also, using the second method I can't access the .Message from e.Result. For example, in WorkerDoWork I can use <code>ex.Message</code></p> <p>Edit: I've setup the worker to create it's own error and I still get e.Error == null. The variable displayed is a bit faint as CTRL+PrtSc makes it fade <img src="https://i.stack.imgur.com/m85GI.png" alt="enter image description here"></p>

    1. COIn WinForms, I cannot duplicate the issue. Are you sure you aren't catching the error somewhere?

    2. CODefinitely not catching the error, SomeMethod(); contains no try,catch statements. It's in a WPF app if that makes a difference?

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).
