Body
In my application I have a main windows and into it, in a frame I load a page. This page do a long time task when the user press a button. My problem is that when long task is being doing and the user presses the close button of the main window, the application seems to not finish because I am debugging it in VS2008 and I can see the stop button highlighted. If I want to finish I have to press stop button, the application doesn't stop the debugging automatically on application exit. I thought .NET stops automatically backgroundworkers on application exits but I am not sure after seeing this behaviour. I have tried to force and cancel background worker in unloaded event page with something like this: <pre><code> private void Page_Unloaded(object sender, RoutedEventArgs e) { // Is the Background Worker do some work? if (My_BgWorker != null && My_BgWorker.IsBusy) { //If it supports cancellation, Cancel It if (My_BgWorker.WorkerSupportsCancellation) { // Tell the Background Worker to stop working. My_BgWorker.CancelAsync(); } } } </code></pre> but with no success. After doing CancelAsync(), a few minutes after, I can see the backgroundworker finishes and raise RunWorkerCompleted and I can see the task is completed checking e.Cancelled argument in the event but after this event is exectued the application continues without exiting and I have no idea what is doing.... I set WorkerSupportsCancellation to true to support cancel at the begining. I would apreciate all answers. Thanks.

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.
