    <p>I have a form which creates a BackgroundWorker. The worker then does some work, and does a ReportProgress to send messages back to the UI while it's busy. I then log those messages to the UI. The ReportProgress is done by a single method in the thread, which I called 'Notify'.</p> <p>However, within the thread, I call a static class to do file access type work. That static class needs to also report progress... so I need to call the Notify method of the thread class that called the static class - but, I have no access to the methods within the calling class. </p> <p>So, UI creates thread... and thread uses a class, but I need to call the Notify method in the class, from the static class. How can I do this?</p> <p>This is my attempt to far. The idea is to try use a delegate... but, I am stuck at actually using the delegate. :)</p> <p>In my thread class, I have a method:</p> <pre><code>public void Notify(string message, Constants.ErrorLevel errorLevel) { var su = new StatusUpdate {StatusMessage = message, ErrorLevel = 0}; _bw.ReportProgress(0, su); } </code></pre> <p>This is working. It reports well to the calling UI.</p> <p>I now created a delegate in this class:</p> <pre><code>public delegate bool NotificationsDelegate(object MessageHolder); </code></pre> <p>I have changed my static class for handing file management, to non-static, and am wanting to pass that delegate to the file manager class when I create it:</p> <pre><code>public class FileManager { private readonly NotificationsDelegate _notifications; public FileManager(NotificationsDelegate notifications) { _notifications = notifications; } private void SendMessageBack(string p, ConsoleColor consoleColor) { var su = new StatusUpdate {ErrorLevel = 0, StatusMessage = p}; _notifications(su); } </code></pre> <p>So, I create it, and pass the Notification delegate... and then in my 'SendMessageBack' method, hope to call the delegate (called _notifications).</p> <p>But that's where I am stuck. The delegate isn't assigned to the notify method yet. I'm new to events, so guessing my way around. But, can someone help me get this right?</p>

    1. COPass the BackgroundWorker to the method in the static class so it can call ReportProgress?

    2. COI was thinking of this, but then on each time I use the static method, I have to add the bw object to each call?

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.
