    text
    copied!<p>Since beginning to use <a href="http://en.wikipedia.org/wiki/Visual_Basic_.NET" rel="nofollow noreferrer">VB.NET</a> some years ago I have become slowly familiar with using the data binding features of .NET, however I often find my self bewildered by it's behavior and instead of discover the correct way it should work I find some dirty work around to suit my needs and continue on.</p> <p>Needless to say my problems continue to arise.</p> <p>I am using Custom Objects as the Data Sources for by controls and often entire forms. I find it frustrating to separate business logic and the graphical interface. (That could be a new question entirely.) So for a lot of objects I generate a form which has the <code>DataBindingSource</code> for the object. When I create each from using the New Constructor I explicitly pass to it the object to which it should be bound, and then set this passed object as the <code>DataSource</code> of the <code>BindingSource</code>. (That's a mouthful!)</p> <p>Now the Master object (say, bound to each form) often contains a List of objects which I like to have displayed in a <code>DataGridView</code>. I (sometimes) create and modify these child objects in their own form (again creating a databind the same way as the master form) but when I add them to the List in the master object the <code>DataGridView</code> won't update with the new items.</p> <p>So my question really has a few layers:</p> <ol> <li><p>How can I easily/efficiently/correctly update this <code>DataGridView</code> with the list of Detail objects when I add them to the list of the Master object.</p></li> <li><p>Is this approach to <code>DataBinding</code> good/viable.</p></li> <li><p>What's the best way to separate business logic from graphical interface.</p></li> </ol>
