Body
If Lines is a <code>List<T></code>, then the simplest way is to just write: <pre><code>cart.Lines.RemoveAll(x => x.Quantity == 0); </code></pre> If Lines is an <code>IEnumerable<T></code>, though, you could select the negative (as Vlad suggested) - you could also change to a list using <code>ToList()</code> and then do <code>RemoveAll()</code> but that would be overkill. <pre><code>cart.Lines = cart.Lines.Where(x => x.Quantity != 0); </code></pre> UPDATE: Since you said Lines is an <code>IList<T></code>, then you will want to select the negative and convert to a list like: <pre><code>cart.Lines = cart.Lines.Where(x => x.Quantity != 0).ToList(); </code></pre> Or you can conver to a <code>List<T></code> using <code>ToList()</code> then call <code>RemoveAll()</code> and then save back: <pre><code>var temp = cart.Lines.ToList(); temp.RemoveAll(x => x.Quantity != 0); cart.Lines = temp; </code></pre> Incidentally, as an FYI I timed both building a remove list and then using <code>Remove()</code> vs selecting the negative using <code>Where()</code> and calling <code>ToList()</code> and the Where/ToList combo was much faster which makes sense because both allocate memory, but the Where/ToList does a lot less memory shuffling. Here's the timing for removing all the even numbers out of a list of 100,000 ints: <ul> <li>Removing all evens building a remove list and calling Remove() on each took: 3921 ms</li> <li>Removing all evens using Where() on negative and then ToList() took: 2 ms</li> <li>Removing all evens using ToList() on original then RemoveAll() took: 1 ms</li> </ul>

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.
