    <p>Is there a way to sort a <code>List&lt;T&gt;</code> using a string like <code>"Name desc"</code> (same as <code>DataTable.DefaultView.Sort</code>) rather then Linq?</p> <p>I'm trying to replace <code>DataTables</code> with <code>Lists</code> and I need it to do this to be compatible with old code.</p> <p><strong>SOLUTION</strong></p> <p>using V4Vendetta's code I was able to create this extension method, tests seem to show it working.</p> <pre><code>public static void SortByString&lt;T&gt;(this List&lt;T&gt; list, string sortString) { if (sortString == null) return; List&lt;string&gt; SortGroups = sortString.Split(',').ToList(); for (int i = SortGroups.Count - 1; i &gt;= 0; i--)// sort from the last group first { string tempColumn = SortGroups[i].Trim().Split(' ')[0]; bool isAsc = SortGroups[i].Trim().Split(' ').Length &gt; 1 ? SortGroups[i].Trim().Split(' ')[1].ToLower() == "asc" ? true : false : true; PropertyInfo propInfo = typeof(T).GetProperty(tempColumn); if (propInfo == null) // if null check to make sure its not just a casing issue. { foreach (PropertyInfo pi in typeof(T).GetProperties()) { if(pi.Name.ToLower() == tempColumn.ToLower()) { tempColumn = pi.Name; propInfo = typeof(T).GetProperty(tempColumn); break; } } } if (propInfo != null) { Comparison&lt;T&gt; compare = delegate(T a, T b) { object valueA = isAsc ? propInfo.GetValue(a, null) : propInfo.GetValue(b, null); object valueB = isAsc ? propInfo.GetValue(b, null) : propInfo.GetValue(a, null); return valueA is IComparable ? ((IComparable)valueA).CompareTo(valueB) : 0; }; list.Sort(compare); }else{ throw new IndexOutOfRangeException("Property: '" + tempColumn + "', does not exist in '" + typeof(T).ToString() + "'"); } } } </code></pre>

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.
