<h2>Sorting</h2>
-
+<p>
+TDataGrid supports sorting its items according to specific columns. To enable sorting, set <tt>AllowSorting</tt> to true. This will turn column headers into clickable buttons if their <tt>SortExpression</tt> property is not empty. When users click on the header buttons, an <tt>OnSortCommand</tt> event will be raised. Developers can write handlers to respond to the sort command and sort the data according to <tt>SortExpression</tt> which is specified in the corresponding column.
+</p>
+<p>
+The following example turns Example 2 into a sortable datagrid. Users can click on any link button displayed in the header of a column and the data will be sorted in ascending order along that column.
