The column to add to the collection.

True to specify that the column should also be grouped by, as well as sorted.

Example
Following code shows how to programmatically sort rows. SortIndicator property returns the current state of sorting on the column. If the column is sorted, then it returns either Ascending or Descending depending on how the column is sorted. It returns None if the column is not sorted. It can also return Disabled if the property was set to that value previously. You can also set the property to change it's sort status. For example, you can set the property to Ascending and Descending to sort row by the column. You can set it to None to clear sorting. You can set it to Disabled to prevent the user from sorting by that column.
