Use the SortOnClick property to disable sorting items when the user clicks on the column's header. Use the SortBarVisible property to show the control's sort bar. Use the SingleSort property to allow sorting by single or multiple columns. Use the AllowSort property to avoid sorting a column when user clicks the column. Use the DefaultSortOrder property to specify the column's default sort order, when the user first clicks the column's header. Use the SortChildren method to sort a column, at runtime. Use the DisplaySortIcon property to hide the sort icon if the column is sorted. Use the HeaderVisible property to show or hide the control's header. Use the BackColorHeader property to specify the header's background color. Use the AllowSizing property to disable resizing a column when user clicks the right margin of the column.

There are two methods to get the items sorted like follows: 

• Using the SortOrder property of the Column object::

  View1.Columns(ColIndex).SortOrder = SortAscending

  The SortOrder property adds the sorting icon to the column's header, if the DisplaySortIcon property is True. 

• Using the SortChildren method of the Items collection. The SortChildren sorts the items. The SortChildren method sorts the child items of the given parent item in the control. SortChildren will not recourse through the tree, only the immediate children of the item will be sorted. The following sample sorts descending the list of root items on the "Column 1"( if your control displays a list, all items are considered being root items ).

  View1.Items.SortChildren 0, "Column 1", False
