Property Value

Type	Default	Description
ColumnSortMode	Default	The sort mode.

Available values:

Name	Description
Default	The actual sort mode is determined by a control. See the property description for more details.
Value	Sorts the column’s data by the column’s edit values (these are synchronized with the bound data source’s values).
DisplayText	Sorts the column’s data by the column’s display text (the strings displayed within the column’s cells).
Custom	Applies sort options specified in the CustomColumnSort event handler. In data grids, this mode also applies group options from the CustomColumnGroup event handler.

Remarks

The SortMode property specifies the algorithm used to sort TreeViewControl data (by display text, edit value, or a custom sorting algorithm).

The Default option is DisplayText if the TreeViewControl uses in-place editors inherited from the LookUpEditSettingsBase class (ComboBoxEditSettings, LookUpEditSettings). The Default option is Value in other cases.

Follow the steps below to apply custom logic to sort data:

1. Set the SortOrder property to Ascending or Descending.
2. Set the SortMode property to Custom.
3. Handle the CustomNodeSort event.
