FilterMode Enumeration

Provides members that specify the TreeList filtering mode.

Namespace:DevExpress.XtraTreeList
Assembly:DevExpress.XtraTreeList.v18.1.dll

Expanded Public Members

Show: Inherited
  Name Description
Public field Default The same as: See also: Version Compatibility: Default Property Values.
Public field Extended Nodes that match the applied filter are displayed regardless of whether their parent nodes fit the filter.

Unlike the Smart mode, if a node matches the applied filter, all its parent nodes are also displayed even if they do not fit the filter.
Public field Smart Nodes that match the applied filter are displayed regardless of whether their parent nodes fit the filter.

Unlike the Extended mode, parent nodes that do not match the filer are not displayed.
Public field Standard Nodes that match the applied filter are only displayed if their parent nodes also fit the filter.

If a node fits the filter but any of its parent nodes does not, the node is not displayed.

Top

Expanded Remarks

Using the TreeListOptionsFilter.FilterMode property that uses the FilterMode enumerator values as parameters, you can set three options for filtering nodes. The Standard mode displays child nodes that match a specific criterion only when all the node's parents match this criterion as well. If this behavior limits your tasks, use the Smart or Extended mode instead.

For DevExpess installation of versions 17.1 and newer, Tree List filtering is already enabled and managed by the TreeListOptionsCustomization.AllowFilter property. For older versions, enable the TreeListOptionsBehavior.EnableFiltering property.
