Remarks

The default behavior is to keep the expanded state of nodes when a user filters data. Set the ExpandNodesOnFiltering property to true to automatically expand collapsed nodes when they match the current filter. See the Filtering topic to learn more.

The ExpandNodesOnFiltering property is not in effect if the TreeList.EnableDynamicLoading option is enabled.

Use the TreeListOptionsCustomization.AllowFilter property to enable data filtering in Tree List.
