The ASPxTreeList control allows you to filter data. When a filter condition is applied, the control displays only data nodes that meet the criteria. Data nodes can be filtered against a single or multiple data columns.
If recursive selection is enabled, when you select a parent node, it automatically selects its visible and hidden child nodes.
You can allow end users to filter data nodes by column values or by display text. Use the FilterMode property to specify a column's filter mode. Note that users cannot filter by display text in database server mode.

Use the Search Panel to find a node by its content. The filter criterion does not need to match the cell value(s) completely.
In virtual mode, the ASPxTreeList's filter mechanism is not applied to child nodes whose parent nodes are collapsed.
