Node Selection
Node Focusing
You can enable the focused row feature to indicate the last clicked tree node. This is useful when using the ASPxTreeList for navigation purposes. It can also be used with data-browser trees when you must display node details in a separate control. For instance, it can be used when displaying forum messages to highlight the node whose details are currently displayed.
End-users move node focus by clicking nodes they desire. ASPxTreeList allows you to perform the following actions both on the client and server side:
-
respond to changing node focus;
-
identify a node currently being focused;
-
move node focus.

Simple Node Selection
Multi-node selection is also a built-in feature of ASPxTreeList. By toggling a single option, you can enable selection check boxes within rows and display a Select All check box within the header panel. End-users can check or uncheck these check boxes to select or unselect the corresponding nodes.

Recursive Node Selection
DevExpress tree list control supports recursive node selection. When recursive selection is enabled:
-
A parent node is automatically selected if all its child nodes are selected. Deselecting a child node automatically unselects its parent node(s);
-
Selecting a parent node automatically selects all its children.
