Remarks
The ASPxTreeView supports automatic synchronization of node selection with the path of the currently browsed page. You can choose synchronization mode by specifying the SyncSelectionMode property value.
The table below lists the available property values with their descriptions:
| Value | Description |
|---|---|
| CurrentPath | The node whose TreeViewNode.NavigateUrl property value points to the URL of the currently browsed page, is displayed selected. In this case, the query string appended to the URL is ignored. |
| CurrentPathAndQuery | The node is automatically selected if its TreeViewNode.NavigateUrl property value matches the URL and query string of the page which is currently being browsed. |
| None | Automatic selection synchronization is disabled. |
Note
Automatic selection synchronization is enabled if the ASPxTreeView.AllowSelectNode property is set to true.
Note
The SyncSelectionMode property affects the ASPxTreeView control behavior in virtual mode.
In virtual mode, the ASPxTreeView.VirtualModeCreateChildren event fires when expanding a node for the first time.
- When the SyncSelectionMode is set to None, the ASPxTreeView.VirtualModeCreateChildren event only fires for the node being expanded.
- Otherwise, the ASPxTreeView.VirtualModeCreateChildren event fires for the node being expanded, and for all previously expanded nodes.
