Currently, ASPxTreeList does not provide built-in filtering options/visual elements. I suggest that you execute the following steps:
- Pre-filter ASPxTreeList on the server side before data binding based on your custom conditions;
- Bind the TreeList with filtered data to display the required portion of nodes.
We will update the S130999 - Support Filtering report once anything new regarding this feature is available.
You can add that report to your Favorites List to be notified of updates.
