I am looking into the viability of the treelist control and have a question.
I have a sample treelist on the screen where the data source is a simple list of data objects.
I have a button the screen that just adds an extra item of data to the server side data list, but I need to know how to get the tree to refresh automatically. If I expand any item in the tree, my new item appears, so I know the new data is being added.

Hi,
Thank you for contacting us.
When you add/remove items manually from RadTreeList datasource you may need to call the Rebind() method manually if you are not using the control events. Additionally, you may need to set the DataSource property to null before calling the Rebind() method if you need to explicitly call the NeedDataSource event.
Give these suggestions a try and you should not have problems.
