  • About this demo

This example demonstrates Automatic Datasource operations with the RadTreeList control. Here the treelist controls are bound to a SqlDataSource and an ObjectDataSource correspondingly.
In order to enable the execution of the automatic CRUD operations with RadTreeList, one needs to properly define the Insert/Update/Delete parameters of the datasource controls. Other than this, the functionality is automatically handled, without the need to write any custom code or set additional properties.
