ASPxGridView - How to implement cascading combo boxes in Batch Edit mode by using WebMethods

This example shows how to implement cascading combo boxes in EditingSettings "Batch" mode by using WebMethods. The example is based on ASPxGridView - How to implement cascading comboboxes in Batch Edit mode and How to populate a cascading ASPxComboBox by using WebMethods examples. The main idea is to remove EditTemplate from ASPxGridView and replace the ASPxComboBox Callback by WebMethods to refresh the child's combo box item collection. This will improve the server's response time and reduce the server's load.
