This demo is based on the sample provided in example E1362. It uses custom callbacks to implement cascading comboboxes in a detail GridView. Two comboboxes edit two database fields. The value list in a depended control is filtered based on the value selected in master control.

I cannot get this example to work properly. I have followed it exactly using my own data. In the display grid (not in edit mode) the GridViewDataComboBoxColumn for Category2ID is displaying the ID value instead of the Textfield value even though the TextField and ValueField is set properly and both fields are returned by the data source. Also, when editing, the Category1ID Combobox never allows selection to occur and Category2ID is not updated.
