Using RadComboBox with AutoComplete as a custom editor in RadGrid

 

HOW-TO Use RadComboBox with enabled AutoComplete as a custom editor in RadGrid

DESCRIPTION
In some situations the developer may need to load combobox items "on demand" in a dropdown grid column editor. This is useful when presenting large number of items in that dropdown list.

SOLUTION
You can use one of the following approaches:

• The built-in GridDropDownColumn which now supports RadComboBox. The combo is populated using the WebService.
• GridTemplateColumn with RadComboBox added to the EditItemTemplate section. The combo is populated in the ItemsRequested event handler.

Both methods are used in the attached combobox-in-grid-autocomplete.zip project.
