public enum SearchMode


Name Description

The incremental search is enabled only when the dropdown window is open. If the window is closed, the user can modify the text in the edit box. However these changes are ignored.

When the dropdown is open the incremental search is performed against the column whose index is specified by the RepositoryItemLookUpEdit.AutoSearchColumnIndex property. The header of this column contains the search icon (binoculars). The user can click a specific column header to perform the search against this column.



Enables the automatic completion feature. In this mode, when the dropdown is closed, the text in the edit box is automatically completed if it matches a RepositoryItemLookUpEditBase.DisplayMember field value of one of dropdown rows.


When the dropdown is open, the automatic completion feature is disabled but the editor allows you to perform an incremental search in the same manner as when SearchMode.OnlyInPopup mode is active.


Enables the incremental filtering feature. When you type within the edit box, the editor automatically opens the dropdown window and displays only records whose RepositoryItemLookUpEditBase.DisplayMember field value starts with the characters typed. Other records are not displayed. If you enter a value that does not match any record, the dropdown window will not contain any rows.



The editor fires the AutoSuggest event that you should handle to assign an asynchronous Task. This task must check the user text currently entered into the editor’s text box, and return a collection of matching items. These items are shown in the editor’s drop-down panel.



The editor unlocks its text box and allows users to type in text. Data source records that match this text are shown in the drop-down panel.


Handle the editor AutoSearch event to fine-tune the search.
