GridLookup - Incremental Filtering in Server Mode

Hosting the ASPxGridView internally (inside the dropdown window to display list items), the ASPxGridLookup editor has a capability to use a powerful data-processing functionality provided by the grid control. In particular, the ASPxGridLookup supports the grid's server mode functionality allowing the editor to efficiently work with large data sources by loading data in small portions, on demand. To work in server mode, the ASPxGridLookup editor should be bound to a data source of the XpoDataSource or LinqServerModeDataSource type.

As for entering tag names into the editor's edit box directly, this functionality is controlled by the TextFormatString and MultiTextSeparator properties. The TextFormatString property defines a column ("TagName") whose values should be entered and represented within the edit box. The MultiTextSeparator property specifies a value separator. List items (grid rows) that correspond to the entered tag names become selected automatically on submitting the entered value (for instance, pressing the ENTER key or invoking the dropdown window).
