You can fine-tune a lookup editor by using the BaseEdit.StyleSettings property. This property allows you to alter the appearance and behavior of a lookup editor by adding extra features like searching and multiple item selection. To apply specific settings, assign the lookup’s BaseEdit.StyleSettings property to one of the objects listed in the table below.

LookUpEdit mode	Corresponding settings object	Description
LookUpEdit	LookUpEditStyleSettings	Editor’s dropdown displays a grid. This is a default setting.
SearchLookUpEdit	SearchLookUpEditStyleSettings	Editor’s dropdown displays a grid and a search box.
MultiSelectLookUpEdit	MultiSelectLookUpEditStyleSettings	Editor’s dropdown displays a grid that allows you to select multiple items.
TokenLookUpEdit	TokenLookUpEditStyleSettings	Editor’s dropdown displays a grid that allows you to select multiple items. Selected items are represented by tokens.
SearchTokenLookUpEdit	SearchTokenLookUpEditStyleSettings	Editor’s dropdown displays a grid and a search box. Allows multiple item selection. Selected items are represented by tokens.

Each of the settings objects has a number of properties that you can use to enable or disable the following grid features.

• Filtering (using the LookUpEditStyleSettings.AllowColumnFiltering property)
• Grouping (using the LookUpEditStyleSettings.AllowGrouping)
• Sorting (using the LookUpEditStyleSettings.AllowSorting)

The code example below shows a lookup editor in the SearchLookUp mode with grouping feature disabled.
