SearchLookUpEdit Class

The editor that provides lookup functionality using a dropdown feature-rich data grid (GridControl), and contains the built-in Find Panel, allowing end-users to quickly filter and locate dropdown rows.

Namespace:DevExpress.XtraEditors
Assembly:DevExpress.XtraGrid.v17.2.dll

Expanded Syntax

Expanded Remarks

A lookup editor is an editor with an embedded dropdown window which displays lookup records (the records from which an end-user can select). When a lookup record is selected, the editor's value (the BaseEdit.EditValue bindable property) and display text are modified accordingly.

The SearchLookUpEdit displays lookup records in the dropdown using the feature-rich data grid - GridControl. Unlike its predecessor, the SearchLookUpEdit supports a built-in Find Panel, which allows an end-user to quickly locate rows by the text they contain.

By default, lookup records are presented in the standard column-row format using a GridView View.

You can specify a different View to present data, with the RepositoryItemGridLookUpEditBase.PopupViewType property (e.g., in a card format). The settings of the chosen View can be accessed and customized via the RepositoryItemGridLookUpEditBase.PopupView property.

To learn how to set up lookup editors in different binding modes, see the following topics:

You may want to filter the popup data source of one (secondary) lookup editor based on a value of another (primary) lookup editor. This scenario is covered in the following topic:

The SearchLookUpEdit and GridLookUpEdit controls have many features in common. These controls are identically created and customized (except for the additional features that are only typical to the SearchLookUpEdit control). Please refer to the GridLookUpEdit topic for an example.

Expanded Additional Customization

The following list shows some of the members that help you perform the additional customization of the SearchLookUpEdit control.

Search Settings

There are two search modes - automatic and manual. In automatic search mode, a search starts following a small delay after an end-user has stopped typing text. In manual search mode, a search is started manually by pressing ENTER or clicking the Find button.

Automatic search mode is in effect in the following cases:

Manual search mode is in effect in the following cases:

The RepositoryItemGridLookUpEditBase.PopupFilterMode property specifies how dropdown rows are filtered - using the Contains or StartsWith filter. By default, this property is set to PopupFilterMode.Default, which is equivalent to the Contains filter.

The PopupFilterMode property also affects columns against which data is searched. See the PopupFilterMode topic to learn more.

To embed a SearchLookUpEdit in a cell within a container control (XtraGrid, XtraTreeList, etc), use the RepositoryItemSearchLookUpEdit component. See the Repositories and Repository Items topic, for more information.

Note

The SearchLookUpEdit clears the active filter after closing the dropdown window.

Note

Instant Feedback Mode is supported by the SearchLookUpEdit when the control is used as a standalone control and when the control is used as an in-place editor within a Grid Control.

Note

The GridLookUpEdit and SearchLookUpEdit controls do not have a connection to their underlying data sources while their dropdown windows are closed. So in this instance it is not possible to access the underlying data or a grid's calculated data using methods provided by the embedded Grid Control and its View. You can use these methods only when the controls' dropdown windows are open.

While the dropdown windows are closed, you can access the underlying data using methods provided by the underlying data source.
