Incremental Search

Grid Views support incremental searches, i.e. they locate records by typing the initial characters of the desired cell's display value. This enables end-users to locate the desired records quickly when Grid Views display a large amount of data. This topic describes how to enable and use an incremental searching feature. To learn how to locate rows via code, please refer to the Locating Rows in Code topic.

Expanded Incremental Search

To enable incremental searching, set the View's GridOptionsBehavior.AllowIncrementalSearch property to true. A column's OptionsColumn.AllowIncrementalSearch option can be used to disable the incremental search for this column.

To search for a record by a field value, an end-user should first focus the column in which they want to search and then type the first character(s) of the desired value. The grid will focus the row that contains the typed text in the focused column.

In some cases there may be several rows containing cells matching the search criteria. To continue searching backwards and forwards using the current criteria, end-users can press the CTRL+UP and CTRL+DOWN key combinations respectively.

It is possible to start and stop an incremental search manually. For this purpose, use the GridView.StartIncrementalSearch and GridView.StopIncrementalSearch methods. To get the text being searched during an incremental search use the ColumnView.GetIncrementalText method.

The following animation demonstrates an incremental search sample (note: the search text is typed in with the help of the On-Screen Keyboard available in Windows XP).
