 # DevExtreme DropDownBox - Search Within an Embedded DataGrid
 
-This example implements a search that filters data in a [DataGrid](https://js.devexpress.com/Documentation/Guide/UI_Components/DataGrid/Getting_Started_with_DataGrid/) placed into a [DropDownBox](https://js.devexpress.com/Documentation/Guide/UI_Components/DropDownBox/Getting_Started_with_DropDownBox/) component.

-## Implementation Details
-
-The example handles the following [DropDownBox](https://js.devexpress.com/Documentation/ApiReference/UI_Components/dxDropDownBox/) events to synchronize search behavior between the input field and the embedded DataGrid:
-
-1. The [onInput](https://js.devexpress.com/jQuery/Documentation/ApiReference/UI_Components/dxDropDownBox/Configuration/#onInput) event fires when the user types in the DropDownBox. The event handler opens the dropdown (if it is not already open) and passes the entered text to the Grid's `dataSource.searchValue()` method.
-
-2. The [onOpened](https://js.devexpress.com/jQuery/Documentation/ApiReference/UI_Components/dxDropDownBox/Configuration/#onOpened) event fires when the dropdown opens. The event handler registers a one-time listener on the DataGrid to move focus to the component once the grid is ready for keyboard navigation.
-
-3. The [onClosed](https://js.devexpress.com/jQuery/Documentation/ApiReference/UI_Components/dxDropDownBox/Configuration/#onClosed) event fires when the dropdown closes. The event handler resets the search state: if the entered text does not match a valid selection, the handler either selects the first available row or clears the DropDownBox value.
+This repository contains code referenced in the following DevExtreme help topic: [DropDownBox - How To Search by Field Values (DataGrid)](https://js.devexpress.com/Documentation/Guide/UI_Components/DropDownBox/Search_in_Embedded_Components/#Search_by_Field_Values_DataGrid).
