Our most recent update introduced multi cell selection support to the DevExpress Web Forms and MVC Grid View, Vertical Grid, and Tree List controls. This new feature allows users to select a cell range by hovering the mouse over the control - then copying the range (and pasting it into grid cells, external controls, or Microsoft Excel).
To enable multi cell selection in your DevExpress-powered WebForms or MVC app, set edit mode to Batch and the EnableMultipleCellSelection property to true.
<dx:ASPxGridView ID="Grid" runat="server" DataSourceID="DemoDataSource" KeyFieldName="ProductID">
<SettingsEditing Mode="Batch">
<BatchEditSettings EnableMultipleCellSelection="true" />
</SettingsEditing>
</dx:ASPxGridView>

Cell Selection API
The following API allows you to integrate cell selection within your WebForms and/or MVC app:
- The SelectCell method selects a cell.
- The UnselectCell method deselects a cell.
- The GetSelectedCells method obtains information about the selected cells.
- The CellSelectionChanging event fires when a user selects or deselects a cell.
