Enable the AllowSelectRowByClick property to allow users to select and deselect rows by mouse clicks, tap gestures, and keyboard shortcuts. To select a range of rows, users should hold down the Shift key and click the first and last rows in the range. To add/remove a row to/from selection, users should hold down the Ctrl key and click the row.

<DxGrid Data="@DataSource"
        RowClick="OnRowClick"
        AllowSelectRowByClick="true"
        ...>
    @*...*@
</DxGrid>

You can use the GridRowClickEventArgs.ShiftKey and GridRowClickEventArgs.CtrlKey event arguments to define whether the Shift or Ctrl key was pressed when a user clicked rows.
