This example shows the sorting modes supported by Telerik Grid for ASP.NET MVC. The user can sort either by a single column only (GridSortMode.SingleColumn which is the default) or sort simultaneously by more than one column (GridSortMode.MultipleColumn).

You can set the sort mode using the Sortable method:

<%= Html.Telerik().Grid(Model)
        .Name("Grid")
        .Sortable(sorting => sorting.SortMode(GridSortMode.MultipleColumn)
 %>
