This example shows how to specify custom text for the grid buttons - "edit", "delete", "insert" etc.

<%= Html.Telerik().Grid<EditableProduct>()
        .Name("Grid")
        .ToolBar(commands =>
        {
            commands.Insert().Text("Insert product");
        })
        .Columns(columns =>
        {
            columns.Command(commands =>
            {
                commands.Edit()
                        .Text("Edit product")
                        .InsertText("Insert product")
                        .CancelText("Cancel changes")
                        .UpdateText("Update product");

                commands.Delete().Text("Delete product");
            }).Width(220).Title("Commands");
        })
%>
