asp.net-mvc-3 - 如果为空，则 webgrid 内的自定义消息

Question

  @if (Model.ActivityCollection.Count > 0)
        {
        var grid = new WebGrid(source: Model.ActivityCollection, rowsPerPage: 12, canSort: false);   
            @grid.GetHtml(tableStyle: "webGrid",
            headerStyle: "header",
            alternatingRowStyle: "alt",
            columns: grid.Columns(
            grid.Column("EffectiveDate", "Effective Date", style: "date"),
            grid.Column("PremiumPaymentAmount", "Premium Payment Amount", style: "amount"),
            grid.Column("PaymentType", "Payment Type", style: "date")
           ));
        }
else
        {

        }

我想在上述 else 语句的网络网格内显示一条消息“未找到付款信息”。有人可以帮我解决这个问题吗？
