我在我的应用程序中使用 ajax 工具包评级控制。应用程序是在 asp.net 网络表单中进行的。现在我需要更改 Metro 中的应用程序设计。我正在使用 Metro UI CSS，但在评级控制方面遇到了问题。

使用 ajax，我在后面的代码中使用了这段代码来保存数据库中的速率：

protected void Rating_Changed(object sender, RatingEventArgs e)
{
int rowIndex = ((sender as Rating).NamingContainer as GridViewRow).RowIndex;    
int accommodationId = Convert.ToInt32(gvAccommodations.DataKeys[rowIndex].Value);

        var context = new RezervacijaSmjestajaDbContext();
        var accommodation =
                 (
                    from a in context.Accommodations.ToList()
                    where a.Id == accommodationId
                    select a
                  )
                    .Single();

        accommodation.BrojOcjena++;
        double NovaOcjena = Convert.ToDouble(e.Value);
        accommodation.ZbrojOcjena = accommodation.ZbrojOcjena + NovaOcjena;
        accommodation.Rating = accommodation.ZbrojOcjena / accommodation.BrojOcjena;

        context.SaveChanges();
    }

如果我使用 Metro UI CSS 评级控件，如何在数据库中保存费率？

Metro UI 评级小部件具有 onRate 事件回调选项。

 <div class="rating" data-role="rating"  data-on-rate="func_onRate"></div>

    function func_onRate(value, star, widget){
            // do your ajax here to save changed rating 
    }
