Question

我在我的应用程序中使用ajax工具包评级控件。应用程序在asp.net Web表单中进行。现在我需要在Metro中更改应用程序的设计。我正在使用Metro UI CSS，我在评级控制方面遇到了麻烦。

使用ajax我在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？

Answer 1

Metro UI rating widget拥有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 
    }
