Question

我想做同样的想法我们对colone的mysql排序，我有表colone标题和下一个图像按钮，当我点击图像按钮我databind myrepeater并且我想在此之后更改图像按钮的图像，我这样做

protected void UserRepeater_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "country":
            break;
        default:
            string criteres = e.CommandName;
            ImageButton image = (ImageButton)UserRepeater.Controls[0].Controls[0].FindControl(criteres);
            if (image.ImageUrl == "~\\Data\\logos\\s_desc.png")
            {
                LoadSortedData(criteres, "DESC", 1);
                image.ImageUrl = "~\\Data\\logos\\s_asc.png";
            }
            else
            {
                LoadSortedData(criteres, "ASC", 1);
                image.ImageUrl = "~\\Data\\logos\\s_desc.png";
            }
            break;
    }
}

出乎意料的是，我的转发器正在被数据化，但是如果我离开了image.ImageUrl =“〜\ Data \ logos \ s_asc.png”，则图像网址没有被修改。单独没有LoadSortedData数据绑定转发器图像网址点击更改，任何想法？

                    image = (ImageButton)UserRepeater.Controls[0].Controls[0].FindControl(criteres);
                    image.ImageUrl = "~\\Data\\logos\\s_desc.png";
                }
                break;
        }
    }

编码器这个代码适用于我。
