]，因此我不想“弄脏”我的项目。提前谢谢你 只需调用代码隐藏中的函数即可构建图像URL:
protected static string BuildItemImageUrl(string id)
{
if (id.StartsWith("111"))
{
return "~/images/notebook.jpg";
}
if (id.StartsWith("222"))
{
return "~/images/pendrive.jpg";
}
if (id.StartsWith("333"))
{
return "~/images/keyboard.jpg";
}
return "~/images/unknown.jpg";
}
从图像
控件的图像URL
的数据绑定语句调用函数：
<asp:Image ID="ItemImage" runat="server"
ImageUrl='<%# BuildItemImageUrl(Eval("Id", "{0}")) %>'
/>
如果您有关于如何修改代码以执行某项操作的问题，请提供您的代码，这样答案就不必从头开始，在收到答案时会更有用。更新问题以包含代码，请不要将其作为注释发布（出于可读性目的）。不起作用。此外，它还表示“警告元素‘Image’不是已知元素。如果网站中存在编译错误，或者Web.config文件丢失，则可能会发生这种情况。”。必须将图像控件放置在何处？@Fabrizio:它需要位于ItemTemplate
/AlternatingItemTemplate
中的某个位置。您需要将其放入
标记中，使其显示在表中。
