推荐答案

您不能将数据绑定表达式与静态值组合在一起。



尝试：

You can't combine a data-binding expression with a static value like that.

Try either:

<asp:Image ID="Image1" runat="server" ImageUrl='<%# "~/Images/logo/" + Eval("logo") %>' />
<asp:Image ID="ImageUrl" runat="server" ImageUrl='<%# "~/Images/cpu/" + Eval("pic") %>' />

或：

or:

<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("logo", "~/Images/logo/{0}") %>' />
<asp:Image ID="ImageUrl" runat="server" ImageUrl='<%# Eval("pic", "~/Images/cpu/{0}") %>' />

这样的事情应该会有所帮助：

Something like this should help:

<asp:ListView id="ListView1" runat="server" onitemdatabound="ListView1_ItemDataBound">
...
...
<asp:Image id="Image1" runat="server" />
...
...
</asp:ListView>

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e){
  Image img;
  if (e.Item.ItemType == ListViewItemType.DataItem){
    img=(Image)e.Item.FindControl("Image1");
    if(img!=null){
      System.Data.DataRowView rowView = e.Item.DataItem as System.Data.DataRowView;
      img.ImageUrl=string.concat("/Images/logo/",rowView["logo"].ToString());
    }
  }
}

希望它有所帮助。
