推荐答案

虽然你已经清楚地提到图像按钮不在gridview或datalist之类的任何控件内，但我仍然会问，你确定吗？

Although you have clearly mentioned that the image button is not inside any control like gridview or datalist, still I'll ask, are you sure?

<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="images/icon-continue-shopping-4-150x49.jpg" PostBackUrl="<%#"Order_Details.aspx?pid="+Eval("ProductID") %>" />

什么 Eval（ProductID）应评估为？



只是为了测试你可以尝试用

What Eval("ProductID") should evaluate to?

Just for a test you can try replacing the above snippet with

<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="images/icon-continue-shopping-4-150x49.jpg" PostBackUrl="Order_Details.aspx?pid=1" />

它应该重定向到 Order_Details.aspx ，pid = 1，你写的逻辑将被执行。



我相信，你想让这个图像按钮重定向到其他地方。

如果你想做的话你也可以使用 OnClick 事件它的另一种方式。



如果你的问题没有解决，请告诉我:)）

It should redirect to Order_Details.aspx with pid=1 and the logic you have written will be executed.

I am sure, you want this image button to redirect somewhere else.
You can also use OnClick event if want to do it other way.

In case, your problem is not resolved, please let me know :)
