最后一列图像按钮无法正常运行。错误消息显示：找到具有相同IDlbl的多个控件。 FindControl要求控件具有唯一ID。

The last Columns Image button cannot run correctly. The errors message show that: Multiple controls with the same ID 'lbl' were found. FindControl requires that controls have unique IDs.

推荐答案

<asp:Label ID="lbl" runat="server" Text='<%#Eval("productName") %>'>



<asp:TemplateField HeaderText = "Category">

<asp:Label ID="lbl" runat="server" Text='<%#Eval("category") %>'>



<asp:TemplateField HeaderText = "Gender">

<asp:Label ID="lbl" runat="server" Text='<%#Eval("gender") %>'>

代码中的很多标签都有相同的ID。将其标签更改为唯一ID， FindControl 应该有效。
