【问题描述】：
我有一个GridView 控件，在这个控件内部我使用GridView.ItemTemplate 定义了一个链接按钮。
我正在使用它在点击时打开一个新窗口。但是，当我单击链接按钮时，页面会在打开新窗口之前刷新。
点击链接按钮后如何阻止页面刷新？
当我将更新面板添加到第一个网格时，不显示弹出窗口
如果我从第一个网格中删除更新面板，网格正在刷新并且弹出窗口正在显示
我需要在不刷新网格的情况下打开一个弹出窗口
请帮我找到解决方案，因为我过去 2 天一直在处理这个问题

您可以在 aspx 和 c# 文件中发布您项目中的正确代码吗？您发布的那些代码没有任何意义，
productcodeLinkButton 没有任何 onclick 事件...很多控件没有结束标记...同样的想法是：将所有内容放在页面中updatepanel，但我们会在您更新代码后看到 -
问题是我在回发中绑定了网格所以在我的页面加载中我有这样的代码 if(!IsPostBack){ } Gridbind();因此，这需要解决方案令人耳目一新。根据我的要求，我还需要在回发中绑定网格
