避免在网格中单击LinkButton时刷新页面

本文关键字：刷新 LinkButton 单击网格 | 更新日期: 2023-09-27 18:15:06

我有一个GridView控件，在这个控件中我使用GridView.ItemTemplate定义了一个链接按钮。

我用这个打开一个新的窗口点击。但是，当我点击链接按钮时，在打开新窗口之前页面会刷新。

单击链接按钮后，如何阻止页面刷新?

当我将更新面板添加到第一个网格时，弹出窗口不显示

如果我从第一个网格中删除更新面板，网格正在刷新，弹出窗口显示

我需要打开一个弹出窗口而不刷新我的网格

请为我找到解决这个问题的方法，因为我从过去的2天里一直在做这个

请尝试在更新面板中添加模型弹出扩展器。然后它会弹出并刷新页面。这是一个示例代码。这个工作起来没有任何问题。再检查一遍
