更新面板内的gridview不起作用

Question

我在 GridView 中有一些图像按钮，当我单击这些图像按钮时，整个页面都会刷新。我只想在单击该图像按钮而不重新加载整个页面时触发该图像按钮事件。我也用过更新面板。 我从两天开始就面临这个问题，现在我需要帮助，我无法做到这一点。

这是我的 .aspx

Answer 1

尝试将更新模式更改为“始终”。目前，Async 方法与“更新按钮”绑定在一起。

Answer 2

尝试像这样在内容模板结束标记之后放置触发器标记... ...</ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="updatebutton" EventName="Click" /> </Triggers>
