我有GridView控件，在此控件内部我使用GridView.ItemTemplate定义了一个链接按钮。
我使用它在点击时打开一个新窗口。但是，当我点击链接按钮时，页面会在打开新窗口之前刷新。
单击链接按钮后如何停止刷新页面？
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，则网格正在刷新，弹出窗口正在显示
我需要在不刷新网格的情况下打开弹出窗口
请我找到解决方案，因为我已经过了2天的工作

检查DataGrid1.Datsource中是否有DataGrid1.Databind();和onPage_Load()
因为当你按下按钮时会调用它。
DataGrid1.DataSource = ...;与DataGrid1.DataBind();结合使用，可将gridview中的所有值更新为已定义列表中的值。
这意味着当你在onPage_Load()中拥有它时，它将刷新gridview。
答案 1 :(得分：0)
这里的结构：
首先，如果您使用的是母版页，请将其置于页面顶部，ContentPlaceHolder1下方，如果您不是
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"></ajaxToolkit:ToolkitScriptManager>
接下来，我们创建一个UpdatePanel，页面中的EVERYTHING将放在INSIDE这个UpdatePanel中（你可以有其他UpdatePanel，但这是外部的）这将确保页面不会刷新/重新加载任何点击事件（{此外部UpdatePanel不需要{1}}。使用<trigger>作为ModalPopupExternder的TargetCOntrolID instaed of button。
HiddenField不要使用UpdatePanel.Update（）函数，如果要更新gridview，请更新数据集并调用Gridview.Databind（）方法。
如果你想在ModalPopupExtender中使用其他UpdatePanel，只需将所有内容都放在Panel中，但这次你需要<asp:UpdateProgress ID="UpdateProgress1" DisplayAfter="10" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate>
<div style="position: absolute; visibility: visible; border: none; z-index: 100; width: 100%; height: 100%; background: #999; filter: alpha(opacity=80); -moz-opacity: .8; opacity: .8;">
<img src="http://www.ajaxload.info/images/exemples/29.gif" style="top: 50%; left: 50%; position: relative;" />
</div>
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
//all your contents will be here
//Your DataGrid1 with LinkButton inside...
<AjaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" BackgroundCssClass="modalBackground" CancelControlID="cancel" TargetControlID="HiddenField1" runat="server" PopupControlID="pnlpopup"> </AjaxToolkit:ModalPopupExtender>
<asp:HiddenField ID="HiddenField1" runat="server" />
// Your pnlpopup Panel
</ContentTemplate>
<Triggers>
</Triggers>
</asp:UpdatePanel>
来获取这个UpdatePanel中的按钮（而不是取消/关闭弹出按钮）
