Linkbutton打开一个模式弹出窗口，但其弹出窗口立即关闭

我正在创建一个需要在模态弹出窗口中打开一个可配置页面的asp链接按钮。Linkbutton打开一个模式弹出窗口，但其弹出窗口立即关闭

打开模式弹出窗口，但立即关闭。我把href＃但它不工作。

如果我检查生成的HTML是：

<a id="ctl00_ctl38_g_69332c4e_2a87_4bb4_ad70_f7debbd14e91_LnkButton" onclick="OpenModalPopup('www.google.com', '800', '300');" href="javascript:__doPostBack('ctl00$ctl38$g_69332c4e_2a87_4bb4_ad70_f7debbd14e91$LnkButton','')">

ASCX或web部件文件

<script type="text/javascript"> 
    function OpenModalPopup(pageUrl, widthParameter, heightParameter) { 
     var options = { url: pageUrl, width: widthParameter, height: heightParameter, showClose: true }; 
     SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options); 
    } 
</script> 
<asp:LinkButton CssClass="pwcLinkButton" ID="LnkButton" runat="server" href="#"></asp:LinkButton>

的.cs

namespace xx.SP.xx.WebParts.VisualWebParts.LinkButton

更改您的代码，看看是否它帮助：

LnkButton.Attributes.Add("onclick", "OpenModalPopup('" + Link.ToString() + "', '" + WidthPopup.ToString() + "', '" + HeightPopup.ToString() + "'); return false;");

看来，它不是你的弹出窗口关闭，但你的链接导致回发，所以页面刷新。如果您的链接onclick处理函数返回false，它将被浏览器解释为取消链接clic，因此不会导致回发。所以改变这一行为：

LnkButton.Attributes.Add("onclick", "OpenModalPopup('" + Link.ToString() + "', '" + WidthPopup.ToString() + "', '" + HeightPopup.ToString() + "'); return false;");

应该做的伎俩。
