我有一个 asp.net 网页表单页面，它也使用母版页。

这是一个简单的页面，显示一些文本并有一个表格，该页面还允许用户上传 .doc、.docx 和 pdf 格式的简历。

这段代码的问题是我由于某种原因无法触发 <asp:Button ID="btnUploadCV" runat="server" Text="Upload" CssClass="btnUpload" onclick="btnUploadCV_Click"/>

代码背后

    protected void btnUploadCV_Click(object sender, EventArgs e)
    {

// code is here
    }

到目前为止，我无法弄清楚是什么阻止了里面的任何按钮触发。是的，我什至放了一个简单的按钮来测试，即使它没有触发。

在此处输入图像描述

我不确定是验证还是更新面板造成了问题。

必填字段验证器可能会咬你。只需将属性' Causevalidation ="false" '添加到您的按钮，它就会触发。您可以使用 if Page.IsValid 处理验证服务器端

<asp:Button ID="btnUploadCV" runat="server" Text="Upload" CssClass="btnUpload" onclick="btnUploadCV_Click" CausesValidation="false" />

服务器端

protected void btnUploadCV_Click(object sender, EventArgs e)
{
  Page.Validate();
if (Page.IsValid == true)
 {

 //  your code  here

   }
}

更新

我不确定您的按钮发生了什么。然后，如果一切都失败了，请进行蛮力攻击以使回帖像这样。

<asp:Button ID="btnUploadCV" runat="server" Text="Upload" CssClass="btnUpload" onclick="btnUploadCV_Click" CausesValidation="false" onClientClick='forcePostBack()" />

**Javascript**
function forcePostback(){
 __doPostBack('<%#btnUploadCv.UniqueID %>','');

 }

您需要在更新面板中添加Triggers之后。ContentTemplate

<Triggers>
   <asp:PostBackTrigger ControlID="btnexport" />
</Triggers>
