Question

我有一个母版页。在母版页中，我有一个页脚的UserControl。在页脚中，我有一个没有触发OnClick的按钮。在调试过程中，我看到OnClick调用的函数btnSignup_Click没有被命中。我似乎无法弄清楚代码中的错误在哪里另外我想要注意验证功能是否正常工作。

master.master

<%@ Master Language="C#" AutoEventWireup="true" Inherits="master" Codebehind="master.master.cs" %>
<%@ Register TagPrefix="xyz" TagName="Footer" Src="~/controls/footer.ascx" %>


<xyz:Footer ID="Footer" runat="server" />

footer.ascx

<%@ Control Language="C#" AutoEventWireup="true" Inherits="footer" Codebehind="footer.ascx.cs"  %>

<div>
     <asp:TextBox ID="fName" runat="server"></asp:TextBox>
     <asp:RequiredFieldValidator ID="RequiredFieldValidatorfName"  ValidationGroup="validationSignup" Display="Static" ControlToValidate="fName" ErrorMessage="First Name required" runat="server"></asp:RequiredFieldValidator>
</div>

<div class="button">
    <asp:Button ID="btnSignup"  CommandName="Button" runat="server" ValidationGroup="validationSignup" Text="Signup"  HeaderText="Please fill in all required fields before continuing." OnClick="btnSignup_Click"/>
</div>

<div class="validationSummary">                 
    <asp:ValidationSummary ID="ValidationSummary"   ValidationGroup="validationSignup" runat="server"></asp:ValidationSummary>
</div>

footer.ascx.cs

public partial class templates_site_footer : BaseUserControl
{       
    protected void Page_Load(object sender, EventArgs e)
    {
        btnSignup.Click += new EventHandler(btnSignup_Click);
    }
    protected void btnSignup_Click(object sender, EventArgs e)
    {       
        if (!Page.IsValid)
            return;

        // code to execute after button is clicked
    }
}

从Page_Load事件中删除btnSignup.Click += new EventHandler(btnSignup_Click);代码，您已经在.ASCX标记中将OnClick事件分配给按钮，而无需再次在btnSignup_Click中检查您的网页验证，您可以直接写按钮单击要执行的事件代码。

您的页脚用户控制代码背后：

protected void Page_Load(object sender, EventArgs e)
{
    //btnSignup.Click += new EventHandler(btnSignup_Click);
}

protected void btnSignup_Click(object sender, EventArgs e)
{
    if (Page.IsValid)
    {
         // code to execute after button is clicked
    }
    else
    {
         // Your page does not validated.
    }
}

单击按钮时，OnClick不会在UserControl中触发
