我遇到了一些问题，不明白为什么它不起作用，我想做的是向下滚动我的未使用配置文件激活的用户列表，然后将它们添加到 UserProfile 表中给他们一个配置文件。我认为代码是正确的，但还没有完全到位。

我还是一个错误

错误

错误 1“ASP.account_userswithoutprofile_aspx”不包含“Add_Prof_SelectedIndexChanged”的定义，并且找不到接受“ASP.account_userswithoutprofile_aspx”类型的第一个参数的扩展方法“Add_Prof_SelectedIndexChanged”（您是否缺少 using 指令或程序集引用？）

首先“Default2”类型已经包含“Add_User”的定义

问题 1： 您已经在Default2页面中创建了另一个控件ID Add_User。

解决方案 1：将该控件ID正确重命名为不同的ID.

second The name 'Add_Prof' does not exist in the current context

问题 2：Add_Prof我认为您已将gridview 代码复制到Add_Usergridview 中。这就是为什么它无法识别页面中的Add_ProfGridviewDefault2

尝试这个：

设计规范： 

<asp:GridView ID="Add_User" runat="server" AutoGenerateSelectButton="True"   
BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" 
CellPadding="3" GridLines="Vertical" 
OnSelectedIndexChanged="Add_User_SelectedIndexChanged">
        <AlternatingRowStyle BackColor="#DCDCDC" />
        <FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
        <HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
        <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
        <RowStyle BackColor="#EEEEEE" ForeColor="Black" />
        <SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
        <SortedAscendingCellStyle BackColor="#F1F1F1" />
        <SortedAscendingHeaderStyle BackColor="#0000A9" />
        <SortedDescendingCellStyle BackColor="#CAC9C9" />
        <SortedDescendingHeaderStyle BackColor="#000065" />             
   </asp:GridView>

代码背后： 

 protected void Add_User_SelectedIndexChanged(Object sender, EventArgs e)
    {
        GridViewRow row = Add_User.SelectedRow;
        userlabel.Text = "Activate user"+" " + row.Cells[3].Text;
    }

建议： 请遵循正确的控件命名约定（相对名称），以免混淆。

注意：如果您可以分享Default2页面的完整设计代码，我们可以为您提供更好的帮助。
