我是 C# 的 asp.net 新手，我需要更新 Gridview 中的一行，但我必须使用 AJAX 中的 ModalPopupExtender 和我的表的某些字段，必须是强制性的，所以，我开始使用这个控件以这种形式：首先我将一个按钮置于显示模式“none”中，作为更新面板的触发器，在gridview中我放置了一个按钮名称“Edit”，它显示了ModalPopupExtender代码，但我的麻烦来了，当我放了RequiredFieldValidator，ModalPopupExtender 没有显示，这是我的代码，请帮助我，还有一件事，我不能使用Javascript。

    <asp:Button ID="btnCancel" runat="server" Text="Cancel" />
</ContentTemplate>
</asp:UpdatePanel>

这是我背后的代码

protected void btnEditar_Click(object sender, EventArgs e)
{
    Button btndetails = sender as Button;
    GridViewRow gvrow = (GridViewRow)btndetails.NamingContainer;
    tbNombre.Text = gvrow.Cells[1].Text;
    this.ModalPopupExtender1.Show();
}

这个今天为我指出了正确的方向，所以我想我会发布一个实际的代码解决方案。正如上面在评论中提到的，关键是向所有RequiredFieldValidator 控件添加一个ValidationGroup标签，这样您就可以控制何时应用验证 -
