ASP.NET - 在一个页面上单独验证两个表单？

<form id="form1" runat="server">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
    <asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" />
</form>

<form id="form2" runat="server">
    <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="TextBox2" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
    <asp:Button ID="Button2" runat="server" Text="Submit" OnClick="Button2_Click" />
</form>

protected void Button1_Click(object sender, EventArgs e)
{
    Page.Validate("validationGroup1");
    if (Page.IsValid)
    {
        // 在此处添加表单1的处理逻辑
    }
}

protected void Button2_Click(object sender, EventArgs e)
{
    Page.Validate("validationGroup2");
    if (Page.IsValid)
    {
        // 在此处添加表单2的处理逻辑
    }
}

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1" ErrorMessage="RequiredFieldValidator" ValidationGroup="validationGroup1"></asp:RequiredFieldValidator>
<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" ValidationGroup="validationGroup1" />

<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="TextBox2" ErrorMessage="RequiredFieldValidator" ValidationGroup="validationGroup2"></asp:RequiredFieldValidator>
<asp:Button ID="Button2" runat="server" Text="Submit" OnClick="Button2_Click" ValidationGroup="validationGroup2" />
