You can use Validation Group.

Sample code here:

<body>
    <form id="form1" runat="server">
    <div>
        <h1>Group1</h1>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox1" ValidationGroup="group1"></asp:RequiredFieldValidator>
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox2" ValidationGroup="group1"></asp:RequiredFieldValidator>

        <br /><br />
        <h1>Group2</h1>
        <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox3" ValidationGroup="group2"></asp:RequiredFieldValidator>
        <asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ErrorMessage="RequiredFieldValidator" ControlToValidate="TextBox4" ValidationGroup="group2"></asp:RequiredFieldValidator>

        <br /><br />
        <asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="group1" />
        <asp:Button ID="Button2" runat="server" Text="Button" ValidationGroup="group2" />
    </div>
    </form>
</body>
