（我没有在母版情景检查，请检查...）

I have a master page and based on that master page I created a page with a TextBox and two Validation controls for RequiredValidator and RegularExpressionValidator and one ValidationSummary.

when pressing the enter key in TextBox, I expected that both validator show their errorMessage on validationSummary but thats not what happening it only works when I press the button on page.

According to this page I wrapped my code with <asp:panel> and a DefaultButton attribute but it didn't solve the problem. http://www.codeproject.com/KB/aspnet/aspnet_Enter_key_problem.aspx

I want to know what the problem here is and whether there is any workaround?

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">

    **<asp:Panel runat="server" DefaultButton="EmailSend">**
    <table style="width: 100%">
        <tr>
            <asp:ValidationSummary ID="EmailValidation" runat="server" CssClass="failureNotification"
                ValidationGroup="EmailValidation" />
        </tr>
        <tr>
            <td style="width: 76px">
                Email:
            </td>
            <td class="style1">
                <asp:TextBox ID="EmailForget" runat="server" Width="244px"></asp:TextBox>
            </td>
            <td>
                <asp:RequiredFieldValidator ID="EmailRequiered" runat="server" ControlToValidate="EmailForget"
                    CssClass="failureNotification" ErrorMessage="RequiredFieldValidator" ValidationGroup="EmailValidation">*</asp:RequiredFieldValidator>
                <asp:RegularExpressionValidator ID="EmailRegular" runat="server" ControlToValidate="EmailForget"
                    CssClass="failureNotification" ErrorMessage="email required"
                    ValidationGroup="EmailValidation">*</asp:RegularExpressionValidator>
            </td>
        </tr>
        <tr>
            <td style="width: 76px">
                &nbsp;
            </td>
            <td class="style1">
                <asp:Button ID="EmailSend" runat="server" Text="send" Width="56px" ClientIDMode="Static" />
            </td>
            <td>
                &nbsp;
            </td>
        </tr>
    </table>
   **<asp:Panel>**
</asp:Content>

解决方案

Try adding this code

<script type="text/javascript">

    if (document.addEventListener) {//if Firefox
        document.addEventListener("keypress", fireFoxHandler, true);
    } else {
    document.attachEvent("onkeyup", ieHandler);
    }

    function fireFoxHandler(evt) {            
        if (evt.keyCode == 13) {
            document.getElementById("EmailSend").click();
        }
    }

    function ieHandler(evt) {
        if (evt.keyCode == 13) {
            document.getElementById("EmailSend").click();
        }
    }

</script>
