Question

我在这里看到的各种问题与这个问题非常接近，但似乎没有一个问题符合这一特定情况。

描述：我在主页面中有ID和密码字段以及登录按钮。这些都在“LoginValidationGroup”中，它们工作正常。

现在，在Default.aspx中，我有一个电子邮件TextBox和提交按钮，它们位于“NotifyMeValidation”组中，它们也可以工作，但是如果你按下回车键而不是提交按钮则不行。提交按钮工作正常 - 输入密钥......不是那么多。

Enter键导致验证在LoginValidationGroup上发生，即使TextBox设置为CausesValidation =“true”，并且它位于NotifyMeValidation组中。

我保证人们会在该框中输入电子邮件并按Enter键。我会！！！当他们这样做时，他们会在顶部看到一个标注气球，告诉他们需要用户ID。

我的错误是什么？如果我需要发布实际代码，我可以这样做。

实际上，让我继续这样做。

来自Default.aspx：

<asp:RequiredFieldValidator 
    runat="server"
    ValidationGroup="NotifyMeValidation"
    ID="EmailRequiredValidator"  
    ControlToValidate="SenderEmailTextBox"
    ErrorMessage="Email is Required" 
    Display="None" />
<ajaxToolkit:ValidatorCalloutExtender 
    runat="Server"
    PopupPosition="Left"
    ID="EmailRequiredValidatorExtender"
    Width="185px"
    TargetControlID="EmailRequiredValidator" 
    WarningIconImageUrl="/Images/warning.gif" />
<asp:Label ID="SenderEmailLabel" runat="server" ssociatedControlID="SenderEmailTextBox" EnableViewState="false" Text="Email:"></asp:Label>&nbsp;&nbsp;
<asp:TextBox ID="SenderEmailTextBox" runat="server" ValidationGroup="NotifyMeValidation" Width="350" BackColor="#cccccc" CausesValidation="true"></asp:TextBox>
<br /><br />
<asp:Button ID="SubmitButton" runat="server" ValidationGroup="NotifyMeValidation" EnableViewState="false" CssClass="submit" Text="Send" CausesValidation="true" OnClick="btnSubmit_Click" />

从母版页：

<asp:Label CssClass="LoginHeading" ID="UserNameLabel" runat="server" AssociatedControlID="UserNameTextbox">UserName:&nbsp;</asp:Label>
<asp:TextBox CssClass="LoginTextBox" ID="UserNameTextbox" runat="server"  ValidationGroup="LoginValidation" CausesValidation="True"></asp:TextBox>&nbsp;
<asp:Label CssClass="LoginHeading" ID="PasswordLabel" runat="server" AssociatedControlID="PasswordTextbox">Password:&nbsp;</asp:Label>
<asp:TextBox CssClass="LoginTextBox" ID="PasswordTextBox" runat="server" TextMode="Password" ValidationGroup="LoginValidation" CausesValidation="True"></asp:TextBox>&nbsp;
<asp:Button CssClass="LoginHeading" ID="LoginButton" runat="server" Text="Button" CommandName="Login"  ValidationGroup="LoginValidation" CausesValidation="True" onclick="LoginButton_Click" />

Answer 1

尝试在每组控件周围添加<asp:Panel>，并在用户点击 Enter 时将DefaultButton property设置为您要点击的按钮的ID。

Answer 2

只是为了解释这里发生的事情，当您在文本框中按Enter键时，将触发aspx的默认按钮。要处理这个问题，你可以在文本框上单击回车键时触发一些jQuery代码，然后这段代码将执行你需要的特定按钮的点击。 Check this

除了Enter键之外，asp.Net ValidationGroup正确验证
