Question

我最近遇到了一个有趣的问题。在ASP.NET母版页中，我有一个登录控件和一个Google搜索框，如下所示：

    <div id="searchBox">
         <table border="0" cellpadding="0" cellspacing="0" width="100%">
                        <tr><td> <asp:TextBox ID="q" MaxLength="100" AutoPostBack="false" runat="server" onclick="ctl00$q.value=''" CausesValidation="False" Text="Google Custom Search" /></td>
                           <td align="right">
                              <asp:ImageButton ID="_btnSearch" runat="server" AlternateText="Search" validationgroup="SearchGroup"
                                 CommandName="Search" ImageUrl="~/images/search.gif" OnClick="_btnSearch_Click"/>
                           </td>
                           <td width="5px" align="right">
                           <asp:RequiredFieldValidator ID="_rfvQ" ControlToValidate="q" runat="server" validationgroup="SearchGroup" />
<asp:HiddenField ID="cx" Value="00054535354544538:kmy_69vgpnm" runat="server" />
<asp:HiddenField ID="cof" Value="FORID:11" runat="server" /></td>
                        </tr>
                     </table>      
         </div>

登录控制

<asp:LoginView ID="LoginView1" runat="server">
        <AnonymousTemplate>
           <asp:Login ID="Login" runat="server" Width="100%" FailureAction="RedirectToLoginPage" meta:resourcekey="LoginResource1">
              <LayoutTemplate>
                 <table border="0" cellpadding="0" cellspacing="0" width="100%">
                    <tr>
                       <td width="60px"><asp:Label runat="server" ID="lblUserName" AssociatedControlID="UserName" Text="Username:" meta:resourcekey="lblUserNameResource1" /></td>
                       <td><asp:TextBox id="UserName" runat="server" Width="95%" meta:resourcekey="UserNameResource2" /></td>
                       <td width="5px" align="right">
                          <asp:RequiredFieldValidator ID="valRequireUserName" runat="server" SetFocusOnError="True"
                             ControlToValidate="UserName" Text="*" ValidationGroup="Login" meta:resourcekey="valRequireUserNameResource1" />
                       </td>
                    </tr>
                    <tr>
                       <td style="height: 24px"><asp:Label runat="server" ID="lblPassword" AssociatedControlID="Password" Text="Password:" meta:resourcekey="lblPasswordResource1" /></td>

                       <td width="5px" align="right" style="height: 24px">

                       </td>
                    </tr>
                 </table>
                 <table border="0" cellpadding="0" cellspacing="0" width="100%">
                    <tr>
                       <td><asp:CheckBox ID="RememberMe" runat="server" Text="Remember me" meta:resourcekey="RememberMeResource1"></asp:CheckBox></td>

                    </tr>
                 </table>
                 <div style="border-top: solid 1px black; margin-top: 2px; padding-top: 2px">

           </asp:Login>

        <LoggedInTemplate>
           <div id="welcomebox">

        </LoggedInTemplate>
     </asp:LoginView>

如果用户在搜索文本框中输入文本并单击“搜索”按钮，则搜索工作正常。但是，如果用户在搜索文本框中输入文本并按Enter键，则会触发Login控件的验证。我想避免这种情况，因为用户只想搜索。

当用户点击搜索文本框中的输入时，如何防止激活验证。

感谢。

Answer 1

您需要了解ValidationGroups。您可能还想更改默认按钮 - link text

Answer 2

直到我理解你的问题......我想...如果你只想搜索输入设置搜索按钮作为默认按钮，同时你想要它工作并且不激活登录文本框然后设置搜索按钮的属性CauseValidation = false。如果这是你的错误，那么你可以正常工作，但你没有详细描述你的问题

主页面上的搜索文本框会触发验证错误
