我有一個Web窗體頁面,其中包含一個標籤和兩個文本框,我想在頁面的代碼後面訪問文件,但是當我在代碼中調用文本框時在文件後面,紅色的波浪線顯示在標籤和文本框的下面。我已經嘗試了類似問題中提到的解決方案(重新生成設計器文件,確保在其他頁面中沒有多個文本框/標籤具有相同的名稱,創建一個新的aspx頁並重新編寫代碼),但沒有一個已經解決了這個範圍問題。這段代碼昨晚編譯得很好,從那時起我就沒有改變代碼,也沒有編譯。從代碼隱藏文件中訪問文本框,標籤等
我對C#比較陌生,所以我可能會錯過一些非常明顯的事情,對此我很抱歉。
在Login.aspx.cs:
protected void btnCreateUser_Click(object sender, EventArgs e)
//this is called in an asp:button's OnClick
{
string loginUsername = txtBxUsername_Login.Text;//red line on txtBxUsername_Login
string loginPassword = txtBxPassword_Login.Text;//red line on txtBxPasswprd_Login
if (loginUsername != null && loginUsername != "" & loginPassword != null && loginPassword != "")
{
WebSecurity.Login(loginUsername, loginPassword, false);
lblLoginResponse.Text = "TO DO: Proper login response";//red line on lblLoginResponse
}
}
在爲Login.aspx:
<asp:Content ID="BodyContent" ContentPlaceHolderID="PageContent" runat="server">
<div class="row">
<div class="content-large">
<%-- This section tag contains all account validation controls, buttons, textboxes and labels --%>
<section id="loginForm">
<div class="form-horizontal">
<h2><%: Title %></h2>
<h4>Use a local account to login: </h4>
<hr />
<asp:PlaceHolder runat="server" ID="ErrorMessage" Visible="false">
<p class="text-danger">
<asp:Literal runat="server" ID="failureText" />
</p>
</asp:PlaceHolder>
<div class="form-group">
<div class="text-box-container">
<asp:Label ID="lblUsername" runat="server" Text="Username"></asp:Label>
<asp:TextBox ID="txtBxUsername_Login" runat="server"></asp:TextBox>
</div>
</div>
<div class="form-group">
<div class="text-box-container">
<asp:Label ID="lblPassword" runat="server" Text="Password"></asp:Label>
<asp:TextBox ID="txtBxPassword_Login" runat="server"></asp:TextBox>
</div>
</div>
<div class="form-group">
<asp:Button ID="btnRegister" runat="server" Text="Log in" OnClick="btnLogin_Click" />
<asp:Label runat="server" ID="lblLoginResponse" />
</div>

我在控件運行時將控件添加到頁面時會出現此問題。後面的代碼不會自動生成。檢查後面的設計器代碼。控制屬性在那裏自動生成? – 2014-10-01 00:07:49
在代碼中,您使用txtBxPassword_Login.but在其用戶名中使用txtBxPassword – Seminda 2014-10-01 00:12:15
檢查或交叉驗證是否使用/映射Login.aspx.designer.cs文件與項目中的任何其他設計器頁面。在整個項目中搜索Login.aspx.cs – Malcolm 2014-10-01 06:43:01
