我很難找到一個解決方案,單擊瀏覽器的刷新按鈕時停止表單提交。表單提交瀏覽器刷新
這是登錄窗體我有:
<asp:Login ID="EMSLogin" runat="server" OnAuthenticate="EMSLogin_Authenticate">
<LayoutTemplate>
<asp:Panel ID="Panel1" runat="server" CssClass="wrapper">
<asp:Panel ID="Panel2" runat="server" CssClass="holder">
<asp:Panel ID="Panel3" runat="server" CssClass="loginBox one_edge_shadow">
<h1>
Login Credentials</h1>
<asp:Panel ID="Panel4" runat="server" CssClass="name topmargin">
<asp:Panel ID="Panel5" runat="server" CssClass="label">
<asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">User Name:</asp:Label>
</asp:Panel>
<asp:Panel ID="Panel6" runat="server" CssClass="textBox">
<telerik:RadTextBox ID="UserName" runat="server" Height="16px" Width="165px" Font-Size="14px"
Font-Names="Arial Sans-Serif" ToolTip="Enter your valid login name" />
<asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName"
ValidationGroup="EMSLogin">*</asp:RequiredFieldValidator>
</asp:Panel>
<br class="clearfix" />
</asp:Panel>
<asp:Panel ID="Panel7" runat="server" CssClass="name topmargin">
<asp:Panel ID="Panel8" runat="server" CssClass="label">
<asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">Password:</asp:Label>
</asp:Panel>
<asp:Panel ID="Panel9" runat="server" CssClass="textBox">
<telerik:RadTextBox ID="Password" runat="server" TextMode="Password" Height="16px"
Width="165px" Font-Size="14px" Font-Names="Arial Sans-Serif" ToolTip="Enter your valid password" />
<asp:RequiredFieldValidator ID="PasswordRequired" runat="server" ControlToValidate="Password"
ValidationGroup="EMSLogin">*</asp:RequiredFieldValidator>
</asp:Panel>
<br class="clearfix" />
<telerik:RadButton ID="LoginButton" runat="server" CommandName="Login" Text="Log In"
CssClass="loginButton" Font-Size="14px" Width="100px" ValidationGroup="EMSLogin"
ToolTip="Click to log in" />
</asp:Panel>
</asp:Panel>
</asp:Panel>
</asp:Panel>
</LayoutTemplate>
</asp:Login>
而在後端:
protected void Page_Load(object sender, EventArgs eventArgs) {
log.Info("=============INSIDE Page_Load======");
DataBind();
LoginErrorWindow.VisibleOnPageLoad = false;
}
protected void EMSLogin_Authenticate(object sender, AuthenticateEventArgs e) {
log.Info("=============INSIDE EMSLogin_Authenticate======");
RadTextBox UserName = EMSLogin.FindControl("UserName") as RadTextBox;
RadTextBox Password = EMSLogin.FindControl("Password") as RadTextBox;
if (Membership.ValidateUser(UserName.Text, Password.Text)) {
FormsAuthentication.RedirectFromLoginPage(UserName.Text, false);
} else {
LoginErrorWindow.NavigateUrl = EMSApplication.Web.Utils.NavigationUtils.GetLoginErrorDialogURL();
LoginErrorWindow.VisibleOnPageLoad = true;
}
}
現在,經過一個登錄失敗,如果我按方法EMSLogin_Authenticate
再次執行的刷新按鈕。而重裝前它顯示:
我該如何解決這個問題?
