如何在延迟后重定向到另一个页面

Question

我的网页里面有一个登录框 UpdatePanel

<asp:UpdatePanel runat="server" ClientIDMode="Static" ID="upSign" UpdateMode="Conditional">
    <ContentTemplate>
        <div class="dvHolder hidOverflow clearfix">
            <input id="txtSUser" type="text" name="SUsername" value="" placeholder="Username" runat="server" />
        </div>
        <div class="dvHolder hidOverflow clearfix">
            <input id="txtSPass" type="password" name="SPassword" value="" placeholder="Password" runat="server" />
        </div>
        <div class="dvHolder hidOverflow clearfix setTextRight">
            <asp:Button ID="btnSignIn" ClientIDMode="Static" runat="server" Text="Sign In" OnClick="btnSignIn_Click" />
            <asp:Label runat="server" Text="" ID="lblSSuccess" ClientIDMode="Static" CssClass="lblMsgSuccess" />
        </div>
    </ContentTemplate>
</asp:UpdatePanel>

一旦用户成功验证,我想在延迟后显示一条消息并重定向(假设为5秒).我有以下代码,但它没有重定向:

public void btnSignIn_Click(object sender, EventArgs e)
{
    lblSSuccess.Text = "We found you, now redirecting...";
    lblSSuccess.ForeColor = ColorTranslator.FromHtml("#037203");
    Session["UseIsAuthenticated"] = "true";

    Response.AppendHeader("Refresh", "5;url=homepage.aspx");
}

消息已更新,但页面由于某种原因未重定向.

请帮我解决这个问题.

您可以编写一个Javascript带延迟的块,并使用此代码重定向到该页面

public void btnSignIn_Click(object sender, EventArgs e)
{
    lblSSuccess.Text = "We found you, now redirecting...";
    lblSSuccess.ForeColor = ColorTranslator.FromHtml("#037203");
    Session["UseIsAuthenticated"] = "true";

    ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "redirectJS",
    "setTimeout(function() { window.location.replace('homepage.aspx') }, 5000);", true);
}
