I want my code to refresh the page once its shown the success label for 3 seconds.
How can i do this in c# code?
i have this following:
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
using System.IO;
public partial class CAPTCHA_Contact : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//ImageVerification
if (!IsPostBack)
{
SetVerificationText();
}
imCaptcha.ImageUrl = "captcha.ashx?d=" + DateTime.Now.Ticks;
}
public void SetVerificationText()
{
Random ran = new Random();
int no = ran.Next();
Session["Captcha"] = no.ToString();
}
protected void CAPTCHAValidate(object source,开发者_运维问答 ServerValidateEventArgs args)
{
if (Session["Captcha"] != null)
{
if (txtVerify.Text != Session["Captcha"].ToString())
{
SetVerificationText();
args.IsValid = false;
return;
}
}
else
{
SetVerificationText();
args.IsValid = false;
return;
}
}
protected void btnSave_Click(object sender, EventArgs e)
{
if (!Page.IsValid)
{
return;
}
SetVerificationText();
//Save the content
MailMessage mail = new MailMessage();
mail.From = new MailAddress(EmailTB.Text);
mail.To.Add("name@company.co.uk");
mail.Bcc.Add("test@test.co.uk");
mail.Subject = "Web Quote";
mail.IsBodyHtml = true;
mail.Body = "First Name: " + FNameTB.Text + "<br />";
mail.Body += "Email: " + EmailTB.Text + "<br />";
mail.Body += "Telephone: " + TelephoneTB.Text + "<br />";
mail.Body += "Query: " + QueryDD.Text + "<br />";
mail.Body += "Comments: " + CommentsTB.Text + "<br />";
SmtpClient smtp = new SmtpClient();
smtp.Host = "localhost";
smtp.Send(mail);
sucessPH.Visible = true;
}
protected void Reset(object s, EventArgs e)
{
FNameTB.Text = "";
QueryDD.Text = "";
EmailTB.Text = "";
TelephoneTB.Text = "";
CommentsTB.Text = "";
txtVerify.Text = "";
}
}
So after sucessPH.Visible = true; i need to count 3 seconds and then refresh the page. This will then clear the form data and the user will also get 3 seconds to see the message to say the message was successfull.
Any ideas?
Since this is a client-side concern and not a server-side concern, you'll want to do this with JavaScript. Keep in mind that by the time the page is sent to the client all of the server-side code has completed and disposed. Trying to do this with server-side code will result in a lot of unnecessary complexity in this case.
In JavaScript you can reload the page with a delay with something like this:
setTimeout("window.location.reload()", 3000);
Well, if you're using webforms, you could use an update panel, and then use the timer component, just like this guy've done
Tutorial: How to refresh an UpdatePanel control at a timed interval
Right after sucessPH.Visible = true; add following line: ClientScript.RegisterClientScriptBlock(this.GetType(), "refresh", "setTimeout('window.location.href=window.location.href', 3000);", true);
Well.. you are in a web.. So your server can count 3, but you need the client to count 3 and then postback it to the server...
If your server only counts, then the user will not view anything..
Just make your application ajax enable, and use a timer ;)
This is the code for the page
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="3000" ontick="Timer1_Tick">
</asp:Timer>
</div>
</form>
</body>
</html>
and in the code behind you have this:
protected void Timer1_Tick(object sender, EventArgs e)
{
//do your thing when reach this tick
}
This page will refresh exactly every 3 seconds.
This is .net 4.
