Show alert message before redirecting to other page ASP.NET

Question

I have found a lot of examples but I don't know why these are not working for me. I have tried these but in vain.

• How to show Javascript Alert message before redirecting to same page in VB.NET?
• Javascript Alert before redirecting in ASP.NET
• Asp.net Webform Display Alert and redirect

I have also tried the following:

String message = "Session Expired! Log In Again.";
ClientScript.RegisterStartupScript(
    this.GetType(),
    Guid.NewGuid().ToString(), 
    string.Format("alert('{0}');window.location.href = 'default.aspx'", 
    message.Replace("'", @"\'").Replace("\n", "\\n").Replace("\r", "\\r")), 
    true);

and

ScriptManager.RegisterStartupScript(
    this, 
    this.GetType(), 
    "redirect", 
    "alert('Session Expired! Log In Again.'); 
    window.location='" + Request.ApplicationPath + "Account/login.aspx';", 
    true);

and

Response.Write("
<script language='javascript'>
    window.alert('Session Expired');
    window.location='~/Account/Login.aspx';
</script>");

but all of these are not redirecting to the login page just showing the alert message.

Answer 1

try this

window.location.href="Account/Login.aspx";

remove ~ operator from the path

Answer 2

Try this

Response.Write("<script language='javascript'>window.alert('Popup message ');window.location='webform.aspx';</script>");

Change location and message.

Happy coding Regards, AK.
