Question

I’m currently stuck. I have a webform with a button that registers or saves a record.
What i’d like to is have it display a javascript alert and then redirect to a page.
Here is the code i am using

protected void Save(..)
{   
    // Do save stuff
    DisplayAlert("The changes were saved Successfully");
    Response.Redirect("Default.aspx");
}

This code just redirects without giving the prompt Saved Successfully.

Here is my DisplayAlert Code

 protected virtual void DisplayAlert(string message)
    {
        ClientScript.RegisterStartupScript(
                        this.GetType(),
                        Guid.NewGuid().ToString(),
                        string.Format("alert('{0}');", message.Replace("'", @"\'").Replace("\n", "\\n").Replace("\r", "\\r")),
                        true
                    );
    }

Can anyone help me find a solution to this?

Thanks

You can’t do a Response.Redirect because your javascript alert will never get displayed. Better to have your javascript code actually do a windows.location.href='default.aspx' to do the redirection after the alert is displayed. Something like this:

protected virtual void DisplayAlert(string message)
{
    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);
}
