My signUp button event is
protected void signup_Click(object sender, EventArgs e)
{
string con = ConfigurationManager.ConnectionStrings["connection"].ConnectionString;
SqlConnection conn = new SqlConnection(con);
conn.Open();
if (selectques.SelectedItem.Text == "Write your own question?")
{
SqlCommand cmd = new SqlCommand("insert into registration values('" + username.Text + "','" + passwrd.Text + "','" + emailadd.Text + "','" + alterquestion.Text + "','" + securityanswer.Text + "')", conn);
cmd.ExecuteNonQuery();
Response.Redirect("Login.aspx");
try {
ClientScript.RegisterStartupScript(Page.GetType(), "Message", "alert('Successful Registered');window.location='login.aspx';", true);
}
catch(Exception ex)
{
}
}
else
{
SqlCommand cmd = new SqlCommand("insert into registration values('" + username.Text + "','" + passwrd.Text + "','" + emailadd.Text + "','" + selectques.Text + "','" + securityanswer.Text + "')", conn);
cmd.ExecuteNonQuery();
Response.Redirect("login.aspx");
try
{
ClientScript.RegisterStartupScript(Page.GetType(), "Message", "alert('Successful Registered');window.location='login.aspx';", true);
}
catch (Exception ex)
{
}
}
}
After registering successfully how can I show a message of Successful Registered
on login page or on the same page. I want to show the message through Popup window or messagebox.
A little UI design tip - people HATE popups. Your proposed idea would, of course, need JavaScript - some people have that disabled. Not an accessible solution. The simplest way would be to pass a parameter via GET (you could also use sessions) to login.aspx
telling it to echo an additional message at or near the top of the page saying the registration was successful, perhaps with CSS styling to make it look like a window.
But please, no alert
s and no popups. It's very poor design.
I'm pretty sure you should read up on SQL Injection too because what you're doing here is very dangerous.
SqlCommand cmd = new SqlCommand(
"insert into registration values('" +
username.Text + "','" + passwrd.Text + "','" +
emailadd.Text + "','" + alterquestion.Text + "','" +
securityanswer.Text + "')", conn);
Remove both Response.Redirect("Login.aspx");
and check.
It looks like you're posting a form when clicking the signup button, which means you'll need to render a bit of JavaScript to show the popup then to redirect, rather than doing the redirect server side.
Your other option would be to call your register action through AJAX, and if the signup is successful, again show the alert client side and also redirect client side.
移动Response.Redirect("Login.aspx");
