This is a normal effect for Javascript alert ,
try the window.Open Method to create your own popup ,
or look for jQuery popups.

Wait......!!
I got the problem
The alert starts before page loads so what i found as the work around is.
modify <body> tag as follows
Then in the Code Behind\C# file add this in PageLoad event.
This waits until the all the html is loaded and only then it will alert you.
I think the script manager puts the script in the <head> tag which means the script will load immediately which is not what you wanted .
I think we are Winning!

Then modify like follow
void btnLogin_Click(object sender , EventArgs e)
{
//Database search for user.
if(UserValid)
myBody.Attributes.Add("onload","alert('hello');");
else
myBody.Attributes.Add("onload","alert('enter password & Username');");
}

That's weird because onload works after html page has been loaded ,
As you can see here what i mean
http://stackoverflow...after-page-load
have you fixed this ??
