No button works on main page

Question

I don't know what is happening but all of a sudden no buttons works on my main page in an asp.net c# application. I tried the same button and procedure on another page and it works perfectly. Where should be the problem? and code behind protected void Test(object sender, EventArgs e) { txtTest.Attributes["class"] = txtTest.Attributes["class"].Replace("hidden", ""); } Main page view Autentificare Utilizator: Parola: Tine-ma minte!

I moved login form on a login.aspx page and now there are no issues

Ok, it seems that using class=hidden for Login Div doesn't prevent the login form from being active and prevent other buttons from firing. Changind to visible=false fixed it but I am not happy with the resolve
