Part of my aspx.cs
protected void LoginButton_Click(object sender, EventArgs e)
{
String sUserName = UserName.Text;
String sPassword = Password.Text;
Error 1 The name 'UserName' does not exist in the current context
Error 2 The name 'Password' does not exist in the current context Error 3 'ASP.default_aspx' does not contain a definition for 'Login1_Authenticate' and no extension method 'Login1_Authenticate' accepting a first argument of type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?)What am I doing wrong?
Error 1&2 -- Shouldn't you qualify the fields you need such as UserName, by say Login1.UserName instead? (I didn't check it but that sounds right to me from memory)
Error 3 -- You do need to handle the authentication event. The control is a nice shortcut, but it doesn't actually implement any business logic or do the actual logic. So you need to do this in the code behind. -- FYI that means you probably need to type out the method definition yourself in the code behind file.
