your code suggests you have your Properties defined in your page
load ?? that's wrong .. define them in your variables declaration.

don't know if this will make a difference

private void Page_Load(object sender, System.EventArgs e)
userObj.generateUser()
bla...

public string name
{
get
{
return userObj.name;
}
}

Also I have done a little project that will help you, if not confuse you,
involving asxc, customcontrols etc ... and at no point does it fail to get
to the control's variable.
It should alos give you some food for thought.

Give it five mins to allow me to zip it and upload it.
