I've been studying dotnet from last 2 years but
couldn't start to build a singe ASP.net application. Whenever I try
to start lot of questions popup in mind and I give up always.

I made an application before in ASP and want to build the same in
ASP.net. What stops me is where and how to start. In my previous
application I had a main page  that was consisting of a menu and when
we click any of the links on that menu, if you are not logged than
it brings up a login page. Now it confuses me whether up use the
same ASP style text boxes and button for login page or use the login
web control. If I need to use login control then can I customize, if
yes then how and where I can get a good example.

Then the other question that pops up is about the menu that I had in
ASP, whether I have to make the same using html tables and
hyperlinks or use the new site navigation or menu control, again can
I customize them and how to insert dynamic information.

In one page in ASP I was having dynamic creation of html rows to
enter details. I was using JavaScript to create a new row for a html
table and that table columns was having text boxes so I used these
text boxes to enter the data. How to implement this in dotnet. Do I
have to use gridview or some other control and will I do have full
control on it.

Don't you think these questions will really make to stop  to do
ASP.net before starting and this is what makes me crazy? Kindly help
me with examples and a very big thank in advance.
