[DotNetDevelopment] Master Page

[Mang]

I have create this application at school w/o a Master Page. Now, I try
to add a Master Page, but it just ignore my code. My application have
a log on page, so I put a break point to see if it passing anything to
the CheckLogon Page. It passing null. Do I have to recode this to pull
the input data to the CheckLogon Page?
