Cant Get Any Event From FormsAuthentication Sample In The Report Server ?

Hi i have used

http://msdn2.microsoft.com/en-gb/library/ms160724.aspx

to enable custom security in the report server,now custom security sample is working fine with my report server,

So bigger problem is my Software manager ask me to redesighn

UILogon.aspx page  ?

Now the bigger problem is when redesign the UILogon.aspx page 

I am having lot of problems in the sample ,thing is i cant get any button event from the

code behind it self  ?

Error is saying that

 "cannot handle Event 'Public Event Click(sender As Object, e As System.Web.UI.ImageClickEventArgs)' because they do not have the same signature."

Whats is the wrong with this ?
