A:

The reason that's happening is that your dynamic button "lbn" needs to be drawn again on post back when it's clicked because the button doesn't exist after you click it. 
Basically you just have to dynamically add the button to the page again on post back of click of that button.
I would recommend having the button already on the page but visible = false and then just showing it when you click the other button.

 Q:

Constant Password Checking?

I have read on stackoverflow the following: 
never store the users password or even a hash of the password in session or cookie data. 

I'm in the middle of making a system to check for a constant password, if it's different from one saved in a session, then force a logout; something like facebook does? When you change your password, or a password has been changed, you get logged out.
My code follows below: 
function ConstantPassword($Password)
{
    if ($_SESSION['Password']!== $Password)
    {
        
Val e As System. Web. UI.WebControls. CommandEventArgs) 
         Response. Write(e. CommandArgument) 
     End Sub 

     Protected Sub Button1_Click(ByVal transmitter As aim, ByVal vitamin e As System. EventArgs) 
         Dim btn As New LinkButton () 
         btn. ID = " lbn " 
         btn. Text = " Display Time " 
         btn. ValidationGroup = " vgDeleteSigner " 
         AddHandler btn. Command, AddressOf btnDelete_OnCommand 
         btn. CommandArgument = Now. TimeOfDay. ToString ()

 A: 

 The cause that's happen is that your dynamic push button " lbn " needs to be drawn again on mail back when it's clicked because the button doesn't exist after you chatter it. 
 Basically you barely have to dynamically add the button to the page again on post back of click of that push button. 
 I would recommend having the button already on the page but visible = assumed and then just showing it when you click the early button.
