Hide your navigation buttons using DHTML when you don't need them. Imagine a page with a databound table on it showing ten rows of data. When you're at the beginning or end of the table, either the "Previous" or the "Next" button is not needed. The following code shows how to play "peek-a-boo" with the buttons. When you're at the start of the table the "Previous" button is hidden while the "Next" button is displayed and at the end of the table the "Next" button is hidden while the "Previous" button is displayed.
'Set display for Previous Button
If miPageNumber = 1 Then
cmdPrevious.style.display = "none"
cmdPrevious.style.display = ""
'Set display for Next Button
If miPageNumber = MaxPage Then
cmdNext.style.display = "none"
cmdNext.style.display = ""
