I would like to do different button when there is null(no image) in the database. But, it shows two buttons instead of one button only. Can you guys help me? I tried at the frontend only. If there are solutions to do at the backend, please share some codes.

What I have tried:

<a href="#" id="ImageButton2" class="btn btn-success" visible='<%# If(IsDBNull(Eval("ImagePic")), True, False)%>'>No Image</a>
