execute ddl only on button1 click
<p>i am using a dll name Fileuploadlibrary.dll inside my bin folder</p>

<p>i think the order in which my code is working is like this
1)  dll executes first 
2) code-behind executes after</p>

<p>and it executes with evry postback on page .. i mean i have 4 buttons in my page ..it executes with any of them</p>

<p>...my aim  is to execute it only when Button1 is clicked....CAN I DO THAT???</p>
