I have 3 update panel control asp.net which updatePanel1, updatePanel2, updatePanel3. When page load first updatePanel1 will automatically load more buttons ex: button1. When click button1 in updatePanel1, that will show buttons in updatePanel2 ex: button2. When click button2 it will triggerupdatePanel3 and show data in updatePanel3 like gridview. Now, what is my problem is when click button2 all buttons in updatePanel2 lose. can you give me solution why I lose buttons in updatePanel2?
