Default Try it out - p.613 - ListView_DataBound and Postback

Hi Imar,

I was trying to get a better understanding as to when the ListView_DataBound event is called on postback. I added a test button to the default.aspx page to compare the two postbacks.

The first postback happens via the dropdown control when user selects an album. I noticed that ListView_DataBound event is called on postback.

However, when creating a postback (by clicking the test button), I noticed that the ListView_DataBound is not called. I was confused as to why this happens?

Thank you.

Hi there,

Check out the Try It Out titled "Seeing the Page and Control Life Cycles at Work" on page 540 and further. That should answer all your questions around the different events that fire.
