C# - Nested GridView Not Firing Row Events?

I have a nested GridView that is placed inside a ListView. The GridView renders perfectly fine with all the entities that are bound inside its datasource.

Each record in my gridview has two buttons - 'delete' and 'edit'. The issue that I am having is that the methods wired to each of these buttons never get fired.

I think the reason for this behaviour is because my ListView's data binding happens only on the first page load, and not on every subsequent postback. As a result, when a postback happens, the events of the nested gridview are never wired up again - hence my methods are not getting fired.

Here is what my code [simplified] looks like:

[code]...

I tried modifying the above code and removing the "!IsPostBack" clause, and the events actually got fired when a button inside the GridView was clicked. However, I do not feel comfortable doing a databind on every postback and think there should be a better solution than that.
