>Hello,
>I'm trying to track down a memory leak in an ASP.NET application, and it has brought me to question how User Controls are disposed. Since we don't explicitly dispose of them, I'm assuming it's part of the ASP.NET page lifecycle, is that correct?

User controls get disposed automatically, but you may have to watch for circular references. if you have a user control that has a referenec back to the Page for example (should never need that given that this.Page works which is explicitly nulled) that can cause problems. Think about properties of the Page or other component that still exists in the user control that can cause problems.
