Here is the list of Zone ID’s for the Blank WebPart Page (BlankWebPartPage.aspx") that is part of the Publishing Portal with MOSS 2007:

• TitleBar
• Header
• TopLeftRow
• TopRightRow
• CenterLeftColumn
• CenterColumn
• CenterRightColumn
• Footer
• RightColumn

I was in need of these and wasn’t able to find them with a simple search on Google so I wanted to share them with you.

To get a list of WebPartZone objects for a page that a webpart lives on can be done with the following code: 

foreach (WebPartZone zone in this.WebPartManager.Zones)
{ 
        this.Controls.Add(new LiteralControl(zone.ID + "<br />"));
}

Use this code in a webpart that inherits from Microsoft.SharePoint.WebPartPages.WebPart. This is a simple way to do the equivalent of a Response.Write while having the output in the webpart zone your part resides in.  It also saves you from attaching to the process and debugging with the watch or quick watch.
