Oh, I wan't clear - the web pages are created in VS, but I edit them afterwards in Dreamweaver. Make sure you do not use the grid layout option.... Just in case I added controls and forgot to declate them I use this code:

		private void DumpControls(Control c, int depth)
		{
			//Usage sample: DumpControls(this.Page, 0);


			if (c.ID != null)
			{
				for (int a = 1; a < depth; a++)
				{
					Debug.Write("");
				}
				Debug.WriteLine(c.ID, c.ToString());
			}
			foreach (Control subControl in c.Controls)
			{
				DumpControls(subControl, depth + 1);
			}
		}

It dumps a list of all instantiated control to the output window in debug mode.
