I'm going to guess that the event handler for the addRoles button (or is it addButton Button?) fires when you refresh the page only if you press the button before refreshing the page (meaning on the previous page view, the button was pressed). If this is correct: This is a common problem for page developers. When you hit refresh, the posted data is posted back; that posted data contained information telling the page to execute the button's event handler so when you hit refresh the event will be fired again. There are several ways to overcome this, the simplest being to check the datasource to see if the data being inserted is already in the datasource, if not insert it, if so don't insert it.

The menu control is rendered to a HTML page.:-D

.net 2005 uses a different compilation mode, called dynamic compilation. In .net2003, the compilation was handled by Visual Studio and the result was a dll in the bin folder. With .net2005, ASP.NET handles the compilation "on-the-fly" and therefore there is no dll. But there is a new add-in (now part of Visual Studio 2005 SP1) called Web Application Projects which allows you to use the same compilation mode used in .net2003; a dll is compiled by VS and placed in the bin folder. One major reason for the creation of this add-in was to assist in the upgrading of .net2003 projects to .net2005. http://ASP.NET has an article regarding the Web Application Projects on there home page.
