Persist properties to aspx file on webcontrol creation

[Raymond Tellenbach via .NET 247]

Is there any way to force properties to be persisted to the aspxfile on creation of a webcontrol? To show what i mean: I want toadd the attribute 'SomeAttribute="anyvalue"' between the tags ofthe webcontrol when i drag it from the toolbox to a page. TheHTML tag of the aspx file would look something like this:<aaa:MyControl id="MyControl1" runat="server"SomeAttribute="anyvalue"></aaa:MyControl>
