mvwres in custom control   

I have a  couple controls that inherits from webcontrol.

When I drop one of the controls on a new webpage
I get 

<link href="mvwres:2-Util.Ctrl.MyEmbeddedFile.css,Util, Version=1.0.0.0, 
Culture=neutral, PublicKeyToken=null" rel="stylesheet" type="text/css" />

in the head.

I am not sure why the other controls the same thing doesn't happen.

What causes the creation of the mvwres?
What would happen if this page used a master page (i.e. no head section)?

thanks,

Hi Chuck,

I have no past experience on this mvwres stuff, I also searched internally 
and didn't find much information on this. Would you please tell me how to 
reproduce this issue on my side? After I reproduced it, I will consult 
within our internal discussion list to see if anyone can explain more about 
it. Thanks.

I wish I could reproduce it. Some ctrls I get it some I don't.
There is some discussion on:
www.nikhilk.net/WebResourceAttributeAtDesignTime.aspx

Also it looks like the guys in the Ajax tool kits implements it.

RE: mvwres in custom control   

Hi Chuck,

Sorry for delayed reply.

I'm including the reply from ASP.NET team about this mvwres custom protcol 
here:

<quote>
ASP.NET doesn't use the custom protocol. Only Visual Studio and other 
designer tools use it. There is an interface, 
System.Web.UI.IResourceUrlGenerator that is used when a control wants to 
create a URL to an embedded WebResource. At runtime the ASP.NET URL 
generator creates links in the form 
~/Site/WebResource.axd?d=<data>&t=<timestamp>. At design time the tool's 
(Visual Studio) URL generator creates links in whatever format it wants. In 
the specific case of VS it uses a custom protocol handler called "mvwres" 
with a custom URL format to generate those URLs.

Whether at runtime or design time, the URLs are used to locate and load the 
specified resource, whether it's a JS files, CSS file, HTML, GIF, etc. 
Without the custom mvwres protocol the resources wouldn't be able to load 
at design time.

Hope this helps.
