blackbelt web.config question - level 400

Jeffrey Palermo [MCP]

I use web.config files in many directories, and my aspx files can access the
AppSettings.
If I have a subdirectory Foo with an aspx, and Foo has a local web.config
that defines an AppSetting. My aspx in the Foo directory can properly
access this local AppSetting. I understand that web.config files are
cumulative as you go deep into the directory structure.

Here is my situation.

I have an aspx in the root of my application. I have a UserControls
subdirectory. I have a web.config file in the UserControls directory. In
my root-level aspx file, I register and user my user control in the
subdirectory. My user control's code looks for an AppSetting in the
/UserControls/web.config file, but it cannot find that configuration
information.

If the web.config AppSettings are in the web.config at the root of the
application, all is well, or if the aspx that uses the user control is
actually in the /UserControls/ directory, all is well.

So, I haven't been able to use AppSettings from a web.config file that is
local to the user control but not local (or upstream) to the aspx. Is this
by design and undoable, or is there a workaround?

Best regards,
Jeffrey Palermo

there is only one web.config per .net application (vdir). web.config files
in sub directories are ignored, unless your code reads the xml files
directly. you can turn a subdirectory into a seperate application with its
own web config by making it a vdir.

Jeffrey,
The path used to fetch the web.config is based on Request.FilePath - in
other words the path of the page being executed and not the path of the user
control. Looking at the dissassembled code, I was able to confirm this,
briefly:

System.Web.Configuration.HttpConfigurationSystemBa se actually implemenets
the GetConfig()
It calls the HttpContext's GetConfig() method
HttpContext.GetConfig calls HttpContext.GetCompleteConfig
this in turn calls GetCompleteConfigRecords and passes
HttpContext.ConfigPath
HttpContext.ConfigPath is simply a property which wraps around
HttpContext.Current.Request.FilePath

eventually down the road, the file is removed from the ConfigPath and
"web.config" is appended to it.

Karl,
That's the behavior I experienced, but thank you for confirming it
for me. The .Net docs aren't that in-depth.

In light of this, I'm going to change the web.config file that is
local to my user control to a normal .xml file that I'll read in
explicitly with my user control's code. I'll make a static config
class that'll hold the config info in application scope.

Thanks Karl.

Best regards,
Jeffrey Palermo
