Accessing appSettings syntax- Hardcoded value replaced with appSettings

Currently I have a value that is hardcoded and I need to change it to a setting found in the web.config. I have a web.config file with a Key <add key="AVLLayer" value="AVL"/> I need to access this in the Default.aspx. See below

In web.config I have
 
<appSettings>
<add key="AVLLayer" value="AVL"/>
</appSettings>
 
in Default2.aspx I have 
 
 <esri:MapResourceItem Definition="&lt;Definition DataSourceDefinition=&quot;testweb&quot; DataSourceType=&quot;ArcGIS Server Local&quot; Identity=&quot;&quot; ResourceDefinition=&quot;(default)@AVL&quot; DataSourceShared=&quot;True&quot; /&gt;" 
                    DisplaySettings="visible=True:transparency=0:mime=True:imgFormat=PNG8:height=350:width=600:dpi=96:color=white:transbg=True:displayInToc=True:dynamicTiling=False" Name="AVL" LayerDefinitions=""/>
 
 
I need to replace the Name="AVL" with System.Configuration.ConfigurationSettings.AppSettings("AVLLayer") or something close but I can't get the syntext to work.

No, that does not work...I found this on the ESRI Forums in case anyone else needs it... the Solution is that you need to create you Resource Items in the code behind dyamiclly.

Message I generally create my resources on the fly with the following code. Hope it is of some help. 
 
Private Sub SetupMapResources() 
' setup map resource service names 
Dim primarySvcName As String = ConfigurationManager.AppSettings("PrimaryServiceName") 
 
' setup primary resource 
Dim mapResource1 As New MapResourceItem 
Dim gisResourceDef As New GISResourceItemDefinition 
With gisResourceDef 
.DataSourceDefinition = "LocalHost" 
.DataSourceType = "ArcGIS Server Local" 
.Identity = "" 
.ResourceDefinition = "(default)@" & primarySvcName 
End With 
mapResource1.Definition = gisResourceDef 
mapResource1.Parent = MapResourceManager1 
mapResource1.Name = "FCWO" 
mapResource1.InitializeResource() 
 
' assign resources to map 
MapResourceManager1.ResourceItems.Add(mapResource1) 
MapResourceManager1.Refresh() 
Map1.InitializeFunctionality(mapResource1) 
End Sub

This ended up being ESRI control issue and not asp as I origianlly thought...Thanks for the post though

Well I did answer the question and we certainly could have worked out any config errors had that been the issue. And there seems to be some useful information here from both the asker and myself that belongs in the PAQ.
