Configuration :: Can't Access AppSettings From Web.config - ConfigurationSettings.AppSettings Is Empty?

Jun 12, 2010

i have stored settings in the AppSettings section of the web.config file.

I'm trying to access these settings via System.Configuration.ConfigurationSettings.AppSettings, but the AppSettingsCollection is empty. So I can't access this settings.

The strange thing is that this is working on my development machine, but is failing on the production machine. Previous versions of the web application have also worked on the production machine. I'm not aware of any modifications that could couse this.

I have also tried using ConfigurationManager and WebConfigurationManager without success.

Put Custom AppSettings Web.config Data Into The ApplicationState?

Mar 7, 2011

I've got some custom values in the AppSettings, in my web.config file.

These values get checked upon every Request.


So if every request checks the web.config file for the value of this key, would be be smart to put this into the Application cache (eg. via the global.asax) instead of checking this value EVERY request?

I'm assuming that when we read a value from the AppSettings, the website does a physical read of the web.config file? or is this information also all read into Memory when the website starts up and all references to any appSettings information is just an inmemory read .. not a disk I/O read?

Forms Data Controls :: Display Certain Rows In GridView As Read-Only?

Apr 29, 2010

I have the following fields in an Appointment table:

ID(PK), TeacherID, DayID, TimeslotID, ParentID, StudentID, Remarks & Editable(bit, Default value=1)

I am developing an application to allow parents to book appointments to meet the child's teachers.

It is compulsory for parents to meet child's mentors, hence Appointments to meet class mentors are already pre-booked in the Appointments table.

Parents could still book appointments to meet other subject teachers. I have a column in my gridview to show parents the list of booked appointments. Parents are allowed to change the Appointment timeslot for an appointment they booked and are not allowed to change appointment time for pre-booked appointments.

Under the Remarks colum, it is stated that the following appointment is pre-booked by class mentor.

How do I make only those pre-booked rows read only since all the appointments belonging to a parent is under one GridView.

I found an example, but this is to only make the 1st 3 rows read-only and I don't think this is in VB coding. I'm usingASP.NET VB coding.

How To Read Web.config File From Javascript

Feb 8, 2011

When the user clicks on it, another .aspx page should pop up. I used the code below and it works fine. But when we deploy this .aspx page, the IP address of the target IIS server will be different. So I am thinking of saving the IP address of target IIS server in web.config file and load it into the method of Javascript code (below).Qusetion 1: Is that right way to do? If so, how I can read web.config file from Javascript?

<script type="text/javascript">
function open_win() {"http://10.999.1.86/WebUI/HistoricalRuns.aspx", "_blank", "toolbar=no, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=yes, copyhistory=no, width=1000, height=500");

Way To Use OpenExeConfiguration To Read A Different Config File

Feb 17, 2011

I'm trying to use OpenExeConfiguration to read a different config file, but I can't find any good examples.I have a windows Service and some of the config data already exists in another windows service config file on the same server, and it makes more sense to use what is already there, rather than have to maintain the same data in 2 places.

Can A Web.config Read From An External Xml File

Mar 9, 2010

I have to duplicate some settings (like connection string) between a web.config file that a WCF host uses and a web.config file that a web client uses.

In the interest of not duplicating, can I have both the web.configs read from a separate xml file? The two web.configs can be entirely in different solutions/projects so I guess this is not possible, but wanted to get other's opinion.

PS: I do understand I can use a database to store all the config settings.

VS 2008 - Read Value From Config File

Sep 13, 2011

I have code that reads a value from a config file (not web.config) given a key. It looks like this:

Public Shared Function GetCustomConfig(ByVal ValuetoGet As String, ByVal ConfigFileValue As String) As String
Dim Returnvalue As String = String.Empty
For Each KeyValue As String In AppSettings.Keys
If KeyValue = ValuetoGet Then
Returnvalue = AppSettings.Item(KeyValue).ToString
End If

Return Returnvalue
End Function

So if my config file which is named my.config has this entry: <add key="TempArea" value="c:Temp"/>I would call GetCustomerConfig("TempArea", "my.config") and the function would return "c:Temp". Most of the time this is what happens. But sometimes I get an exception: Collection was modified after the enumerator was instantiated.

Is there a better way to get the value given the key? This is code written long ago by my predecessor, and I am not sure I want to use it anymore. If I do use it, I will have to do something so that it is more reliable.

Getting AppSettings Values From Web.config In Javascript?

Apr 30, 2010



In the span's onclick handler i wrote "javascript: alert(getAppSetting('ftpuser'));" for testing, and built some alerts into the function. The first alert returns [object]. That's nice, i thought. The second alert returned 0. That's strange, because the web.config has exactly 1 of this node. So i guess that the function doesn't actually load the correct document. Has anyone done something similar ? When i don't suppy a full path, doesn't javascript assume that it should look for the file in the virtual directory of the current web application where the web.config is ?

Access To Web.config Attributes (not AppSettings)?

Mar 23, 2011

given that I can add various addributes to the stock membership provider I assume I can do the same with my own provider implementation.

<add name="MyMembershipProvider" type="Portal.Infrastructure.MyMembershipProvider"
[...] />

My question now: How do I access these values in the code? I understand that the ConfigurationManager can be used to access key value pairs in the appSettings section but this is different.
