Configuration :: How To Read Configuration Settings Of Web.config Using Javascript
Apr 30, 2010
Web.config is the main settings and configuration file for an ASP.NET web application. The file is an XML document that defines configuration information regarding the web application. The web.config file contains information that control module loading, security configuration, session state configuration, and application language and compilation settings. Web.config files can also contain application specific items such as database connection strings
Example 1:
<!-- This is an example Web.config file -->
[Code]....
In this article, we will see how to read the configuration settings in the web.config using 'JavaScript'.
Step 1: Create a new ASP.NET website. Add a button control to the Default.aspx.
Step 2: Right click the project > Add New Item > Web Configuration File
Add the following sample entry to the appSettings section in the web.config between the <configuration> tag as shown in the example 1:
<add key="var1" value="SomeValue"/>
Step 3: To read these entries using JavaScript, add the following script in the <head> tag of your Default.aspx page as shown below:
<head runat="server">
<title></title>
<script type="text/javascript">
function ReadConfigSettings()
{
var v1 = '<%=ConfigurationManager.AppSettings["var1"].ToString() %>'
alert(v1);
}
</script>
</head>
Step 4: Call this function on a button click and display the values of the configuration settings
<input type="button" value="Get" onclick="ReadConfigSettings();" />
That's it. Run the application and click the button. The value of the key in the appSettings will be displayed in the alert window. I hope you liked this short article.

I'm starting to consider creating a class library that I want to make generic so others can use it. While planning it out, I came to thinking about the various configuration settings that I would need. Since the idea is to make it open/shared, I wanted to make things as easy on the end user as possible. What's the best way to setup configuration settings without making use of web.config/app.config?

I am designing a web application for Leave Application of our faculties. There is a form in my website which represent the existing paper-back leave application form. Users(faculties) have to fill-up this web form and after validation an email will be send to the email address of our principal/hod. I hope that email address(s) will be provided to our group members. Now I want to know that what will be the required configuration of the web.config file? I found this blog ScottGu's Blog. Here the given configuration is:
[Code]....
But I think this is not acceptable for my project as the smtp from="test@foo.com", userName, password are unknown to me. So what should I do. Am I able to understand my requirement to you?

I've been thinking about this for a couple days but still would like some feedback on the best way to go about this:
I have multiple sites (domains) that will be running the same code. However, there are a couple settings I have in the appsettings web.config file which are relative to each site. (ie: defaultSiteTitle, emailFromAddress, etc).
I would like to deploy this application in only one location (folder) and point the domains in IIS to that one directory.
To do this, I believe I cannot use the web.config file to hold these settings...
So, I decided to make a SiteSettings.xml file and load the site settings in there:
<sites>
<oSite domain="abc.com" defaultSiteTitle="This is Site ABC" emailFromAddress="info@abc.com" />
<oSite domain="xyz.com" defaultSiteTitle="This is Site XYZ" emailFromAddress="info@xyz.com" />
</sites>
So when I need to access the site settings I just call a function in my datalayer that reads this xml file and via the httpRequest I pass it it determines which site settings to use.
Okay, that works when I call it from a page where I have the httpRequest...
Howver, now when I'm into some business layer functions say sendEmail and I need to find the emailFromAddress from the SiteSettings.xml file, I don't have the httpRequest. I know I could probably hack something together and pass it someway...
But I'm trying to figure out the best way to do this...
I don't really want to store it into session.
Is it possible to tell IIS what web.config file to look at, if I had multiple web.config files? (I don't think this is possible).

This is a general question and is not about any particular issue that I am facing right now.As configuration settings in the child level can override the ones in parent level,errors can occur when you have 2 web.config files one redefining configuration settings that you cannot override such as authentication or session state.Issue happens when you have authentication / session state set on the lower level web.config and also in higher level web.config. Is there any other configuration settings like these ?

I have few settings which I could place in a separate XML file and have them accessed in the Web app. Then I thought (thinking of one additional file to deploy), why not have them in the web.config itself. However, just because I need to have custom nodes, I can not have the settings under . So, I am thinking of creating a custom config handler following this. Would that be better than having a separate XML file? Is It going to be an overkill or performance wise? Is there a better way to go?

We are experiencing some strange behaviour on one of our ASP.NET web servers (Windows 2003 64-bit). After some activity, two third-party controls are unable to run correctly. One is log4net (it does not write error messages out) and the other is a menu control (it displays eval message instead of picking up its license). The one common thread is that both controls pick up their config from external config files (linked to from web.config).
Just wondering if anyone has any thoughts on this or experienced this in any way. Is it related to file/folder rights? The server has been running fine for a while and just started exhibiting this behaviour. Perhaps it occurs around the time the worker processes are recycled.

<asp:sqldatasource id="DS" runat="server" connectionstring="<%$ ConnectionStrings:MY_CONNECTION %>"
Selectcommand ="Select * from [10.10.10.10].dd.dbo.table">
The connection string is taken from web.config.
I want to take a value from the web.config -> app settings via asp tag.
The reason is that inside the selectcommand inside the sqldatasource I use four-part-name and the IP is hard coded in some aspx files.
I want it to be taken from appsettings property instead.

I am trying to read a normal string from the web.config file. When I try to read a string from the web.config file the application doesnt seem to read it. I set my sqlconnection string in the web.config file. It reads a sqlconnection string but not a normal string.Here is my code:
web.config file:
<applicationSettings>
<MyApplication.Settings>
<setting name="Colour" serializeAs="String">
<value> "Red"</value>
</setting>
</MyApplication.Settings>
</applicationSettings
This is how I try to call the setting:
string strColour = Properties.Settings.Default.Colour;
I am using .net framework 4.0

I've created a web page and it contains some settings value in web.cofig for example images.So i want to give the path of images in Web.Config file and file name in that particular image src. I wanted to read that settings only in aspx page not in codebehind. For example Web.Config: <add key="ImagePath" value=[URL]> and in my aspx page, <img id="ImgHeader" runat="server" src="<%ConfigurationManager.AppSettings["ImagePath"]%>" />

I have an ASP.NET site which uses a 3rd party activeX control. I have to pass a few parameters to the OBJECT tag in the HTML page. If i hardcode these parameters into the HTML everything works.
I would like to place the parameters in my web.config with app settings "key/value" pairs.
My problem is i cannot read the app key setting in the HTML markup to succesfully pass them in as parameters. I can read them fine from server side code behind.
What's the correct way to read these settings in the client side HTML markup ?

I'm trying to use the following command:
Dim xmlFilePath As String = _
System.Configuration.ConfigurationManager.AppSettings("XmlFilePath")
to retrieve the following setting:
<applicationSettings>
<MySolution.WebProject.My.MySettings>
<setting name="XmlFilePath" serializeAs="String">
<value>C:ASP.NETFolderMessageLog</value>
</setting>
</MySolution.WebProject.My.MySettings>
</applicationSettings>
However, xmlFilePath shows up as Nothing after that line of code is run. What's the correct code to get a setting out of the web.config file in an ASP.NET application?
NOTE: Although you can add keys individually to the <appsettings> tag, I'm trying to figure out how to use it with the "Settings" tab in the project's properties.
