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

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.

here i am getting exception,
Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "MessagesResource.resources" was correctly embedded or linked into assembly "App_Web_eerdggo8" at compile time, or that all the satellite assemblies required are loadable and fully signed.

I have two ListBox in my ascx file, I fill them with some data (no problem here), I make them multiple and increase the size, below is my code.
[Code]....
I use some jQuery code to exchange element between them (Here too, no problem). My problem begin when I post my form, I'm unable to get the data from the DropDownList with attribute multiple or size. I tried in my controler to add a FormCollection parameter, I can see every element in my form except those select tag with more options than id and name. I tested to put a manual select tag in my code with only an id and a name then add size and multiple attribute, when there is only id and name I can get the value but when there are more I can't get my select tag in the FormCollection
Also I need to get all the value in the ListBoxand not only the ones who were selected. I have been searching answer for 2 fays now... Without success, I only find resource on how to show ListBoxbut not how to get values from them in mvc web site and I don't find any resources who talk about multiple selection ListBox, I think I'm a bad searcher but....

We are going develop a web application using asp.net. This applicaton is going to server 50 users per day and 40 users concurrently. As the user count is less, we are planning to have two webservers clustered under a webfarm. We are planning to go for a Sticky Session. Netscaler is the load balancing and reverse proxy we are using at hardware level to route to the same webserver till the end of the client session.
1. Do I need to implement any handler at asp.net level to route the session or to provide browser cookie details of session to NetScaler? If so, what should be implemented in detail. Any sample code will also be helpful.
2. I need to maintain a big chunk of object information in session. Does a webserver can handle it?
3. At the hardware level how ReverseProxy works to navigate it to the same webserver? I want conceptual details of it from a web application end.

Is there any way to read configuration section group of IIS7 by using WebConfigurationManager o anything?
I tried to read the authorization section but WebConfigurationManager.GetSection() returns an 'IgnoredSection' instance.
This is what my code looks like...
authSection = WebConfigurationManager.GetSection("system.webServer/security/authorization", HttpContext.Current.Request.Path)
