Im using code like this :
<li id="x" runat="server" code="myCode"> ...
Is it possible to iterate through each control on the site check if it has got code attribute and if yes process it it any way ?
Im using asp.net 2.0 attempts in castings return null so that I dont have control over attributes
foreach (object control in this.Controls.ToString())
{
HtmlGenericControl gc = control as HtmlGenericControl;
if(gc != null)
{
if(gc.Attributes["code"] != null) ...
the code below doesnt enter into if. All
I am developing web applicaiton. I want to read web.config in App.config file. I have appSettings and connectionStrings in web.config. How to read that?
View 10 RepliesWeb.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 know how to read a stuff from web.config in .cs file, but how can i read something .aspx source? For example i want to do next <a href="somethingFromWeb.config"></a>
View 1 RepliesI need to read configuration elements from the web.config. Let this be my web.config.
<family>
<parents>
<child name="Hello"/>
<child name="World"/>
</parents>
<parents>
<child name="Hello1"/>
<child name="World2"/>
</parents>
</family>
So I have something like this, I need to read this into a collection.
<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 have a xml configuration file like below format.
<setting>
<web>
<mailid>xxxx</mailid>
</web>
<network>
<logid>sd</logid>
</network>
</setting>
i would like to programmatically read entry from xml config file which is same as asp.net webconfig file reading.
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 custom config section for my application. For some reason Visual Studio 2010 isn't picking up and of my custom properties. I'm getting warnings similar to this for all the "add" keys: Could not find schema information for the element 'urlFilterSection'
CONFIG FILE:
<configSections>
<section name="urlFilterSection" type="BotFinderApp.Models.UrlFilterSection, BotFinder" />
</configSections>

I have a couple of configuration files flxConnection.config and flxSecurity.config files which are being referenced from the Machine.config file like below.
<securitySettings configSource="flxSecurity.config" />
<connectionStrings configSource="flxConnection.config" />
I would like to encrypt the files (a) flxSecurity.config and (b) flxConnection.config using the RSAProtectedConfigurationProvider using a custom RSA key, which can be deployed to other servers. How is that possible? If possible, looked at a variety of stuff in the internet and they all seem to be referring to either Web.config or Machine.config encryption which is pretty straight-forward. This is how the flxConnection.config looks like,
<?xml version="1.0"?>
<connectionStrings>
<add name="LocalSqlServer" connectionString="data source=.SQLEXPRESS;Integrated
Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
providerName="System.Data.SqlClient" />
</connectionStrings>
This is how the flxSecurity.config looks like,
<?xml version="1.0" encoding="UTF-8"?>
<securitySettings>
<add key="APC_APP_ID" value="apcrpt"/>
</securitySettings>
I'm getting an ConfigurationErrorsException when trying to load a custom section from my web.config.
I'm trying to register a custom section in web.config to load it later using a "Section Class".
Suppose my section is orderService, and I register it in web.config as shown:
<configuration>
<configSections>
<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
</sectionGroup>
<section name="orderService" type="orderService"/>
</configSections>
<orderService available="true" pollTimeout="00:01:00" location="abc">
</orderService>
<appSettings></appSettings>
<connectionStrings/>
Then I try to load it with:
Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
OrderService custSection = OrderService)config.GetSection("orderService"); <== The exception is thrown here (OrderService is a class that inherits from the class ConfigurationSection, and that defines a property for each orderService property, in this case: available, pollTimeout and location)
The exception says: An error occurred creating the configuration section handler for orderService: Could not load type 'orderService'. (my web.config path line 23) Does anybody know what am I doing wrong here? (I got it from the book APress: Pro ASP.NET 3.5 in C#)
For some reason the Custom Errors for 404 pages are not working on my production server, but they work fine on development. Instead of going to the custom 404.aspx page, it goes to the ugly IIS 404 page.
Here is my Custom Errors protion of my web.config:
[Code]....
I changed the defaultRedirect to also go to my 404.aspx page just to make sure I was catching everything, but still it does't work. I know I could change the IIS 404 error to also point to my 404.aspx page, but that will not work for me because I need to capture the "aspxerrorpath" in the querystring for .net 404 errors. The IIS method will not give me that.
I am just hoping it is a server configuration I missed somewhere, but everything on production looks the same as on development.
If I create a custom error page in my web.config file, how do I retrieve error details in the error page?
So with ...
<customErrors mode="On" defaultRedirect="/error/error.aspx">
<error statusCode="404" redirect="/error/404.aspx" />
</customErrors>
I am referring to errors generated by my asp.net. For example I created a sample page and wrote 'throw new Exception("some error")' as a test. How can I retrieve an instance of the exception or exception details in my "/error/error.aspx" page? Currently in my error page if I query Server.GetLastError() the return value is null.
I am trying out some code which enables me in creating a page with extension .asp2
The tags included will also be custom, something like:
[code]....
I have done the necessary changes so that ASP.NET identifies the extension. I have also kept a mapping of custom tags and asp.net/html tags with myself. With this I am able to render the page on browser. But how can we do event handling(usually done by page postbacks and code) in such a scenario?
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.
I have many Connection strings in my web.config file. I also have a "dataConfiguration" setting in the same file which specifies what database my app connects to.
How do I read the "defaultDatabase" setting / section from the, see below xml file.
<configuration>
<configSections> [code]....
i hae a doubt in my web application i place two network tags in smtp like this...

I have Created a custom CheckboxList as [Code]....
but when i am passing this cutom control another page via parameter to newxt page i am not able get the selected checkbox
I have deploy my web site, it contains a project!
in MyWeb there are all the aspx page and some entites datamodel, in MyApp there are the class with function like "getter data from DB" and there is a entity data model.
afeter the deploy, I have only the web.config and the connection string for the entity datamodel....itīs run ok, read/write the data on the DB.
The problem is with MyApp.....after the deploy it is a dll file and I donīt have the app.config and the entity inside it donīt run, not read/write nothing on the DB.
There arenīt error or messager but not read/write the data in the MyApp project.
all run on the iis 7
now...the question is:
I lose the connection string (in app.config) after the deploy?
Can I put a entity in the MyWeb and read it in another project (myApp)?
ps: for connect to DB I use not the c# code:
var db=from x in AccessDB.Example select x;
how one might go about implementing your own custom tags in JS pages served by ASP.NET?
Basically what I am looking to achieve is a way of creating "includes" for my Javascript files by adding some code such as.
//Include Src="MyJavascriptFileLocation.JS"
And then having the ASP.Net handler serve my javascript file but also dynamically append the referenced javascript file to the location where the include is written.
While using a third party dll I was getting the following exception - "exePath must be specified when not running inside a stand alone exe" with following trace
System.Configuration.ConfigurationManager.OpenExeConfigurationImpl(ConfigurationFileMap fileMap, Boolean isMachine, ConfigurationUserLevel userLevel, String exePath).
The reason I found was that it was looking for app.config and I had provided the details in web.config. My question is why does the system.configuration differentiate between web.config and app.config.
I upgrade my application from .NET 2.0 to .NET 4.0. Everything went smooth, with very few errors. Now the code is compiling fine, but run time environment is loading the configuration parameters from app.config instead of web.config;Here is my setup:Objects project: has app.configUI project: has web.config, When I run this site, it is fetching the configuration parameters from app.config. Any idea if I need to make any changes to read it from web.config instead of app.config? It used to work fine in my previous environment.

Currently in place, I have an outbound rule to convert lowercase URLS to lowercase and to also strip aspx extensions for SEO-friendly URL's...

Works great for all pages linked within my website, but when I'm linking to other websites it still downcases which ends up breaking the URL.
