I am looking to write a few helpers in my own assembly modeled after the helpers in System.web.mvc. My problem is that I cannot use the call to Tagbuilder.ToMvcHtlString since it is internal. So if I return a string it wont be ready for asp.net 4 when it comes.
I don't want to add anything to system.web.mvc as that is a given dll.
what is the difference in C# between the access modifiers internal and protected internal?
View 4 RepliesI am updating some code from MVC 3 Beta to MVC 3 RC.
TagBuilder is unrecognized. Did the way helpers are created changed?
If not where is the TagBuilder class?
And where can I find MVC 3 Source Code?
was tagbuilder dropped in favour of Razor syntax?
If not, where did it go? It used to live in System.Web.Mvc -- not anymore.
When upgrading to mvc2 i noticed some of my javascript that was keying on "Points[0]_Id" (this is invalid for an html id btw) started to fail. I pulled up the source and noticed that the TagBuilder class now generates valid client id's and replaces all invalid characters with the "IdAttributeDotReplacement" (which is a terrible name now, since it's not just a dot replacement character anymore). I started to look for a way to generate client id's using a helper built into mvc and came across HtmlHelper.GenerateIdFromName, but this still generates ids the invalid way!
TagBuilder.GenerateId( "Points[0].Id" ) = "Points_0__Id"
HtmlHelper.GenerateFromName( "Points[0].Id" ) = "Points[0]_Id"
IMO: the tagbuilder class or the GenerateFromName code should not be duplicated in two different spots or else you will get errors like this. Also I consider this change made to TagBuilder.GenerateId to be a breaking change and should be included in the breaking changes section of the release notes.
I know this is kind of obsessive, but is there a way to control the order that the TagBuilder class renders the attributes of an HTML tag when you call ToString()?
i.e. so that
var tb = new TagBuilder("meta");
tb.Attributes.Add("http-equiv", "Content-Type");
tb.Attributes.Add("content", "text/html; charset=utf-8");
tb.ToString(TagRenderMode.SelfClosing)
will return
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
not
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
Changing the order that you add the attributes doesn't change it, it seems to be rendering in alphabetical order
I have a website with auctions and i want to notify the winner. In a forum on my website users have an inbox and i want to send the message to there if they are the winner. Is there a way to message internally?
View 1 RepliesCode:
public static void Test()
{
try
{
OpenConnectionToDatabase(); //Opens a connection to Oracle DB
} catch(Exception e)
{
e.Data.Add("Query:", command.CommandText);
throw e;
}
}
When this code is executed when the Database server is being shutdown and the communication is disrupted, .NET throws the following error: Item has already been added. Key in dictionary: 'Query:' Key being added: 'Query:' at System.Collections.ListDictionaryInternal.Add(Object key, Object value) How can this be?
What is internal access modifier? Where we are using the keyword? How should we use in our application?
View 3 RepliesI have designed an application and am wondering if this is the best architecture to use and whether there is any danger.
In namespace Membership I have a public class, MembershipManager, which inherits from webservice
public class MembershipManager() : System.Web.Services.Webservice
The single public web method of this class often needs to read and write to a database.
[WebMethod()] public string DoMembershipWork(...various parameters...)
The database work is done by implementing, in the same namespace,an internal class
internal class MembershipDataAccess
which has a series of internal static methods for data access e.g.
internal static bool UpdateMembership(MembershipManager m)
The MembershipManager class accesses the data access class by calling the appropriate method with itself as a parameter e.g.
MembershipDataAccess.UpdateMembership(this);
Is this a good idea. This application will be processing many transactions simultaneously. Is there a danger of not being thread safe. Note also that sometimes the MembershipDataAccess class will return datasets to the MembershipManager class.
I created a Website and i upload it using the asp.net development server.
So on the explorer the address is something like this http://localhost:port
The problem is that i can't access the Website(while its uploaded) using my internal IP from within the network.
So if i type http://10.0.0.180:port i get an error "Internet explorer cannot display the webpage".
I disabled my firewall(windows 7).
I do have another PC on the intranet and am not able to access the website using my internal IP address.
View 1 Replieswe have a INTRANET website that was just created.
The problem is the address is 10.110.96.230:8888
I want it to be easy to access. Something like [URL]
This way I can tell my employees to go to [URL] while on the Intranet.
This would be easier for them to access then remembering the IP address.
I did lot of R & D to implement website internal search in asp.net.
I have found a good article in code project
[URL]
It has some limitations
Search with special characters is not working.
Pdf and word documents are not searching.
Not able to high light the searched text.
If I am implementing this in master page then child title is not displayed in result page.
Requirement:
I need to implement search result should be like this [URL] In description the search text must be highlighted.
Note: I need to implement this with coding not any 3rd party tool (I know lots of 3rd party website which do free hosting but they will post there adds and logo). Moreover i dont want to use any database for this internal searching.
Iam working on internal Website search as user can search any thing in the website
Now i dont have idea from where i can get start ?? how search will work .it should be whole database search or pages only???
Im using Google Analytics Dashboard Control which are available at [URL] Issue is its working fine when im connected to internet but if im using it on a machine that doesnt have internet access then it shows Server Error in '/' Application.

Im calling these dashboard control on my View in an iframe like this <iframe src="../../GoogleAnalytics/Visitor.aspx" height="275"></iframe> and if i place try catch in Visitor.aspx page it doesnot catch the exception. How should i catch this exception, Im using asp.net mvc 2 with c#
View 3 RepliesMy company has several web applications written in ASP.NET. We need to make these applications available to Intranet users as well as authenticated external users. Most of the features are the same for the two groups, though there are some extra features available to the Internal users. The two different sets of users would use a slightly different security setup... our internal people will be authenticated using LDAP against Exchange, whereas the external users will have accounts in SQL Server.
What is the best approach for deploying our web apps? Should we deploy 2 copies to different servers, one configured for an Intranet and one for outside users? Or is there a better way to share the code between the 2 servers, yet have the flexibility to use different web.config settings for security??
I have a heavy traffic aspx page calling a web service upon every user`s request as follows.
string uri = "Path.asmx";
string soap = "soap xml string";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Headers.Add("SOAPAction", ""http://xxxxxx"");
request.ContentType = "text/xml;charset="utf-8"";
request.Accept = "text/xml";
request.Method = "POST";
using (Stream stm = request.GetRequestStream())
{
using (StreamWriter stmw = new StreamWriter(stm))
{
stmw.Write(soap);
}
}
WebResponse response = request.GetResponse();
response.close();
Everything is working fine but sometimes I am getting the following error. The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse() Does anybody have any idea about this error or can anybody tell me if I am doing wrong.
I have a web application runs @ Windows 2008 R2, ASP.NET v4.0.
I installed the Url Rewrite Module, and started to use it as shown in the official examples.
My problem starts when the <rewrite> tag is added to the web.config under <system.webServer> - actually when I try to browse to any page under this current application, I get 500 - Internal server error.This is the <rewrite> block I've been adding:
<system.webServer>
<rewrite>
<rules> [code]....
I have a long alphabetical list to be displayed by a gridview.
I need to have links at the top of the page that will link to anchors in the gridview. How can I get anchor tags in the gridview so that the links will jump to them when clicked?
Note: Paging is not an option
I first time tying deploy ASP.NET MVC3 Web App and after upload files and made database I had problems with diplaying sites...I was redirected to "page not found'. After add to web config I get following error:

If I open a connection and don't close it after query execution completes, store it somewhere, and use it next time a request comes in, isn't it something similar to what .net does? Is it possible to maintain a pool of connections according to our requirements without depending on ADO.NET's internal mechanism? In case of ODBC, I read somewhere that connection pooling will have to be enabled from ODBC datasources and that it cannot be set from within .net. What if I open a few ODB connections, leave them open and
use those whenever a request comes in and close all of them when I know that I dont need them anymore. How is it different from connection pooling?

I'm working on a custom control that can contain some javascript, and read this out of the page into a string field.
This is a workaround for dynamic javascript inside an updatepanel.
At the moment, I've got it working, but if I try to put a server tag inside the block:
<custom:control ID="Custom" runat="server">
<%= ControlName.ClientID %>
</custom:control>
The compiler does not like it. I know these are generated at runtime, and so might not be compatible with what I'm doing, how I can get that working?
EDIT
Error message is: Code blocks are not supported in this context
