.net - New Asp "showat" Attribute Required Inconsistently In VS2010. Why
Apr 1, 2010
When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile:
Control "ddState" is missing required attribute "showat".
I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following:
solves the problem. Why do I have to add this to generated code but not other times?(It's a VS-2010 webforms project, using VB, in case that makes a difference.)
I am migrating from IIS6 to IIS7, and IIS6 was fine with this. I already made one change (system.web to system.webServer) and I don't know what's wrong with it now.
We're trying to get a conditional attribute to work, case in point, there's a boolean (checkbox) that if checked, its related text is required. So, ideally we'd have something like ...
public bool Provision { get; set; }
[ConditionalRequirement(IsNeededWhenTrue = Provision)] public string ProvisionText { get; set; }
Is this even possible?
Alternate idea (not as elegant?) public bool Provision2 { get; set; } [PropertyRequired(RequiredBooleanPropertyName = "Provision2")] public string Provision2Text { get; set; }
I'm having a problem with a multilanguage application in MVC. On my model I'm using the following:
[Code]....
This takes care of validation... However the messages are always in the default language. Meaning that the setting of the culture of my thread is occuring too late (I'm currently setting it in my base controller 'OnActionExecuting'). Where could I patch in to change the culture accordingly before validation takes place?
i am trying to create a datatable entering the columns that i create before, but i have a problem, the dataColumn doesn't have the required data, there is a AllowDbNull but it doesn't work.
Then i would like to add other restrctions like MinLegth.
when i execute the above code,i observed that in status bar message as "connecting to localhost",if they are client side controls what is the need of going to local server,why it is happening?
I created a simple Master Page in Visual Studio 2008:
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
and got green underlined 'Master' with two warning messages: 1.Validation (ASP.NET): This attribute name must be followed byan equal (=) sign and a value. If the value is in quotation marks, the quotation marks must match. 2. Validation (ASP.NET): Attribute 'Master' is not a valid attribute of element 'Control'.How I can get rid of the messages?
i'm trying to host an .net framework4.0 application in IIS7. i got an error while clicking on the manage module in modules .like ("Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. ") .I changed my application poll to .net4.0.I am able to browse my application
I installed Microsoft Visual Studio 2010 Ultimate Trial and converted existing asp.net 2.0 web application and I am getting this error: znrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. It's coming from this section in the web.config which was auto-generated by VS2010 when I converted the project:
I am developing asp.net mobile application. I am using LINQ to XML to query XML file. I am using the following query to retrieve the name & value of the query dynamically as follows
var TotalManifolds = from MF in FieldRoot.Element("FIELD-DEFINITION").Element("MANIFOLDS").Elements("MANIFOLD") join SLT in FieldRoot.Element("FIELD-DEFINITION").Element("SLOTS").Elements("SLOT") on (string)MF.Attribute("MID") equals (string)SLT.Attribute("PARENT") select new { SlotName = (string)SLT.Attribute("NAME").Value, SlotValue = (string)SLT.Attribute("NAME").Value };
In the following statement of above query I want to retrive the name of the attribure dynamically without explicitly specifying the name of the attribute SlotName = (string)SLT.Attribute("NAME").Value Here I am explicitly specifying the name. I want to code which can dynamically retrieve the name of the attribute. I am new to Linq to xml. how this can be done programatically? or can you provide me the link through which I can resolve the above issue ?
I am trying to achieve a SSO implimentation across my websites so i am using the machine key attribute to do so.now the trouble starts here as the website the user logs in is on the .net 1.1 framework and the website it it navigating to is .net 4.0.I have share the same machine-key across both the application . It works fine in my testing environment but as i move to the deployment server ,it just dosent work !So what i could do is read this article on MSDN :
http://msdn.microsoft.com/en-us/library/eb0zx8fc.aspx this tells me to add a domin attribute like below <forms loginUrl="~Login.aspx" defaultUrl="Default.aspx" protection="All" timeout="80" name=".ASPXAuth" domain="asbc.com"/> but this thing just dosent work on the 1.1 application and throws an error Unrecognized attribute 'domain'.
Where do i get to mention the domin in my 1.1 application.?

Are there any tutorials on how to use FBA within VS2010 and .NET 4.0? When I build a new web app, FBA is already set up but not configured. I'd like to use SQL server for the source.
I was walking through the tutorials on this site but I'm getting confused because some things are already in place.
our company just upgraded to VS2010, but we have not upgraded to .NET 3.5 or 4.0 yet, we're unfortunately still using 2.0. I have the toolkit for 2.0 that I was using with VS2008, but now that I am using VS2010, my AJAX items no longer work. I was wondering first of all if it's even possible to use the old 2.0 toolkit with VS2010, and if so, is there something special I need to do to get the controls to work now that I have opened my project in VS2010?
Both VS200 and IIS are in my local machine. Suppose they have the same permission. I create a silverlight4 w/ wcf ria service project. The project runs well in VS2010 built-in ASP.Net development server. It doesn't work well after i publish it to IIS. I only can see its static content but not the .svc. i try to browse the .svc, it always show HTTP 500 error. I doubt if i do not open the asp.net runtime setting sth in IIS?
I am working on a large website that is comprised of multiple applications. We are still using web forms. All of the applications are in a common directory that serves as the root directory in my localhost. The site was originally built in 2005 on 3.5 but has been migrated to 2010 still running on 3.5 (2.0). My problem is that my debugger will run once. After I stop debugging I cannot run the debugger again - it just hangs. My locals and watch windows open but do not populate and the browser never opens. We are running Visual Studio 2010 Ultimate on Windows 7 32 bit.
Visual Studio 2010 hangs up more tha 20 times in a working day. I'm thinking of going back to 2008 but that is such a hassle. Mostly it hangs when debugging starts and when I open a xaml file. I'm doing silverlight/WCF development.I have HP I7 laptop, 8gig, windows 7 64bit.
I need little advice from you who has experiences in EF4 and IBatis. I would like to upgrade my applications that used IBatis technology and VS2005 to VS2010. The reasons of upgrading are i would like to use the latest technology and also enhance my applications with features that not provided in .Net 2.0
I already try EF4 in VS2010. It looks like nice feature to create application but i need more information about it advantage and disadvantage in performance,security,stability etc. As information, i was using generator to wrap IBatis.Net and VS2005, so it seem the .edmx file similar with classes that my generator was created
I just discovered that a (simple) website I'm working on will be deployed to a server running framework 2.0. My quandry is that I started it using VS2010 and framework 4.0.
Is the solution as simple as changing the compile to options? I'm assuming that I'll have to remove the Listview controls I am using as they didn't get introduced until 3.5 (i think).
Am I basically correct with this or am I missing something?
I have a web application I want to deploy via Web Deploy, using "Build Deployment Package"
It has a folder called "Errors". This is part of the project. Web Deploy adds it, but how do I specify that i want the application to have Write permissions on this folder?
Do I have to manually edit the source manifest each time, or can I set it somewhere to get the package to do it automagically?
I've been though this once before, but somehow can't get these two items to run correctly (VS2010 - Server 2008 R2 - .NET4.0) WC3 Validation I have entered (in Web.config)
[Code]....
and the favicon is displayed in the browser tab when run locally, but not when published.
I would like to include a word document, and unused program files in a folder as part of my project, but I don't want it compiled, etc. How is the best way to do this?
