Recommendation For .NET Webforms Validation Framework?
Mar 4, 2010
I have worked with the .MVC framework using validation frameworks such as xVal or FluentValidation.
Is there anything similar available for webforms as well? I have got a few projects which have to be done using webforms.
What I'm asking for is some kind of integration with the webforms infrastructure. I could just use one of the mentioned frameworks in order to validate the (view/page)models, but I still would have to do a lot of form validation in the page.
I have been looking at learning dependency injections (i think i have now grasped the basics) and am looking to implement it into a webform application. My question is, what dependency injection framework should i use for a webforms project, or is it a question of what works best for you?
I Have currently looked at Spring.Net, Ninject, Unity and StructureMap, i tend to have no preference in the configuration, whether its XML or fluent interfaces. However is XML configuration becoming less favourable?
Most of the information i come across relates to dependency injection whilst in a MVC environment. And have also read that some frameworks such as Structure Map only work with webforms using version 2.0 or earlier. So the kind of things i need to consider are whether webforms will be continuous support, and the ease of configuration for someone relatively new to the pattern.
I am sort of new to Entities Framework however I have successfully built a complete CMS website with the Entities Framework 4.0 in MVC 2.0 following the design patterns and examples laid out in nerddinner and MusicStore.
I am now building another application in ASP.NET webforms however would still like to flex the ORM capabilities of ADO.Net Entity Framework 4.0 however found that it seems like I am always forced to use Entity ObjectDataSource to bind to a GridView etc...
I know I might sound silly to some however I need a few pointers on creating this ASP.NET web application to use Entity Framework and use something like the design pattern of Dependency Injection etc... and still able to bind to GridViews programmatically in code behind.
I like the seperation of using a ntiers design but also would like to have full code control and not be forced to use ObjectDataSources in my aspx page.
I'm using ASP.NET MVC 2, DataAnnotation and MicrosoftMvcValidation.js for validation. I have two forms in my view..is there a way to use validation summary like in ASP.NET Webforms.
I am using ajax.beginform. i am inserting and updating records using ajax and showing the inserted or updated value in the div above the div containing form. I need to apply validtion on these values.what is the recomended validation framework for this scenario. i have problems pushing validation messages to the form as i can only update one div that is indicated in updatetargetid parameter of ajax.beginform and this value in my case is set to div displaying the updated/inserted data
how to use jquery in an asp.net nested masterpage. I have my main masterpage where I have added the link to the jquery libaray and also the validation framework. I have then created another masterpage with some styling and created a aspx page based on that masterpage.How can I attach the validation framework to textboxes within my page?
I am looking for an open source, Windows, .NET based, CMS. I have a few simple requirements:Must run in or be built on the .NET 4 framework Users must be able to automatically authenticate via IIS / integrated windows authentication Must be able to utilize custom pre-built (existing) user controls presented as widgets / web parts / etc. with a minimum of re-coding.I have looked through a handful of open source CMS projects with no luck so far. If anyone knows of a CMS that fits the bill I would really appreciate your insights.
I need to implement a centralized form validation framework for my ASP.NET(C#) 3.5 website.
And for this I have tried the following solutions-
[URL] [URL]
I have added the .dll file in my project's BIN folder and for Matt Gibb's solution I have also added the tagMapping code to web.config file. But for both of the solution, when I ran the project I noticed it doesn't have any effect on the validation controls.
I know this question has been asked million times but I think my situation is different here.I am using .NET Framework 3.5 SP1, there is no form action on the page and it's not happening when I try to submit the form quickly. I am not on a web farm either.I have a page with two GridViews. One Gridview acts as a master gridview and second as detail gridview. First Gridview has autogenerate select button and clicking select would bring related records in detail gridview at the bottom. I have a refresh Link button at the top. Everything works fine. I click refresh button and it works fine too.Ok when problem start happening when I leave the page idle for like 10 minutes or so and then I click Refresh button only then I get this "Validation of Viewstate MAC failed" error.
I have a form that I have been getting submissions that have punctuation and special characters that trigger the potentially dangerous Request.Form value error. I have been trying use the httpUtility.htmlencode and Server.htmlencode method to sanitize textboxes and textareas.All my tests do not fire because the built-in request validation of the 4.0 framework prevents the code-behind from executing to perform the sanitization. I have included the ValidateRequest in the page header but no matter what I set it too it still does the same thing.
Im a newbie working on my first ASP.NET webpage using Visual Studio 2010. Im looking for a recomandation on a flexible webpage navigation/menu system. I need a dynamic system that uses SQL as backend (so that webmaster can update menus/navigation using a simple CMS) Any good systems out there you would recomend?
Over the past 3 years I have been using (...shamefully) SharePoint 2007, DNN and Tridion to develop web portals. I am however looking to move off SharePoint and Tridion (lack of control over urls, markup and tdd) and am looking for alternatives.
Which of these would your vote go to and why? Could you share any experiences you have with these:
Orchard Sitefinity Umbraco N2
Although Orchard and Sitefinity seem easily extensible, I am worried about community support.
I have questions relating to specifying font-sizes in web page.Is it ok to specify it as style='font-size:12px' or style = 'font-size:14pt' or there is a better way to do this? I want to be sure that I get a uniform cross-browser solution to font-sizes.
I'm using DotNetOpenAuth as my membership system, and the way I have it working now seems to be working quite well. What I'd like to do however is build into my website the ability to check user credentials against the AuthCookie rather than a session. In the membership provider, I can check for the username like this
string UserName = System.Web.HttpContext.Current.User.Identity.Name; ''# which returns the OpenId ClaimedIdentifier
What I'm wondering is if there is a way to extend this so that I can retrieve custom properties from the AuthCookie rather than having to create my own session object. Currently I have this setup.
UserSessionModal Namespace Domain Public Class UserSessionModel Public Property ID As Integer Public Property RegionID As Integer Public Property Username As String Public Property Slug As String Public Sub New(ByVal user As User) _ID = user.ID _RegionID = user.RegionID _Username = user.UserName _Slug = Replace(user.UserName, " ", "-") End Sub End Class End Namespace
BaseController (inherited by all controllers) Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker ''# Create a UserInfo object for the logged in user ''# and store it in a session state. If Session("UserInfo") Is Nothing AndAlso User.Identity.IsAuthenticated Then Dim user As Domain.UserSessionModel = New Domain.UserSessionModel(OpenIdService.GetOpenId(HttpContext.User.Identity.Name).User) Session("UserInfo") = user End If Return MyBase.CreateActionInvoker() End Function
Then in my views I do something like this
<% Dim user As MyApp.Core.Domain.UserSessionModel = DirectCast(Session("UserInfo"), MyApp.Core.Domain.UserSessionModel) %> <%: Html.ActionLink(user.UserName, "Details", "Users", New With {.id = user.ID, .slug = user.Slug}, Nothing)%>
What I really need to be able to do is remove the Session stuff all together and just simply check the AuthCookie for my custom properties ID, RegionID, Username, and Slug. I can already get the "ClaimedIdentifier" out of the AuthCookie using HttpContext.User.Identity.Name... I just need to be able to extend it.
We have an application that may or may not have problems during heavy load. To try to get more correct usage patterns regarding load, we'd like to just fire up a bunch of users logging in, and then repeatedly just navigating through a list of links (our menu basically.)Is there any open source or free tools we can use? We're not adverse to pay for anything if we need to but right now we are trying a bunch of different things and we'd like to hold off on this until we know a bit more.Of course, some simply Python scripts would do the trick, but if there's anything we could input our links to that saves us a bit of time in this it would be most welcome.

I host a website that has recently been upgraded from .NET Framework 2.0 to .NET Framework 4.0. Within the website, I have an instance of BlogEngine which still requires .NET Framework 2.0. Each website is in it's own application pool. My issue is that when I browse to the blog portion of my website, I receive a 500.19 error with the following information...
The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration The web.conf file that is listed in the error message is the config file that belongs to my root website which is running .NET Framework 4.0. How do I get the two websites to run together in the same website using different versions of the .NET Framework?
I have this cenario:One server (machine) that have framework 3.5. And one site (website) developed for framework 3.5.This site can not be modified (rebuild in other FW version, or others changes).

As I know, the new webaplication work in the server, if I install framework 4.0 in the server.
My question is: Can I install the framework 4.0 on the machine that already have framework 3.5. And continue have sites working with other frameworks version?Or, should I develop my new webapplication in framawork 3.5 ?If I can install the framework 4.0, do I need make some specify configuration during the installation?
We are developping with .net framework 2.0 on our dev station and we deploy on web server and client desktop a 3 tiers smart client app. what is the impact of ugrading to .net framework 2.0 sp2 on our web servers WITHOUT upgrading on dev station and compilation servers?
I have an old Web application which is using net framework 2.0(build with vs2005), now i need to move the old Web application to production server which has .net framwork 3.5 installed. Do I need recompile the web application with vs2008 or i can just go head move the the Web application without recompiling, it will automatically work?
