In the event that you'll be referencing Castle Windsor 3.3.0 and incorporate the IOC container in your project, you will encounter the error stated by the title of this post. This happens when you use register the controllers to the IOC container using AllTypes class. 1 2 3 4 container.Register(AllTypes.FromThisAssembly() .Pick().If(t => t.Name.EndsWith( "Controller" )) .Configure(configurer => configurer.Named(configurer.Implementation.Name)) .LifestylePerWebRequest()); This class has been deprecated in the recent versions of Castle Windsor. The solution is to update the Register method and replace AllTypes with Castle.MicroKernel.Registration.Classes . 1 2 3 4 container.Register(Classes.FromThisAssembly() .Pick().If(t=> t.Name.EndsWith( "Controller" )) .Configure(configurer => configurer.Named(configurer.Implementation.Name)) .LifestylePerWebRequest());

Hello, Here's a VB.NET example on how to perform form validation using jQuery and Bootstrap without Model class. Validation is performed purely on the client side. The steps are explained in detail at VBForums codebank ASP.NET MVC 5 Form Validation using jQuery and Bootstrap without Model class and the source code can be downloaded in github MVCFormValidationJQueryValidateVB . Screenshots: That's it.. :-)

I have an external JavaScript file that validates a form using form.validate() of jQuery validation plugin. $( function () { $( "#frmInput" ).validate({ submitHandler: function (form) { //submit once validation rules are met form.submit(); }, .....other codes here }); }); When integrating it in an MVC 5 application, the validate event does not trigger. I have checked if there are errors using the Chrome developer tools and Firefox but to no avail there is none. The solution I discovered was to change the BundleConfig.cs file and the order of scripts rendering in _Layout.cshtml. After that, form validation now works. Steps: 1. Change BundleConfig.cs codes //change code in BundleConfig.cs From:   bundles.Add( new ScriptBundle( "~/bundles/jqueryval" ) .Include( "~/Scripts/jquery.validate*" ));   //To: (individual bundling of validate and unobtrusive js files)   bundles....

As I was converting a registration form from MVC 5 C# website to VB.NET MVC 5, I've noticed that in VB.NET the div elements with form-group class have different spacing in between compared with the former project. I've doubled checked and compared Site.css and my custom css files and all styles are the same. Luckily, I found out that MVC 5 VB.NET project includes the older version of Bootstrap that is version 3.0. So, replacing the old bootstrap files in VB.NET project with bootstrap.min.css and bootstrap.css version 3.3.6 corrected the issue.

When integrating jQuery validation in ASP.NET MVC, here's how to apply client-side remote validation using javascript code. Below are the snippets and screenshots. Make sure to render the jquery.validate.min.js file in your View or Layout. Email HTML Markup: 1 2 3 4 5 6 7 <div class= "form-group has-feedback" > <label for= "email" class= "control-label col-md-3" >Email Address:</label> <div class= "col-md-9" > <input type= "email" name= "email" id= "email" class= "form-control" placeholder= "Enter email" /> <span class= "glyphicon form-control-feedback" id= "email1" ></span> </div> </div> Custom Javascript Validation Code: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 $( function () { $( "#frmInput" ).validate({ sub...

Hello, I've created an ASP.NET MVC website that loads a partial view with a WebGrid control on ajax call. When I tested navigating to next record set, the WebGrid performs a postback and then redirects to a blank page. Not only that, the WebGrid control also lost it's css style. After doing some research on it's properties, I basically encountered a property called ajaxUpdateContainerId . After including that property in the WebGrid control, the pagination works fine and does not redirect to a blank page. Original Code: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 @{ var grid = new WebGrid( canPage: true, canSort: true, rowsPerPage: 10); grid.Bind(Model.AddressList, rowCount: Model.AddressList.ToList().Count); grid.Pager(WebGridPagerModes.NextPrevious); @grid.GetHtml(tableStyle: "webGrid", htmlAttributes: new { id = "grid" }, headerStyle: "hea...

Given the following sql statement below using In operator with subquery as it's argument, I need to convert this to LINQ statement. SELECT [CountryRegionCode] ,[Name] ,[ModifiedDate] FROM [AdventureWorks2012].[Person].[CountryRegion] where CountryRegionCode in ( select distinct [CountryRegionCode] from [AdventureWorks2012].[Person].StateProvince) After doing some readings on LINQ documentation, I found it's equivalent LINQ code using let . model.CountryRegionsList = ( from country in _context.CountryRegions let subQuery = ( from stateprovince in _context.StateProvinces select stateprovince.CountryRegionCode). Distinct () where subQuery. Contains (country.CountryRegionCode) select country).ToList();

There was a question in a forum if how can we trigger an onchange event of a DropDownList control inside a GridView template field. This time using unobtrusive approach. So in order to understand a bit further, the GridView control when rendered to the browser becomes a table element while DropDownList becomes a Select control. So, to trigger the event we need to traverse the GridView control then find the Select control and attach a change event. Here's a solution using jQuery. HTML Markup: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 <asp:GridView ID= "gvItem" runat= "server" AutoGenerateColumns= "False" > <Columns> <asp:BoundField DataField= "ID" HeaderText= "ID" /> <asp:BoundField DataField= "ProductName" HeaderText= "ProductName" /> <asp:TemplateField HeaderText= "Time Slot" > ...

Here's a simple client side validation in ASP.NET MVC 5. By default, the application's unobtrusive validation has been set to true in web.config file. For this demo, I did not include a saving process to database. I just added a simple view to indicate a success if the model passed to the controller is valid. See files and screenshots below: Registration.cs (This should be created inside the Model folder) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 public class Registration { [Required(ErrorMessage = "You must provide your first name")] [Display(Name = "First Name")] public string FirstName { get ; set ; } [Required(ErrorMessage = "You must provide your last name")] [Display(Name = "Last Name")] public string LastName { get ; set ; } [Required(ErrorMessage = "You must provide your middle name")] ...
