The name 'ViewData' does not exist in the current context

-
Good Evening!

In an application where I played the class diagram in visual studio by adding controller class, repository class, and service class, I encountered an error "The name 'ViewData' does not exist in the current context" in my HomeController.

This is weird since the controller references System.Web.Mvc. The solution is:

1. Copy the source code in the HomeController and transfer it in a textfile for backup.
2. Delete the original HomeController.
3. Add another HomeController class
4. paste the backup code from the textfile.

I guess this is a bug when using class diagrams in Visual Studio 2010.

Good day to all! Here's an example of a WPF CRUD (Create,Update and Delete) project using the DataGrid control, ADO.NET Entity Framework 6.x, C#.NET and Model–View–Viewmodel(MVVM) architectural pattern.

The steps below are pretty straightforward and easy to follow. I. Project Setup 1. Add a table called Students in you database. The complete script is found in this post WPF CRUD With DataGrid, Entity Framework And C#.NET 2. Create a WPF Project and add four folders called DataAccess, Model, View and ViewModel. 3.

Good Day Gents! During this free-time I started setting up Node.js on my machine as part of my career goals which is learning new frameworks in preparation for new projects. So the first thing I did was to install TypeScript language to get myself familiar with Angular 2+. After I finished setting up TypeScript, I then created a simple HelloWorld program and ran the application through Visual Studio Code using the "tsc: build - tsconfig.json" command. I encountered an error which says "The term 'tsc' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again." Below are the details on my machine and packages installed:   - Operating System: Windows 10 Pro   - Node.js: 14.16.0   - npm version: 6.14.11   - Typescript: 4.2.3 (using command: "npm install -g typescript") After doing some research and reading th...

Invalid nested tag div found, expected closing tag input

-
Hello all, I've been experimenting on how to print html document using the said 3rd party software called iTextSharp . iTextSharp is a popular tool and has several examples on the internet regarding integration to the project and occurring issues. One of the issue I encountered is Invalid nested div tag and is expecting a closing tag input . As I trace back my html source, the tags are well-formed except that they are self closing tags such as <input>, <hr>, <img>, <br> or the like. These tags when passed to an action method as string are not properly closed and thus an issue is thrown by iTextSharp's XMLWorkerHelper's ParseXHtml() method. <img src= "~/Images/success.png" /> <input type= "hidden" name= "OrderStatusHTML" /> <input type= "submit" id= "btnSubmit" value= "Export to PDF" class= "btn btn-success" /> The solution I came up with is to fi...
