Client side validation is pretty handy. However, as we all know, you can’t fully trust any data sent to your server from a web client. As such, we generally duplicate validation in both the client and server side scenarios. This isn’t a big problem, but it does create a disconnect when the client validation passes, but then the server validation fails. Even in duplication, I still want server-side validation to play an integral part of the overall user experience.

WebAPI Authorization in Views and Unit Tests
posted on September 28, 2015 by long2know in ASP.NET, MVC, WebApi
In my .NET 4.5 MVC projects, I already have helper methods/extensions that let me determine if a user has access to a particular controller action. This provides a nice mechanism to hide and show buttons, hyperlinks, or other UI action elements based on the authorization attributes that have been defined on the MVC Controller.
However, this is a bit more complicated with ApiControllers.
Developing and Deploying .NET Applications on Linux (Part 1)
posted on September 7, 2015 by long2know in ASP.NET, Microsoft
As a web developer primarily utilizing .NET for backend server development, and as one who uses Linux for my own hosting environments, Microsoft’s efforts to make .NET 5 cross platform are welcome. Over the Labor Day weekend, I spent a bit of time seeing how I could leverage this to host .NET web applications myself. While I mention Mint Linux, specifically, this guide should apply to any Debian/Ubuntu derivatives.
IE11 rounded-corner bug
posted on September 4, 2015 by long2know in css, Web
Last month, I made a blog post detailing how to use CSS arrows as a progress indicator. I really like this and use it whenever I’m asked to create a wizard-like interface.
However, I discovered, after finally updating from IE9 to IE11 that there is a specific IE11 bug that reared its ugly head.
JavaScript and Web sandboxes
posted on August 10, 2015 by long2know in JavaScript, Web
In case you hadn’t noticed, I use JsFiddle for most of JavaScript demos and to embed samples into my blog. I like JsFiddle, but it does have a few annoyances.
As a result, I started looking at some alternates.
Visual Studio Code
posted on August 10, 2015 by long2know in Microsoft
Over the weekend, I started moving various source files over to github. Typically, I just use Notepad2 for basic editing and such.
However, after all the good things I read, and have seen, about Visual Studio Code, I finally decided to give it a try as a basic editor.
Flexible layouts to the rescue (again)
posted on August 5, 2015 by long2know in css, Web
Currently, I’m working on a web project that has searchable tables. The layout requires that the search results that is displayed in the table is scrollable. The idea behind this is such that controls to perform search, paging, and other functions on the table are always in view. There are buttons above and below the table.
If you recall my previous post about CSS flex-box, you saw how you can cause elements to grow/shrink as the browser viewport changes. This seemed like an appropriate technique to achieve what is essentially a vertical fluid-layout.
CSS Arrows for Wizard Progress
posted on July 24, 2015 by long2know in css
Making arrow blocks in CSS is pretty easy. You can manipulate the borders of elements, create outlines with overlapping arrows, and other neat things.
One place where I’ve used this is for letting a user visually step through the process of a guided wizard.
Creating, for example, an arrow pointing to the left, we could use a DIV element like so:
AngularJS Date before and after validation
posted on July 23, 2015 by long2know in angularjs, JavaScript, Web
In most of the UI’s I work on lately, it’s necessary to provide start and end date selection. The typical use case is for setting date ranges for searching and storage of effective dates.
Being that these are typically Angular applications, tying into Angular’s form validation makes a lot of sense.
Angular multiselect dropdown
posted on July 21, 2015 by long2know in angular, JavaScript, jsfiddle
Mutliselect drop-downs are somewhat of a pain. It’s always nice when things are simple and discrete. But, the world is not simple and discrete. Life isn’t simple and discrete.
I find myself many times in need of a good, general purpose multiselect dropdown with checkboxes. There are many options for multiselect, like select2, but for some reason having discrete checkboxes is generally overlooked. This is where rolling my own came into play.
