Project 31-A

Introduction The project required the need to put the visual pie chart on a web page on the client and in a Pdf file created on the server. I eventually choose to use a Telerik Kendo DataViz Chart control on the client, and use a PNG file on the server for the Pdf file. This blog post will explain the process and code to convert the client-side pie chart Svg data to a Png file, and provide a download to the working code. Prerequisites You need to have a trial version of the Telerik Kendo library installed in order to make the sample code work. You also need InkScape installed. InkScape is the application that does the actual conversion. You will need to change the Web.config appSetting of “ExeDirectoryForInkscape” to represent your own installation location. Any SVG Data Will Work The pie chart was created using the Telerik Kendo DataViz chart control. While I name a specific control, as long as you have access to the SVG data, the same conversion process on the server will...

Introduction Recently, I needed to restyle an HTML <SELECT> box so that the selected element had a different background color. In all other ways, the element could be exactly like an HTML <SELECT>. Below are both the original element, and the restyled element.     This type of style change allows the novice user to immediately identify the control’s implied usage while allowing for some coordination with the site and page’s overall style.   Technology Platform The project is an Asp.net MVC site with jQuery, and Knockout.js on the front-end requesting json content on the backend. For the purposes of this blog post, I’ve stripped down the functionality so that just the required elements are visible. The project was already using Telerik Kendo controls so morphing the Kendo Panel Bar into a <SELECT> element was suggested. The main work is in the css file but the entire working sample project is available for download.   Telerik ...

Introduction Several things happened in a short period of time to influence my decision to take a Ruby/SaaS class. I’m a lifer on .Net or more specifically Asp.Net and it’s precursor, Asp. First, the MVC .Net book I was reading at the time said programmers either use .Net or Ruby for MVC development but not both. Second, an online UC Berkeley class was free and gave me both a new language ( Ruby ) and backfilled any software-as-a-service (SaaS) holes in my knowledge. Third, the class used the Agile methodology which I had bits and pieces of. I wanted to see someone else’s interpretation put into practice.   Ruby on Rails (RoR)/MVC I knew MVC , web protocols, and web development so the learning curve was all Ruby. The class had a quick pace where I knew how to do it in .Net but not Ruby. Ruby, fortunately, is a very easy language to pick up. It feels very much like a script kiddie toy but  more powerful.   Interpreted versus Compiled Ruby is interpreted w...
