Wijmo Wednesday: Server Side Grid Magic

In a previous post, we discussed how to add a whole bunch of awesome features to a standard HTML table and transform it into a “grid”.  What I’d like to do today is show you how to move a lot of this functionality over to the server. By harnessing the server to do a lot of the “heavy lifting”, we can give our users a smooth experience.  What heavy lifting would need to be done?  Assume you have a data set of 1 million rows.  That’s a lot of data to send to the client, and then sort/page/filter.  If we ask the server to sort/page/filter the data before sending it to the client, we can quickly reduce the overhead of the client. I’m going to be using the example from my webcast, which you can access here. The Server For data, I’m using the Chinook database.  It’s quick and easy to set up, and gives me good data to use in my examples.  I’m using ASP.NET MVC 3 for my examples, and we’ll only be implementing sorting and filtering. public JsonResult GetAlbumList()

Setting BackGround & ForeGround of WPF FlexGrid rows with CellTemplate

Custom Sorting on C1DataGrid for Silverlight

Sorting and Filtering are very frequently used database operations while working with Grid controls. C1DataGrid for Silverlight supports both of  these  interactive operations.

ComponentOne and CodedUI: Tips and Tricks Part-I

[Press] ComponentOne Releases a Collection of 40+ UI Widgets Powered by HTML5 and jQuery

PITTSBURGH, PA – February 8, 2012 – ComponentOne, a leader in developer-productivity tools, has announced the 2012 release of Wijmo: a kit of UI widgets for HTML5 and jQuery development.  The centerpiece of this release is the stunning data visualization widgets, including more HTML5 chart types and new HTML5 gauges.

Testing Wijmo Gauges in jsFiddle

One of the great advantages to Wijmo is that they are widgets for the extremely popular jQuery UI. This means there is a great deal of support for their underlying library--lots of support means lots of nice things. One of those nice things is the cool jsFiddle,which is a live HTML/CSS/JavaScript snippet editor of sorts.  It's an awesome way to test small things quickly and with no overhead.  We can, in fact, do live testing of Wijmo widgets, and here we'll see how.  Because Wijmo gauges use SVG or VML based on the browser's capabilities, they are a great part of the "plugin-free web" (being promoted for mobile Safari on iOS and Metro IE in Windows 8 ) which is why we can fiddle with them like this.

Charting with Multiple Plot Areas

This can all be achieved using the advanced capabilities of the ComponentOne Chart for XAML.
