The ability to show connecting lines between parent-child node is pretty useful and definitely gives a better representation in case of large data. TreeView controls over some platforms have ShowLines property which user can set to see the connecting lines automatically.
Wijmo Gridview does not have any keyboard events but sometimes, we may have a requirement where we need to perform any action on the basis of the key pressed by the end user. In this blog, we will see how we can fulfill the above requirement and can handle the key events of Wijmo Gridview.

Many times our customers have reported issues wherein they are trying to install pre-VS2008 version of ComponentOne Studio Installer but the installation fails with following error :
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()
Usage of a TextBlock is quite common in CellTemplates of Columns in a C1Flexgrid for WPF. There might a requirement of changing BackGround/ForeGround of C1FlexGrid rows on some event, say MouseHover.
Sorting and Filtering are very frequently used database operations while working with Grid controls. C1DataGrid for Silverlight supports both of these interactive operations. However, none of its operations are performed at Grid level. Both Sorting and Filerting are done at DataSource. C1DataGrid does not have any internal logic for these operations.
One of the most popular features that MS came out with in Visual Studio 2010 was automated test scripts using UICoder. That it is getting popular day by day would be an understatement, and though it is yet a long way to go for it to eventually become a standard tool in the field of Automation Testing, it is by far one of the most sought after tools already.
C1Gauge (SL and WPF) provides pointers to display values in a range. You may want to change the value by dragging the pointer to a specified value, just like a simple slider control behaves.

Last week, I did a webcast on building Grids with Wijmo and ASP.NET MVC. If you didn’t get a chance to see it, the video should be available soon. However, this blog post is designed to tell you everything you need to know about using Wijmo Grids in your applications.
Stacking plot areas within a chart can be a useful way to better analyze the data points. Rather than having many data series overlapped you can increase readability by moving some series to an adjacent plot area. This can all be achieved using the advanced capabilities of the ComponentOne Chart for XAML.
