When C1GridView is bound to a datasource, the columns are auto generated. Disabling sorting on a particular column is difficult as there are no boundfields or templatefields specifically coded - its all AUTOgenerated.
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.
Wijmo v2 is here! Yay! For today’s Wijmo Wednesday, let’s take a look at a new Wijmo v2 feature: Linear Gauges. Getting Started To get started, we need to create a new DIV for the gauge to live in. <div id="gauge"></div>

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.
C1Report is a powerful reporting tool, which provides a large scope of customizations that we can do on the ReportDefinition, create using this control.
C1Tabs provides a fantastic way to show your content in Tabs and moreover can put in anything as the content of a C1TabPage. This blog provides an easy way to add an Image in the Header of each C1TabPage (apart from the usual text) that gives them an idea of what that tab contains. You can easily accomplish this with just as little as 4-5 lines of code using jQuery.
Silverlight has been a revolution when it comes to the flexibility of designing and changing the UI of an application. Silverlight suite from ComponentOne leverages on this advantage to provide further customization options to its users.
Silverlight 5 has introduced a lot of new features and one of them is the ability to set binding on Style Setters. This great feature was heavily missing from the earlier Silverlight version. The functionality is pretty useful and is extensively used in WPF applications.
