In a previous post I demonstrated how you can display photos from the server inside Silverlight and using C1CoverFlow to create an interactive photo gallery. Using C1CoverFlow gives you a familiar iTunes UI, but the one limitation is that the photos can’t be expanded (without some significant more work). In this post I’ll demonstrate how you can use the new C1TileView control to create a photo gallery with minimize/maximize functionality. In this post I’m leaving out the code which loads images from the server using an XML file, but you can take that from the previous post and apply it to this one yourself if you are interested enough.
C1Flexgrid does not expose any direct method for exporting to excel, but you can easily achieve the functionality using helper classes provides with the 'ExcelGrid' (Silverlight) sample.
Our release of two Wijmo-powered ASP.NET studios represents a new day in ASP.NET development, and I’m particularly excited about our Studio for ASP.NET Wijmo. Server controls have been a staple of ASP.NET WebForms development since its inception, and we’ve rewritten our ASP.NET WebForms components to use our Wijmo jQuery UI widgets. Studio for ASP.NET Wijmo contains over 45 controls, including interactive SVG charts(bar, line and pie), a supercharged GridView, and an SSRS-compatible report viewer. To truly experience these components, visit the live demo at http://demo.componentone.com/ASPNET/ControlExplorer/. Try it on any browser, even an iPad. You can build cross-browser, cross-platform applications using the ASP.NET WebForms skills you have.
With Studio for WPF and Silverlight 2011 v2, you can now broaden your global audience with built-in localization support for 20+ international languages. This means that all UI strings baked into ComponentOne WPF and Silverlight controls can be automatically translated into these languages (aside from English):
I could not be happier to announce our latest release of Studio Enterprise. I am proud to say it includes a completely new Web Stack for any flavor of Web development. As you know we have recently created a whole new framework for pure client-side development called Wijmo. We wrote it to be a core technology for ComponentOne based on the latest standards like HTML5, CSS3 and jQuery.
Many of our customers have faced a problem in C1GridView that the data rows are displayed on top of the headers when the grid is scrolled vertically. The issue is observed when few columns of the grid are fixed and the Paging is enabled in such a way that the Pager is shown above the column headers. The problem only occurs when compatibility mode is enabled in IE8/IE9, or in the old versions of Internet Explorers (IE6/IE7).
We just released a CTP of our newest dev tool: Studio for Entity Framework. This set of data binding components is built on top of the powerful ADO.NET Entity Framework to make things simpler and even more powerful. Studio for Entity Framework includes 1 key design-time component, C1DataSource, which can be used with your already existing entity data models. You don't have to change the way you're handling your data; you simply plug C1DataSource into the view layer.
We have been hard at work getting Wijmo releases out the door. It's hard to believe we are already at 1.3.0! This release has an awesome new widget, a bunch of cool new features and a few breaking changes.
We have always been quick to build UI controls on top of new Microsoft technologies as they emerge. A little over a year ago, we started experimenting in ASP.NET MVC. After a lot of R&D we came to some interesting conclusions. This is the story of Studio for MVC Wijmo and how it came to be...
ComponentOne ClearStyle technology is one of the most unique and useful features of Studio for Silverlight and WPF. ClearStyle makes styling controls very easy. It allows developers to customize a control's appearance (ie colors) without having to hassle with XAML templates and Expression Blend. You can fully customize the style of any ComponentOne control right on the Visual Studio 2010 design surface thanks to ClearStyle. And the best thing is that ClearStyle is baked into the C1 controls, so there's nothing new you have to learn. This blog post explains how you can take advantage of ClearStyle and save time styling your applications.
As a general rule, Silverlight/WPF performance degrades with an increase in the number of objects in visual tree. For instance, take the LineSymbol Chart. When a large number of data points are plotted, the rendering is slow, as the large number of datapoint Symbols makes the visual tree quite large. In extreme cases, this can even make user interaction quite difficult.
There are times when user wants to see only a limited amount of data in the datagrid. This would obviosuly enhance the performance in case of very large data being that the whole data is not always loaded.
This article will discuss one of the ways to implement antivirus file scanning using C1Upload in the ASP.Net applications. Viruses, Trojan Horses, and different malware and spyware pose a real problem for current computer environments, and especially for the Windows operating system. If you are designing any application in .Net that is required to be able to upload external files, you have a potential security risk. It is quite common to have this type of requirement in a web application.
We have just unveiled the CTP of our new Studio for Windows Phone. For this first release, we've taken several of our popular Silverlight 4 controls and ported them to the Silverlight for Phone platform. These controls are designed to extend and enhance the Windows Phone tools by providing advanced controls (such as Charts and RichTextBox) and filling the gap with other common, missing controls.
