    Twitter Authentication with TweetSharp and WinForms

    A few weeks ago, I decided to spend some more time experimenting with the Twitter API and TweetSharp. If you missed my last blog entry about it, you can access it here. Last time I focused on creating a simple UserControl for ASP.NET that displayed recent tweets. It didn’t require any authentication and was actually quite simple to implement. This time around, I wanted to create a RadControls for WinForms based application that retrieved information about my accounts followers. This type of information is unfortunately not publically accessible through the API. You actually need to authenticate and log ...

    Blend, DevConnections, and Lighting Up The Web

    Hey Telerik Developers! I wanted to write a slightly out-of-band post to mention some of the speaking engagements that I will have over the next few months, covering a wide range of topics in the Silverlight and Windows Phone 7 space. First up, Telerik is pleased to host Expression Blend for Silverlight Developers, a one hour webinar being presented on October 21st aimed at helping the Telerik Developer Community (and for that matter, everyone using Silverlight, WPF, or Windows Phone 7) to learn a little bit more about Expression Blend and how it can fit into our daily development workflows.  You can...

    Following up from New England Code Camp 14

    Hey Telerik Developer Community!  If you are in the northeastern US (or even further, if you look at the speakers!), then you probably spent this past Saturday afternoon at New England Code Camp 14 for a day jam packed with great topics and conversations. I was able to present Building a Unified Experience - Developing with Silverlight 4 and Windows Phone 7 at NECC and had a great time of it- the audience seemed to get into the talk as well with tons of questions regarding the framework, the future of WP7, and the launch that we all know is coming...

    Displaying Incremental DateTime Values in the X-Axis of RadChart

    One of RadChart’s most powerful features is its support for DataBinding. This means that as long as you correctly format your data source, you shouldn’t have to write any backend code to support the generation of the chart. Using a data source with a control as powerful and complex as the RadChart can unfortunately be somewhat confusing. In this post, I’ll shed some light on one of the scenarios you are sure to come across, displaying incremental DateTime values from a data source in the X-Axis of RadChart. Setting Up the Data Source RadChart does not work directly with DateTime ...

    Fast real-time data update for your Silverlight and WPF applications

    I’ve made small example to illustrate how to use NotifyCollectionChangedAction.Replace in order to provide very fast real-time data update with RadGridView for Silverlight and WPF.    While Binding in both Silverlight and WPF will react immediately to any property change of INotifyPropertyChanged object and will update RadGridView cell values sometimes it is important to refresh the grid in order to update a sorting, filtering, grouping, etc. after some value change. To achieve your goal in such situation you have two options:   - listen for PropertyChanged of every item in the collection and raise NotifyCollectionChangedAction.Reset for the collection in order to tell the...

    Using Shapefiles with RadMap

    Since the introduction of RadMap many customers have expressed a need to load shapefiles onto it.  We are adding native support for shapefiles in the Q3 Release, along with vastly improving the performance of information, and dynamic layers.  However, the beta is still a few weeks away, and I had a need for loading shapefiles this week, so I put this quick example together. How to do it Shapefile parsing in this demo is handled by the reader available in the ESRI Contrib project.  When we make the Q3 release you will be able to switch over to our reader by changing about...

    RadChart for Silverlight in ASP.NET MVC Application

    The purpose of this blog post is to show how to incorporate RadChart for Silverlight in an ASP.NET MVC application. Manol has already shown how to do this for ASP.NET and things are not much different for ASP.NET MVC. Let’s start with a simple Silverlight application with a single RadChart. For simplicity, I will populate it with a list of numbers, you can also use any of the techniques, supported by RadChart. The code is as simple as this XAML: <telerik:RadChart x:Name="RadChart1" /> And C#: RadChart1.ItemsSource = new double[] { 3d, 4d, 6d };   I will create two write-only properties of the Silverlight user control -- ShowItemLabels and SeriesType. They are marked with  ScriptableMemberAttribute so...
