    Pick your time with RadTimePicker for WinForms

    Q1 2012 is knocking on the door and we are sure you want to grab it as soon as possible. Before the release itself is live, however, let us introduce yet another useful editor that will find place in your fill-in forms. This editor will allow you to pick the time from a convenient grid of hours and minutes. Reasonably, we called this control RadTimePicker. In addition to the grid, RadTimePicker will also expose a beautifully crafted analog watch that will serve as a time reference to the end-user. Moreover, RadTimePicker will support different cultures for its editor part, and you...

    XAMLflix Marches On with RadScheduleView for Silverlight and WPF

    It's Thursday again, which means we're ready for another installment of... XAMLflix! If you haven't tuned in over the last few weeks to our RadChartView and RadBarCode posts, my partner in crime (Michael Crump) and I have been working on a new initiative to help accelerate your education when it comes to the RadControls for Silverlight and RadControls for WPF control suites. XAMLflix is intended to deliver quick, to-the-point videos highlighting features and functionality of our controls alongside sample projects with the exact code you are seeing in the videos.

    About RadTreeView for WinForms and its Supercharged engine

    In Q1 2011 we introduced a highly improved version of the RadTreeView control which had all of its internal parts rebuilt in order to support full UI virtualization and customization. This allowed us to attach a new data engine that provided many new and useful features such as built-in filtering and sorting independent from the external data-sources, and support for CRUD operations. For Q3 2011 and Q3 2011 SP1 we made additional improvements to our data engine and in the synchronization between the UI and the data layers. Now, there are two questions which we have been asked lately: “Is the new RadTreeView...

    RadMap for Silverlight / WPF: How to resize map shapes with mouse dragging

    RadMap provides a rich set of geocoordinate-enabled shapes that can be defined and displayed onto the map surface .There are scenarios, however, where you would like to do more than just position a shape onto the map. This blogpost will demonstrate how to manipulate each individual segment of line/polyline/polygon shape based on mouse input from the user. For example we will select (highlight) a point, and drag the selected object to another location on the map – modifying in this way the shape or the line segment. First of all we’ll need two Information layers – one...

    Filtering Collection Properties with RadGridView for Silverlight and WPF

    By default, RadGridView will not be able to filter properties which are IEnumerable. However, with two of its features you can easily add this custom functionality. The first feature you need to use are the Custom Filtering Controls which I have explained in one of my earlier blog posts so I will not go into detail here. The focus of this blog is how to implement the IFilterDescriptor interface so that our data engine can filter your enumerable property. This interface allows you to provide a filtering expression. This expression will be used when the data engine performs the actual filtering. In the...
