    Mark working hours and days in different colors with RadScheduler for Silverlight

    We received a couple of questions on how some of the days and hours in the different views of RadScheduler can be customized. The answer of this question is in the attached application illustrating how working hours and days can be  marked in orange.  The solution includes 3 easy steps : Create a custom theme using the default RadScheduler' theme. Create a ValueConverter returning the right color depending on the hour/day. Find the style applied to every hour(timeslot) and apply the converter to the Background property. To create a custom theme you can follow the steps...

    Drag and drop items onto RadScheduler for Silverlight

    We all are aware that users tend to look for the easiest and most rational way to do something. That is why developers always strive to create their products' interface as intuitive as possible. Speaking in this context, dragging and dropping helps us improve user experience significantly and make end users happier. In this blog post I will explain how we can use RadDragAndDrop to enable users drag items from a certain control and drop them over RadScheduler, while notifying about that. Of course, the described scenario could be extended to act in many different scenarios. Let us say we will drag items from a listbox to...

    RadDrag&Drop with a Canvas twist

    August 18, 2009 Share
    A week or so ago I was giving a small presentation and one of the people in the audience had a great question.  They had this old configuration section on their website for laying out something or other that had a lot of different options which could be dragged and dropped using some client-side javascript, but they are looking to move on up to Silverlight and the RadDragAndDropManager seemed to be the perfect candidate for the job.  The only issue with that is the only examples we have online show moving items to and from collections, but in their case...

    RadioButton and CheckBox Menu Items with RadMenu for Silverlight

    June 19, 2009 Share
    RadMenu for Silverlight supports simple checkable items, but still does not support radio button items. This feature is scheduled for development and most probably will come with Q3 2009, but until then you have to code it by yourself. Fortunately, this is relatively easy with a proper ViewModel, that contains the radio-button logic: The CommandItem class contains the properties and the logic for a RadMenuItem. It implements INotifyPropertyChanged and its most important property is IsChecked: public bool IsChecked { get { return this.isChecked; } set ...

    Scrollable Menu – Workaround with a Multi-Column Menu and RadControls for Silverlight

    June 18, 2009 Share
    RadMenu and RadContextMenu for Silverlight cannot automatically scroll their items if their height exceeds a certain height. We are planning to implement this feature in the near future, but at the moment there are two workarounds for the developers: override the RadMenu control template and add ScrollViewer controls around the ItemsPresenters, or customize the ItemsPanel of the RadMenuItem controls, so the sub-items are displayed in columns. The second option is much easier and looks good enough: The main idea is to replace the RadMenuItem ItemsPanel, that is a StackPanel by default, with a WrapPanel. To set the ItemsPanel property of all...
