    Displaying Hierarchy in RadGridView for WPF

    Building on my previous post where I talked about how to bind data to the RadGridView, today I want to show how you can display hierarchical data in the grid.  I will follow the same concept of building an application for a car repair shop to manage vehicles in for repair.  I will leverage two classes to display the data.  The original Car class which was used previously and a new CustomerComplaint class.  The Complaint property of the Car object was initially a string, but we need to allow for several issues to be reported so we will use the CustomerComplaint class to...

    Displaying data quickly in the RadGridView for WPF

    The RadGridView for WPF uses the ItemsSource property for binding data.  ItemsSource is actually of type System.Object which not only allows you to bind to any data source that implements IEnumerable, but also the ADO.NET DataTable and DataSet.  In this post, I am going to demonstrate how you can quickly bind data to the RadGridView for WPF.  The task will be to build a car repair shop application which will display all the cars currently in the shop.  To get started we need to have some data, so we will use a simple class to store Car information.       public class Car       {           public string Make { get; set; }...

    Grouping data in the RadGridView for WPF

    When you first add the RadGridView to your WPF application you will undoubtedly notice the section at the top of the control which I have outlined in red.  This area is officially called the GridViewGroupPanel, but I am just going to call it the Group Panel to save myself some typing.  The Group Panel allows the user to drag and drop column headers into the panel in order to group the data in the RadGridView at runtime.  Below you will see that I have grouped my data by the "Make" column in my grid of vehicles. Additionally, the sort order of...

    Implementing the RadNumericUpDown for WPF

    I am sure that you are wondering why I would spend time blogging about implementing a control as simple as the RadNumericUpDown for WPF.  After all this is not a complex control and if you have done any client development you have probably used a NumericUpDown in the past.  Well, this is not the same control and it does have some nice features that you may not be aware are available.  I thought it might be nice to demonstrate some of these features. So most likely you have used the WinForms version of NumericUpDown and were limited to only a few...

    Customizing the Radial RadGauge

    Hello everyone and happy new year. Today I decided to break the lengthy silence on my blog with an example on how to customize the RadGauge. Since there were a couple of requests for custom Radial Gauge, I will present a way to create a semi-circle gauge. That is generally achieved in two steps: Customize the radial scale range Four parameters define the radial scale range: StartAngle, SweepAngle, Radius and Center. The StartAngle and SweepAngle are specified in degrees (0 to 360), starting from the right side of the gauge, going clockwise (note, that positive angle direction is starts from positive X and goes to the positive...
