    Maximizing space with RadExpander for WPF

    When designing an application a challenge that all user interfaces must contend with is available screen real estate.  While you want to maximize the information available to the user, you also want to avoid visual overload.  There are a variety of controls available that allow you to minimize the impact of options on a form.  For example, the RadioButtons below display three options for the user, but for each option you take up valuable screen real estate.  A ComboBox offers the same choices to the user when expanded, but takes up minimal space on the form when not being used. ...

    Performance Monitor using RadChart for WinForms

    I have had a few people ask me about using the RadChart in the same manner as Performance Monitor (aka PerfMon). If you are not familiar with PerfMon, it is a tool that has been provided with Microsoft Windows for quite some time. You can open PerfMon by clicking the Start button within Windows, typing “perfmon” in the search box and pressing Enter.  PerfMon is a simple utility that displays performance counters. There are a wide variety of counters available, from CPU utilization of process threads to how many times the .NET Garbage Collector has run. The counters PerfMon allows...

    WPF / Silverlight: RadChart PointMark Customization

    RadChart supported point mark visual indicators for chart series like Line, Area, Spline, etc. from version one, however, customization of these indicators was hard and certainly not for the faint-hearted.

    Change the Office Black theme to support multiple Linear Scales using Expression Blend

    I recently posted an entry regarding the Radial Gauge for WPF where I demonstrated how you can create a half circle gauge.  Not long after that post, I received a question asking about Linear Gauges and how to use multiple scales in a single Linear Gauge.  It is not that there is a functional difference, but rather a visual difference.  The Office Black theme (shown below) has a border area in the middle where the linear gauges were overlapping causing a visual collision.  There are a number of ways that you can accomplish a task and I think one of...

    Installing and Using the RadRibbonForm template

    If you are planning to use the RadRibbonBar and want to get started quickly, then you might consider using the RadRibbonForm template in VIsual Studio.  While you can use a standard form the RadRibbonForm allows you to use the RadRibbonBar and have it extend into the Title bar, just like Microsoft Office.  You will first need to install the template so it is available to you in Visual Studio.  To get started, navigate to the C:\Program Files\Telerik\RadControls for WinForms [version]\Templates.  If you are using CSharp open the CSharp directory, there are Visual Basic versions as well, in appropriately named folders,...
