Create a Login Window in WPF (2013)
One of my most widely-read blog posts had to do with creating a Login Windows in WPF that I wrote several years ago. I thought I would revisit this login screen with an updated version in Visual Studio 2012 and with an updated look and feel.

Creating a XAML Tile Control
One of the navigation mechanisms used in Windows 8 and Windows Phone is a Tile. A tile is a large rectangle that can have words and pictures that a user can click on. You can build your own version of a Tile in your WPF or Silverlight applications using a User Control. With just a little bit of XAML and a little bit of code-behind you can create a navigation system like that shown in Figure 1.

A WPF Image/Text Button
Some of our customers are asking us to give them a Windows 8 look and feel for their applications. This includes things like buttons, tiles, application bars, and other features. In this blog post I will describe how to create a button that looks similar to those you will find in a Windows 8 application bar.

A WPF Image Button
Instead of a normal button with words, sometimes you want a button that is just graphical. Yes, you can put an Image control in the Content of a normal Button control, but you still have the button outline, and trying to change the style can be rather difficult. Instead I like creating a user control that simulates a button, but just accepts an image. Figure 1 shows an example of three of these custom user controls to represent minimize, maximize and close buttons for a borderless window. Notice the highlighted image button has a gray rectangle around it. You will learn how to highlight using the VisualStateManager in this blog post.

A Communication System for XAML Applications
In any application, you want to keep the coupling between any two or more objects as loose as possible. Coupling happens when one class contains a property that is used in another class, or uses another class in one of its methods. If you have this situation, then this is called strong or tight coupling. One popular design pattern to help with keeping objects loosely coupled is called the Mediator design pattern. The basics of this pattern are very simple; avoid one object directly talking to another object, and instead use another class to mediate between the two. As with most of my blog posts, the purpose is to introduce you to a simple approach to using a message broker, not all of the fine details.

A WPF Message Box you can Style
You go to great pains to add styles, colors, gradients, and a really cool look and feel to your WPF application only to have that ruined by the standard Windows message box as shown in Figure 1.

Create your own WPF Button User Controls
In Figure 1 you can see examples of the standard WPF Button controls. You can add a drop shadow and you can change the color, but you can’t change much else without creating a whole new control template. For example, you are unable to modify the BorderBrush or the BorderThickness properties of the Button control. Additionally you might want to use some other animation than the default, which again requires you to change the control template.

WPF Tree View with Multiple Levels
Earlier this year I blogged on how to use the WPF Tree View to view multiple levels. Since then I have had many requests to do the same in WPF. Luckily, the code is almost identical. Here is a blog post on using the WPF Tree View that has multiple levels.

Understanding XAML Screen Layout
When you first start designing XAML screens in either WPF or Silverlight there are several approaches you can take. You can just draw controls on a Grid and let the controls figure out where they are in relation to one another and the Window via the Margin property. You can also a Grid and create a set of Row and Column definitions similar to an HTML table. Another method is to use absolute positioning with a Canvas control. Finally, you could use a series of StackPanel controls with styles. Which one you choose has ramifications to how well your application looks and feels across a wide variety of resolution sizes. This article will explore the impact of each of these.

Synch a ComboBox in WPF with Foreign Keys
In most database applications you will have foreign keys to express a relationship between one table and another. Many times this takes the form of a lookup table where you want the user to pick from a selection of items such as an Employee Type for an Employee record. You don’t want to have the user remember a number such as 1, 2, or 3, but instead they will pick from a list of the description that corresponds to these numbers such as “Manager”, “Project Manager”, or Employee. While you want to display these descriptions in a ComboBox, like that shown in Figure 1, you want to store the Employee Type ID number into your Employee table to make the data smaller and make it more efficient to join between the two tables.

The Basics of MVVM in WPF
This is a follow-up to my previous blog post on the Basics of MVVM in which I used Silverlight to illustrate how to use a basic MVVM design. I had so many emails asking for a WPF version, I decided to post this sample using WPF.

UserAppDataPath in WPF
In Windows Forms applications you were able to get to your user's roaming profile directory very easily using the Application.UserAppDataPath property. This folder allows you to store information for your program in a custom folder specifically for your program. The format of this directory looks like this:
