Hi

When working with WPF I always found myself thinking how to handle Data formatting when a WPF control was bound to it. Let’s look at the following example of a window with a TextBlock that displays a DateTime:

   1: <Window x:Class="BindingFormat.Window1"

   2:     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

   3:     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

   4:     Title="Window1" Height="300" Width="300">

   5:     <Grid>

   6:         <TextBlock Text="{Binding}"></TextBlock>

   7:     </Grid>

   8: </Window>

And it is really something like this until you decide you want to have transparent outlined bullets or opaque bullets with transparent outline around them. Like the ones in this picture:

Let me share you with one of the weirdest errors I ever encountered. Recently, I have been working on a distributed application which is built from a server and some clients. The clients are Windows Forms applications. Yesterday, I spent a whole day chasing a very weird and strange error - I was getting an exception at the main method (unhandled exception) of the client application. Here is what I got:

Hi

Recently I’ve been working on a set of custom WPF controls.

There are numerous good books and articles about WPF in general and some basic information on custom control development but I have yet to find a good article (or book) with in-depth coverage of custom control development in general and design-time related issues in particular.
