    Caveats with WPF dynamic resources and animations.

    Recently we've been building some cool stuff in WPF with resources and animations. In this post I will share some experience with a bug from our code base I fought recently. The actual code is complex, so here is a simple example that I used when hunting the nasty bug (source code is in the bottom of the page): <Window x:Class="WpfApplication1.Window1"    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    Title="Window1" Height="300" Width="300">     <Window.Resources>         <Style TargetType="{x:Type Rectangle}" x:Key="RectangleStyle">             <Setter Property="Fill" Value="Blue" />         </Style>     </Window.Resources>     <Grid Name="testGrid" >        ...

    Tip of the Day: Clear your ClickOnce application store

    ClickOnce is a great technology that blurs the line between web and client(windows) applications. You can use it to easily deploy windows forms and WPF (through XBAP) app's. However there is common problem with it. The application store (the place where all ClickOnce applications get stored) has the ability to corrupt it self ending in an appropriate version mix of your application. You can end up in situation where "it works on my machine", but in reality the application did not work correctly. To avoid such situation it is a good practice to clear your application store before testing the...

    Formatting RadChart Labels

    Hi everyone, My name is Vesselin Georgiev and I am a technical consultant here at Telerik. This is my first blog post and it is dedicated to labels in RadChart. By default RadChart will display the value corresponding to the bar (point, slice) as a label.  But RadChart allows you to control the label content. This is possible thanks to the DefaultLabelValue property, which has been around for quite some time now. You can use several “special words” in this property -- "#Y", "#X", “#%”, “#SUM”, “#STSUM”, “#SERIES”, “#ITEM”. They are all listed in the dedicated help topic . This is all good, but...

    WPF Data Binding: Unraveling data templates

    Data binding in WPF in general and particularly working with data templates tends to be quite tricky some times. Here I'll present you some more advanced tips for dealing with data templates.

If you are just starting to work with WPF or you have never met with data templates, please read it first to get acquainted with the idea. I'll use ItemsControl for...

    WPF: Custom control style and theme resources

    Hi everyone. I'm Jordan Dimitrov from the WPF team. I'm planning to post about .Net, first with few post about WPF. My first post is about resources and themes. Recently I had a problem with resources from themes files. I tried to use DynamicResource markup extension in Style in generic.xaml (sample bellow). But it didn't work. I changed DynamicResource extension with StaticResource markup extension and now it works. But WHY DynamicResource doesn't work? Sample XAML In my generic.xaml there are two items - a style for my CustomControl1 and a resource SolidColorBrush with key brush1.     1 <ResourceDictionary     2    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     3    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     4    xmlns:local="clr-namespace:WpfApplication1">    ...
