WPF Quick Tip: How to get WPF Window client area size

Sunday, September 20, 2009

This time my quick tip will be not about the Silverlight, but about WPF. When you have WPF window, the runtime size of it could be discovered by ActualWidth/ActualHeight properties. In most cases this is enough. But what about the case, when you need to perform some mathematical calculations based on the real size of client area? What is this client area? Well, the second question is really easy one – the client area is the area available to user defined UI (controls, panes, etc.): At the screenshot - client area is...

Quick Tip: LINQ & Data Binding notifications

Tuesday, June 23, 2009

In Silverlight & WPF we could databind to the LINQ query results: private ObservableCollection<string> someData = new ObservableCollection<string>(); //Somewhere in code someData.Add("Alex"); someData.Add("Alen"); someData.Add("Josh"); someData.Add("Brad"); var res = from data in someData            where data.StartsWith("A")            select data; listbox.ItemsSource = res; ”listbox” is the name of the Listbox on my XAML page. When application will load we will get expected results: But what happens when out collection (reminder: ObservableCollection, which implements INotifyCollectionChanged) changed? someData.Add("Antony"); Nothing! Because we bounded to the LINQ query (predicate), and the query was executed...

Path.Data Dependency Property Initialization From String

Monday, June 16, 2008

In Silverlight 2 Beta 1 I used to build dynamic UI with drawing portions. For example, I used to draw Path dynamically like in following example: Path myPath = new Path(); myPath.SetValue(Path.DataProperty, "M 50,50 L 50,100 L 100,100 L 100,50 L 50,50 Z"); myPath.SetValue(Path.NameProperty, "myPath"); myPath.Width = 100; myPath.Height = 100; myPath.Fill = new SolidColorBrush(Colors.Black); LayoutRoot.Children.Add(myPath); This gave me nice rectangle... Everything was fine, until I start to port my project to Silverlight 2 Beta 2. After fixing all known stuff, I finally executed the application and in the moment I expected to get some nice Path being drawn I've got exception: What happened? Why? It...
