Random Bits

Finally got time to update the expired video links (silverlight streaming) in my previous posts. Setting into my new job , the future looks exciting, hopefully I will have time for some good posts.

This is a Behavior I created to allow Drag and reposition items in WPF Control that extend ItemsControl. After applying this behavior the user can at runtime click and drag any item while holding the control key. I created this behavior to support a application which required ability for the users to reposition items like icons on a desktop. Here is the screen cast of the sample application demonstrating this.

  Have you ever pulled out your hair trying to figure out why / why not a particular value is (or not) being set on your control , what was wrong with the binding? I have seen people suggest exotic solutions where in there used a special converter so that they can debug the value being bound, or turn-on WPF tracing which generates a huge volume of trace statements that you will have to filter, well i found a easier way to debug just the one binding that matters by specifying a  binding attribute. 1: < UserControl 2: xmlns:diag ="clr-namespace:System.Diagnostics;assembly=WindowsBase" > 3: ... 4: ... 5: < Grid > 6: < TextBlock VerticalAlignment ="Center" Text ="{Binding Name,diag:PresentationTraceSources.TraceLevel=High}" /> 7: </ Grid >   this produces following output in your trace log 1: System.Windows.Data Warning: 54 : Path: 'Name'

and here is how it was made…

Here is the screen cast of demo which was built on top of the sliverlight application framework that I was working on for sapient labs. we will be hosting this application on the cloud (azure) shortly… Part 1 Part 2

Looks like VS 2010 editor and the blend editor have some code base.. I was pleasantly surprised to see C# intellisense in blend, I was only expecting XAML intellisense.
