Silverlight Quick Tip: How to force re-binding

Today I’ll show how to do “dirty trick” to force re-binding and as a result UI value updating. First of all – the reasonable question – “Why force rebinding? Why not use INotifyPropertyChanged mechanism?” This was my questions also, but the person who asked the question had his reasons: he is using resources (Resx) to localize the application and bind the UI to those resources.

Silverlight 2 applications: a day after Silverlight 3 release

Silverlight 3 release date is approaching, and I’m getting questions what will happen to existing Silverlight 2 applications after it will be released. Also I’m getting questions about the runtime version upgrade. Let’s see what will happen after Silverlight 3 will be released… Those who already using Silverlight 2 and getting automatic updates will receive the new runtime automatically. Everyone else need to download and install it manually. The updated clients will be able to run Silverlight 2...

Silverlight Quick Tip: How to change Tab Items order

When adding the TabItem to the Tab control dynamically (from code behind for example) the TabItems will be added in the order they added. Here is the simple solution of hot change the order of already added tabs. In my case I have simple XAML with Tab Control: < controls : TabControl Width ="400" Height ="200" x : Name ="tabs" Margin ="5">...
