Ever want to filter data in Silverlight? here's a simple example that uses a lambda expression to search on name (case sensitive)
ComboBox cbx = ((ComboBox)sender);
ICollectionView dataView =
CollectionViewSource.GetDefaultView(this.DataContext);
if (!string.IsNullOrEmpty(cbx.Text))
dataView.Filter = f => ((Job)f).Name.Contains(cbx.Text);
else
dataView.Filter = null;
