Thank you for the link, although it seems what I need to achieve cannot be done - at least not with C#. Looks like I have to save the function definition in an attribute. D'oh

Thank you! Seems to work (just tried it with a short piece of code - going to check it within my project later).

That's pretty cool - thanks your your support. That and your first sample helped me to got it solved. First I used a few reflections for the type passing, but now I think I'm going to make use of your implementation. Thank you again!

Why don't you try inheriting the Style itself? Silverlight 5 Tutorials :   1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9

Have you tried WritableBitmap? you can return a empty WritableBitmap, start a thread to load your URI, then when the loading is finished, update it back through Dispatcher : writeBitmap.Dispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate { //UI Thread Int32Rect outRect = new Int32Rect(0, (int)(writeBitmap.Height - height) / 2, width, height); writeBitmap.WritePixels(outRect, bits, stride, 0); })); Thats what I did for my FileToIconConverter. QuickZip

Thank you! That did it: '<%# DataBinder.Eval(DataItem.vm,"TestValue")%>' and defining public DefaultVM vm;

They don't need to be DependencyPropety's to be bound. There's a lightweight way of achieving what you want using POCO's. If you take a look at my sample here[^], you'll see that I'm handling the validation based on a ViewModel, which is totally none-DP based. "WPF has many lovers.

The problem looks like it's associated with recursive usage of the same DataContext instance during the SubmitChanges() execution in your code. Try to create a new context instance each time you need to save a log.

Then write your own in B, and then translate.

Thanks for your solution

Hi, of course, you can add an object to the timer. but you must recognize that 'timer Thread' is not the same to 'main Thread', so after you create the object in 'timer thread', if you use it in 'main thread', will throw an error.

Thanks! That did it!

Thank you!

Thank you very much! Helps me a lot!

Bind ListBox's SelectedIndex to Count property (of the ObservableCollection) . In the binding you would have to use a converter to return a Count - 1 value. Something like this, <ListView Name="listView" ItemsSource="{Binding}" SelectedIndex="{Binding Path=.Count, Mode=OneWay, Converter={StaticResource SelectedIndexConverter}}" > <ListView.ItemTemplate> <DataTemplate> <TextBox Text="{Binding Path=FirstName}"></TextBox> </DataTemplate> </ListView.ItemTemplate> </ListView> The Converter will get the current count value and it will return a Count - 1 value. public class SelectedIndexConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { return (object)(System.Convert.ToInt32(value) - 1 ); } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new Exception("The method or operation is not implemented."); } }

Found only System.Windows.Forms.AllScreens which can be used but is not how I really like it to be done. The reason is I'm using WPF, and just for this using the Windows.Forms is a pain. Has anyone an idea of how much extra RAM I need for using Windows.Forms just for one function? As far as I've ssen there aren't really any alternatives (except using unmanaged code and p/invoke) but this is the least think I really want to do (beyond using e.g NVIDIA APIs). More ideas are welcome! ;) greets, eza
