This also happens if I just set "MyCollection" to another ObservableCollection.

If I have a List with a bunch of elements... List<string> TestSet1 = new List<string>() { "one", "two", "three", "four", "five", }; And an ObservableCollection initialized to that List of items... public ObservableCollection<string> MyCollection { ge...

First I tried it this way, as per another forum post I saw: <UserControl x:Class="Controls.SoftButton.SoftButtonControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namesp...

I have a ListView control defined like this: <ListView x:Name="CurrentDirectoryListView" SelectionMode="Single" Style="{StaticResource FileManagerListViewStyle}" ItemContainerStyle="{StaticResource FileManagerListViewItemStyle}" ItemsSource="{Binding Curr...

Actually no... I'm getting periodic IOExceptions when I try to delete files which I'm displaying as thumbnails in my file manager view. I think you have to explicitly Dispose the stream. Normally I would wrap this line in a using block to ensure it's Disposed when out of scope, but if I do that, it ...

And 2 minutes later I realized I could add "FileShare.Delete" to the FileStream call:

So we have this custom FileTextureProvide which can create resources from the filesystem public class FileSystemTextureProvider : FileTextureProvider { ... public override Stream OpenStream(string path) { ... return new FileStream(path, FileMode.Open, FileAccess.Read); } That code is triggered when ...

I have the following attached property which works fine if it's defined locally... public static class FocusExtension { public static bool GetIsFocused(DependencyObject obj) { return (bool)obj.GetValue(IsFocusedProperty); } public static void SetIsFocused(DependencyObject obj, bool value) { obj.SetV...
