NuExt.Presentation.Wpf 0.7.5

NuExt.Presentation.Wpf

NuExt.Presentation.Wpf is a lightweight, WPF-focused presentation library providing XAML helpers, control extensions, data-binding utilities, diagnostics, and templating helpers. It enables clean, reusable presentation code across WPF applications with minimal dependencies.

Highlights

• Control extensions — TreeViewItemHelper, ComboBoxExtensions, VirtualizingStackPanelExtensions, ControlExtensions for common WPF control operations.
• Binding helpers — BindingProxy and BindingProxy<T> to pass DataContext across templates and containers without direct binding paths.
• Framework extensions — FrameworkElementExtensions, DependencyObjectExtensions, WindowExtensions for element and window operations.
• Window placement — WindowPlacement to save/restore window position, size, and state with minimal code.
• Diagnostics — BindingErrorTraceListener to capture and display WPF binding errors in debug builds.
• Templating — ComboBoxItemTemplateSelector and reusable XAML styles (TreeViewItem, etc.).
• Zero heavy dependencies — only depends on NuExt.System and WPF framework types.

Compatibility

WPF on .NET 8/9/10 and .NET Framework 4.6.2+. Platform-independent usage patterns suitable for any MVVM framework.

Quick Start

Binding across templates with BindingProxy

<Window.Resources>
    <local:BindingProxy x:Key="proxy" DataContext="{Binding SomeViewModel}" />
</Window.Resources>

<Grid DataContext="{Binding Source={StaticResource proxy}, Path=DataContext}">
    
</Grid>

Enable binding error diagnostics

protected override void OnStartup(StartupEventArgs e)
{
    base.OnStartup(e);
    PresentationTraceSources.Refresh();
    PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.Warning;
    PresentationTraceSources.DataBindingSource.Listeners.Add(new BindingErrorTraceListener());
}

Save/restore window placement

var placement = WindowPlacement.GetPlacement(windowHandle);
// ... later, restore
WindowPlacement.SetPlacement(windowHandle, placement);

Find TreeViewItem by data item

var treeView = ...;
var item = treeView.GetTreeViewItem(myDataItem);
if (item != null) item.IsSelected = true;
