  1. Change the PropertyChangeTracker.OnPropertyInvalidation method to raise Changed event with meaningful EventArgs object...

    Change the MS.Internal.ComponentModel.PropertyChangeTracker.OnPropertyInvalidation method to raise Changed event with meaningful EventArgs object, which tells which DependencyProperty is changed.

    I am using the following code-construct to wire-up event handler for DependencyProperty changes:

    public void WireUp( DependencyObject obj, DependencyProperty prop )
    {
    var dpd = DependencyPropertyDescriptor.FromProperty( prop, obj.GetType() );
    dpd.AddValueChanged( obj, ValueChangedEventHandler );
    }
    private void ValueChangedEventHandler( object sender, EventArgs e )
    {

    }

    Unfortunately the EventArgs e represents an EventArgs.Empty object inside the event handler method block, which makes impossible to track which DependencyProperty was changed.
    As I see in the reference-source (http://referencesource.microsoft.com/#WindowsBase/Base/MS/Internal/ComponentModel/PropertyChangeTracker.cs,6c03ba1a17c9b49b) the MS.Internal.ComponentModel.PropertyChangeTracker.OnPropertyInvalidation method raises the Changed…

    • To use the same Names of Properties in WPF in ASP.NET too

      In WPF you call it Background, but in ASP.NET you use Backcolor and in WPF it is Visibility and in ASP.NET it is Visible. That will the Software engjineer have to know. Probably now is the last Chance to introduce the same names in WPF in ASP.NET too.

      • Declare dependency properties in XAML

        Declaring new dependency properties on my user controls and the like requires so much boilerplate, even with code snippets. (And why not update the snippet to use the nameof operator for the declaring class name if you're using C# 6, anyway? Would make refactoring so much easier!) Anyway, if I could declare dependency properties in XAML, I think that would be much more intuitive.

        • Provide the ability to identify ToolTip (error messages) in Telerik WPF Controls: Coded UI

          The ToolTipText method present in Coded UI is not able to capture error messages which appear on hover. Neither the test builder tool's crosshair nor Ctrl+I combination are able to identify the error message. The reason for this behaviour seems to be design of the control as a hidden control.

          I'm attaching a screenshot of the error message which we try to capture. Here is a link to the MSDN Forums post which I made: https://social.msdn.microsoft.com/Forums/vstudio/en-US/9062a310-918e-40b1-8f7a-3f21e4a5ccbb/method-to-identify-tooltips-in-wpf-controls?forum=vstest

          • Binding

            I can never remember complex bindings, particularly in situations where there is no datacontext available. I would like some shorthand properties that let me bind to the current UserControl, for example. Currently I have to do something like this:

            RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type views:XXXXXView}}

            But I would like to do:

            RelativeSource={UserControl}}

            • Improve XAML styles to be more like CSS

              The main item is multiple style inheritance but it would be nice if people's knowledge of CSS styles could be more portable to XAML.

              • Allow WPF to apply bindings in a non UI thread. Good for reporting templates using FlowDocuments.

                FlowDocuments are wonderful to be used as Reporting Templates through its DataContext property and bindings in its inner elements, but it is important to rely the application of this bindings on background threads when generating documents massively. Right now, the UI is blocked

                  • Add support for TabTip

                    WPF really lacks the option the properly interact with the TabTip keyboard when developing for touch screens. Windows are not aware of it's presence in terms of resizing and closing and opening it requires writing some hack methods.
                    It would be nice to have some built in support for this issues.

                            • Improve WPF popup

                              The WPF popup should behave like it's parent app:

                              If it's parent app is behind another window, the popup should be also.
                              If you switch to another app, you should be able to click on controls in the popup - not have to click on the parent app behind it first.

                              If the official word is "use tooltips or child windows always instead of a popup" then they should be depreciated. I believe right now they are a trap for inexperienced developers because the limitations are so unexpected, leading to a lot of wasted time trying to fix.

                                All free SplitButton controls I checked so far seem to lack in one way or another. Please add a SplitButton control that looks and acts like a standard control. It should both allow to act like a button (clicking on main body and dropdown arrow open a dropdown) and like an actual split button, where clicking on the main body executes a command and clicking on the arrow opens a dropdown button.

                                  • Completely rework the RichTextBox control (make it fast, extensible, capable of handling large text)

                                    - fast to initialize and load
                                    - stellar performance (this is the most important part)
                                    - able to handle large amounts of rich-text
                                    - provide an auto-size feature
                                    - better support for spell checking
                                    - either add support for image editing, bullet points and tables or make it extensible so we can implement it ourselves

                                    I imagine a lot can be taken from the VS2010 editor or AvalonEdit.

                                      • Allow loading custom dictionaries from memory or reuse already loaded ones

                                        Currently, if I have multiple controls on screen, that require spelling check with custom dictionary, each of those controls load the dictionary from disk - so having 10 controls on screen might end up as 5-10 seconds of loading.
                                        There are several problems:
                                        - Adding custom dictionary is not asynchronous operation, so you can't make it happen in background
                                        - Even if you use pack uri to load dictionary from assembly resources, it still accesses the disk - not only for reading, but also for writing temp file
                                        - It needs not only load custom dictionary, but also parse it …
