  1. Better support for cross assembly embedded fonts

    It has become my practice to embed all of my fonts in a single assembly and then referencing the fonts in that assembly from other assembly. This helps to reduce the redundantly embedded font when that font is used in multiple assemblies. It would be nice if the tools supported this as an option.

    • Fix compositecollection's lack of DataContext

      this StackOverflow post explains it all:

      http://stackoverflow.com/a/6446923/643085

      Basically, the CompositeCollection is a pain to work with due to it's lack of DataContext and the inability to use ElementName bindings.

      Please provide a way to bind the CollectionContainer.Collection Property to, say a ViewModel (underlying DataContext of the UI element whose ItemsSource is assigned the CompositeCollection) or allow the usage of ElementName binding for that:

      The following XAML snippet doesn't work in WPF 4.5:

      <ContextMenu>
      <ContextMenu.ItemsSource>
      <CompositeCollection x:Key="CompositeCollection">
      <CollectionContainer Collection="{Binding MyViewModelCollection}"/>
      </CompositeCollection>
      </ContextMenu.ItemsSource>
      </ContextMenu>

      Ideally, I'd expect that the CollectionContainer would be able to bind against the ContextMenu's DataContext somehow.

        • Restrict Behavior visibility

          When I define a System.Windows.Interactivity.Behavior<T> for e.g. an ItemsControl, like

          public class SomeAwesomaticBehavior : Behavior<ItemsControl>
          {
          }

          it will appear in Visual Studio's XAML editor (and probably in the Designer too) even for ordinary, non-Items-Controls and throw nasty runtime exceptions. This is contrary to Attached Properties which will appear only for intended types.

          The designer and the XAML editor must be updated to respect a behavior's scope. Because it surely does confuse co-workers and designer folks when a lot of Behaviors pop up that don't have anything to do with the current object.

          • Complete the Support for WPF Serialzation in System.Xaml namespace

            The XamlObjectReader will throw defered load exceptions for WPF schema. This apparently is because the Save method on the System.Windows.TemplateContentLoader was not implemented.

            Failing this please make Visual Studio or Blends object Serialization source publicly available.

            Even better do both.

            In any case custom applications that may want to do designer or transformations on XAML would greatly benefit by this, and it appears it just wasn't completed.

            Thank you.

            • Make it client/server

              Make only the UI-related code working on the client; something similar to www.canoo.com (RIA Suite)

              • Fix XPS Document Writer Threadsafety

                If you try to submit an .xps document to "Microsoft XPS Document Writer" printer using PrintQueue.AddJob(), but from a worker thread (not the application thread), it fails with an exception. I don't understand how that is even possible, but it's irritating to have to special case this one driver to print on the main app thread.

                • Provide way for ICommands to determine the UIElement which owns the command

                  ICommands should have the ability, when executed, to determine which UIElement owns the command. Perhaps when event handlers are invoked, CallContext could be used to store the current UIElement 'sender'.

                    • High use of controls or triggers made application flickered

                      When we use layout controls at high end and triggers, due to client requirement we create own style for specific control made wpf application flickered sometime... which is not good interface for client.

                      • Promote it better, it is a great technology with so much to offer. If it needs to be replaced by WinRt, then WinRt should do desktop too

                        Please improve the appearance of consistency and stability in your technology stacks... Please back your great ideas...

                          • Virtualization of Variable-Height Views/Data

                            Optionally support fixed width, and a variety of algorithms for calculating scrollbar parameters. (e.g. Query the entire collection for item dimensions up front, optionally cache views, etc.)
                            Support table, list, and tree scenarios.

                            An example of where this would be useful, is an email client that showed the full content of messages (thus variable height) in the right hand pane.
                            In our case, we have a list of hundreds of types of forms each with different and often variable height. We hacked together a virtualization solution that tworks, but something more polished could work better.

                              1) I'm looking at a design capability for Flowdocument. At present if we need to use VS 2010 for designing XPS document, then unfortunately we will have to place in in Windows XAML within a FlowDocument Scroll Viewer(or equivalent document readers). The Vs 2010 as such does not support FlowDocument as a root in XAML designer

                              2) Another important issue is about getting the header and footer in the document. At present we will have to use pagination Wrapper that inherits from DocumentPagination class and do it manually. Can there by much eaiser means to achieve the same.

                              3) The…

                              • Let me override the default value for DatePicker.FirstDayOfWeek

                                With most other dependency properties I can override the default value in my App.OnStartup method using OverrideMetadata. However, DatePicker assigns a default value to FirstDayOfWeek in the instance constructor, so the dependency property's default value is never used.

                                • TabItem.ToolTip should only affect the Header, not the content.

                                  When you set TabItem.ToolTip, the tooltip is visible in the entire tab along its content.
                                  This should be fixed, and the tooltip should be visible for the header only which makes much more sense.

                                  • Easier control template customization

                                    In many cases a simple change to the appearance of a control requires the wholesale replacement of the control template. It seems like there needs to be a more granular method to customizing the control without having to copy and edit the entire control template. It is not always clear what parts of a control template the control depends on such that replacing the template leads to subtle bugs in the controls behavior or display.

                                    • Multiple Code behind Partial Classes

                                      When creating partial classes for a XAML code behind class have the partial classes all reside under the XAML file in the solution explorer. Right now when you add a XAML file to a project 1 partial class (code behind) is nested in a node underneath the XAML file. If I add a new partial class for the code behind to hold event handlers it is in the solution explorer on its own. It would be nice if it would nest in a 2nd node underneath the XAML file.

                                      • Add [ContentProperty("Value")] attribute to the Setter class

                                        It's a pain to have to write <Setter.Value> every time the value cannot be written as an attribute (e.g. templates)...It should be obvious that the content of the <Setter> element is its value.

                                        • Datagrid mode to allow cell data (full/part) selection for clipboard copy not in edit mode.

                                          When displaying data in a datagrid, we need an option to land in a cell, mark the text within the cell and be able to copy it, without having to be in any edit mode to do so. The selection mode should be able to remain row selection, we need to be able to deal with selecting data inside the cell independently from the row/multi cell selection options.
                                          This option also needs to be available on textboxes in general, so that a read only user can copy appearance data out of fields to the clipboard.
