Hanging the UI for bigger xaps.

Add support for opening media files from client's local machines. At the moment an exception is thrown.

Due to the radically decreased interest in Silverlight the XAML team decided to considerably reduce the efforts invested in any new features or new components in the UI for Silverlight offering. Hence this request will not be addressed and is marked as declined.

Not measured correctly when no width/height is specified.

When the PngBitmapEncoder uses source from a PNG file with opacity then the result image rendering is gray. The class is available in UI for Silverlight.

Extend the WP7 support. Add support for each assembly and control.

Pressing Space key when typing in TextBox in Expander's Header expands the control.

The root cause is not located in the RadExpander control. If using Microsoft ToggleButton with TextBox inside the space key will trigger a button click. This issue is for Silverlight platform.
The same sample in WPF does not trigger a button click.

This issue is reproducible when you host the RadExpander in a ControlTemlate targeting the native ListBoxItem.

DECLINED: XAML Team reviewed this item and taking into account the current state of SIlverlight platform decided not to address it in the future. 

RadRichTextBox`s dlls cannot be minified ( Telerik.Windows.Documents and its derivative dlls)

This issue occurs when the ApplicationMenu is bound. The button in the ItemTemplate of the ApplicationMenu could be both RadSplitButton and RadDropDownButton. Their DropDownContent should not be displayed downwards, it should be displayed in the RightPane ( the Content of the Applicationmenu)

Declined: When the ApplicationMenu is in DataBound scenario the ItemsControl from which the ApplicationMenu inherits automatically creates ContentPresenters for each item and wraps their content. As the ApplicationMenu knows how to manage RadRibbonDropDown/Split buttons you will need to provide one of these containers as direct child of the  menu. You can achieve that using the following code, to show all items as RadRibbonDropDownButton:

public class CustomApplicationMenu : ApplicationMenu
    {
        protected override bool IsItemItsOwnContainerOverride(object item)
        {
            return false;
        }

        protected override DependencyObject GetContainerForItemOverride()
        {
            return new RadRibbonDropDownButton();
        }
    }

We have a RadBook control with Left and Right PageTemplates defined.
In both templates, there is some content defined along with a RadBusyIndicator used to display a loading message during the load of the actual controls in the template.
The problem is, that the RadBusyIndicator instances are not released from the memory and it seems that they even prevent the actual controls to be garbage collected.

Workaround:
The issue is caused by a limitation of the Silverlight framework and the Telerik Window8 theme in which in order for the the progress bar animation to be smooth additional  EaseIn has been set to its KeyFrames. In order to resolve this issue all you need to do is remove the EaseIn from the Indeterminate VisualState of the Style which targets RadProgressBar. You can find attached a sample project which shows the described workaround.

Sometimes the application never loads the requested dlls' content.

RadDataForm-IsReadOnly state of a TextBox is not persisted when switching implicit styles

Support PRISM / MEF in Xap minifier.

ElementName binding is not working in RadRibbonBackstage.

Reason for closing: The ElementName binding in Adorner is not supported and as the RadRibbonBackstage is Adorner it is not working there as well. Due to that framework limitation we cannot fix this issue and we will change the status of the feed back item to declined. You can find more information about the Adorner and its limitation in this article ( http://msdn.microsoft.com/en-us/library/ms743737%28v=vs.110%29.aspx ).

The KeyUp/KeyDown events sometimes are not triggered when using Keyboard.Modifiers. The issue can be reproduces if the keyboard key combination is pressed quickly.

Useful case where using those modifiers is when the desired behavior is to restrict the Ctrl+Z (undo command) in the RadWatermarkTextBox control.

If you define 700 columns, then the horizontal lines are missing:
for (int i = 0; i < 700; i++)
{
      var nameCol = new GridViewDataColumn() { DataMemberBinding = new Binding("Name") };
      this.radTreeListView.Columns.Add(nameCol);
}

After selection autocomplete uses the data within TextSearchPath for display. We search many fields so this output is less than ideal. DisplayMemberPath or a SelectedItemTemplate would be better.

Change the version of the assemblies so the Visual Studio start diferentiate them from the original
