To reproduce:

 public Form2() { InitializeComponent(); MyControl c = new MyControl(); c.Dock = DockStyle.Fill; this.Controls.Add(c); }

public class MyControl : RadControl
{
    protected override void CreateChildItems(RadElement parent)
    {
        base.CreateChildItems(parent);
        LightVisualElement element = new LightVisualElement();
        element.Text = "Hello" + "\t" + "World";
        element.StretchHorizontally = true;
        element.StretchVertically = true;
        parent.Children.Add(element);
    }
}

Workaround: 

   public partial class Form2 : Form

    {
        public Form2()
        {
            InitializeComponent();
            MyControl c = new MyControl();
            c.Dock = DockStyle.Fill;
            this.Controls.Add(c);
        }

FIX. RadBreadCrumb's ThemeName drop down does not display TelerikMetroTheme, when the latter is added to the form. However, if you type in the theme name, it is correctly applied.

Note: the same problem is noticed for VisualStudio2012Dark theme as well. 

Workaround: set the theme at run time by using the ThemeName property.

FIX. MSAA - TestManager cannot find RadDateTimePicker
Approved

To reproduce:

Add an mdi child to a form:

this.IsMdiContainer = true;
new Form
{
    MdiParent = this
}.Show();

ThemeResolutionService.ApplicationThemeName = new VisualStudio2012DarkTheme().ThemeName;

Start the application and maximize the child form. You will see that there is no status bar for the child form. The same behavior occurs with the VisualStudio2012LightTheme.

Workaround:

You need to set images to the buttons in the title bar:

this.FormElement.MdiControlStrip.MinimizeButton.Image = this.FormElement.TitleBar.MinimizeButton.Image;
this.FormElement.MdiControlStrip.MaximizeButton.Image = this.FormElement.TitleBar.MaximizeButton.Image;
this.FormElement.MdiControlStrip.CloseButton.Image = this.FormElement.TitleBar.CloseButton.Image;


this.FormElement.MdiControlStrip.MinimizeButton.ShowBorder = this.FormElement.MdiControlStrip.MaximizeButton.ShowBorder = this.FormElement.MdiControlStrip.CloseButton.ShowBorder = false;

How to reproduce: check the attached project and compare the font size of the two labels. Also when the form is moved from a screen with HDPI to a standard screen with DPI=96 the font does change.

To reproduce: 
1. Use the following code snippet:
public class ViewModel:INotifyPropertyChanged
{
    public ViewModel()
    {
    }

    private bool _isShown;

    public bool IsShown
    {
        get
        {
            return this._isShown;
        }
        set
        {
            this._isShown = value;
            OnPropertyChanged("IsShown");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs(propertyName));
    }
}

2. Add a MS Panel and a RadPanel to the form.
3. Add Panel.DataBindings at design time for its Visible property to the ViewModel.IsShown property.
4. When you run the application, the MS Panel is not visible. However, if you remove the RadPanel it is shown. Please refer to the attached sample video illustrtaing better the performed steps.

To reproduce: add a RadButtonElement to the a RadRibbonBar group. Set its Text property to "<html>html formatted text" and the Enabled property to false. By default, its UseCompatibleTextRendering property is set to true, but the text is rendered blurred. Please see the attached file.

To reproduce add RadGroupBoxElement in another control (for example in a ribbon group) and use the VisualStudio2012 theme.

Workaround: either open the theme and set the GroupBoxElement theming to be reused in other controls or use the following snippet to do the same:
 private void FixTheme()
        {
            string controlType = "Telerik.WinControls.UI.RadGroupBox";
            StyleGroup styleGroup = ThemeResolutionService.GetTheme("VisualStudio2012Light").FindStyleGroup(controlType);
            styleGroup.Registrations.Add(new StyleRegistration("ElementTypeDefault", "Telerik.WinControls.UI.RadGroupBoxElement", controlType, string.Empty, string.Empty));
        }

After revamping the documentation for the Telerik UI for WinForms product, the following problems occurred:

1. Search for a specific class or method in the search box in the following site: https://docs.telerik.com/devtools/winforms/introduction. Select one of the results referring to the API documentation. As a result you will be navigated to the main page of the API reference instead of to the respective class or method. Refer to the Problem1.gif file. It seems that the search results from the API reference return old links for the previous API link pattern.

2. The search box in https://docs.telerik.com/devtools/winforms/api/ is significantly lagging while typing. We should consider performing the search operation after pressing Enter and not with each keystroke. Please refer to the Problem2.gif file.

3.  When you scroll the navigation view on the left side to a certain position and select an article, the vertical scrollbar sometimes gets reset to the top position and you have to scroll back.  (Note that this problem is not reproduced each time).
