To reproduce: You must use Windows Server 2008. Add a RadTreeView set its theme to Windows8 and drag a node. Exception occurs in rare cases and is hardly reproducible.

To reproduce:
-add RadRibbonBar with RadDropDownButtonElement and use the following code:
 this.radDropDownButtonElement1.AutoToolTip = true;
 this.radDropDownButtonElement1.ToolTipText = "tooltip";

As a result, no tool tip has been shown.

Workaround:
public Form1()
{
    InitializeComponent();

    this.radRibbonBar1.ToolTipTextNeeded += radRibbonBar1_ToolTipTextNeeded;
    this.radDropDownButtonElement1.ToolTipText = "tooltip";
}


private void radRibbonBar1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
    ActionButtonElement actionButton = sender as ActionButtonElement;
    RadArrowButtonElement arrowButton = sender as RadArrowButtonElement;

    if (actionButton != null)
    {
        e.ToolTipText = ((RadDropDownButtonElement)actionButton.Parent.Parent).ToolTipText;
    }
    else if (arrowButton!=null)
    {
        e.ToolTipText = ((RadDropDownButtonElement)arrowButton.Parent.Parent).ToolTipText;
    }
}

To reproduce:
- Apply the VisualStudio2012Light theme to a RadForm (use 2013.3.1016 version of the assemblies).

Workaround:
- Open the Theme in Visual Style Builder.
- Select RadForm in Control Structure window.
- Expand up to TitleBar and select it.
- Apply the TitleBarBorder from the repository to the TitleBorder element.

Add image editor.

For the time being one can use the WPF component with ElementHost: http://www.telerik.com/help/wpf/radimageeditor-overview.html

FIX. RadRibbonForm - exception when loading icon in design time "Requested range extends past the end of the array."

DECLINED: not an issue

To reproduce:
-add RadCommandBar with CommandBarDropDownButton;
-change its arrow direction:
this.commandBarDropDownButton1.ArrowPart.Arrow.Direction = Telerik.WinControls.ArrowDirection.Right;    

As a result there is one arrow to the right (correct) and another arrow image to the down direction (incorrect).

Workaround:
    private void Form1_Load(object sender, EventArgs e)
{
    this.commandBarDropDownButton1.ArrowPart.Image = null;
}

To reproduce:
-use RadForm with WindowState=Maximized at design-time;
-add RadPanel with Dock = Top;
-after running the application minimize the form and maximize it again; as a result the form title bar is cut off.

Workaround: set Margin of the FormElement and Top docked panel when maximizing:

private void Form1_SizeChanged(object sender, EventArgs e)
{
    RadForm form = sender as RadForm;
    if (form != null)
    {
        if (form.WindowState == FormWindowState.Maximized)
        {
            form.FormElement.Margin = new Padding(0, 8, 0, 0);
            (form.Controls[0] as RadPanel).PanelElement.Margin = new Padding(0, 20, 0, 0);
        }
    }
}

To reproduce:
-add RadPivotGrid
-apply Breeze theme; all filter buttons are missing for the column descriptors;

To reproduce:
- Create new RadDropDownMenu wit some items in it.
- Set ShowItemToolTips to true.
- Subscribe to ToolTipTextNeeded event.
- Notice that despite the event is fired the tooltips are not shown.

To reproduce:
Open Demo Application, open editors, open Time Picker Exception should occur.
Note:
The exception occurs if the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\TimeZoneKeyName is missing from the registries.

Workaround:
Restore the registry file as per this MSDN article - http://support.microsoft.com/kb/555537

PrintSettings dialog crash if Printer's SourceName is empty.
Workarround: Enumerate printers and set a name for empty Source Names.

class MyPrintSettingDialog : PrintSettingsDialog
{
    public MyPrintSettingDialog(RadPrintDocument document):base(document)
    { }
    public MyPrintSettingDialog():base()
    { }
 
    protected override void LoadSettings()
    {
        PrinterSettings.PaperSourceCollection paperSourceCollection = this.PrintDocument.PrinterSettings.PaperSources;
        int index = 0;
        while (index < paperSourceCollection.Count)
        {
            if (string.IsNullOrEmpty(paperSourceCollection[index].SourceName) || paperSourceCollection[index].SourceName == "-1")
            {
                paperSourceCollection[index].SourceName = "NONEMPTY NAME";                    
            }
             
            index++;
        }
 
        base.LoadSettings();
    }
}

Add heatmap control as in the WPF suite http://www.telerik.com/products/wpf/heatmap.aspx

The NavigateBackwards/Forwards buttons in RadSchedulerNavigator should show image instead of text when using Aqua theme.

WindowForms - the source code(RadControlsVS2010) does not build in Debug40 configuration.

If the list of shortcuts contains a null value exception occurs.

CodedUI playback does not able to recognize a button placed in RibbonBar ButtonGroup/Group

To reproduce:
- add a grid with some sample rows
- apply TelerikMetro theme to the grid
- select the rightmost column
- you will notice that there is 1px extra space between the grid border and the column

Workaround:
- Open the TelerikMetro theme in Visual Style Builder.
- Expand RadGridView up to GridTableElement.
- In the elements window expand TableElement
- Set the padding property to 0.

Change the gestures logic so it can be enabled/disabled per-control.

see Control1.SupportsGestures property

Expose the SupportsGesture property in the GestureInfoHelper class to enable users to enable/disable gesture support manually.
Workaround:
set the field with Reflection
private void DisableGestures()
        {
            Type gestureHelperType = typeof(GestureInfoHelper);
            FieldInfo field = gestureHelperType.GetField("supportsGestures", BindingFlags.NonPublic | BindingFlags.Static);
            field.SetValue(null,false);
        }

Description: iterate through all the Telerik controls in an application and set a theme to each RadControl at design-time. 

Resolition: Set the RadForm or RadRibbonForm ThemeName, Then right click on it and press "Apply current form's theme to controls." menu
