If the height of RadComboBox is set to a value smaller than 26px (in Office2013) then the content of the RadToggleButton presenting the selected content is clipped.
This was reproduced with the Office2013 theme.
To work this around set the MinHeight of the child RadToggleButton to the same MinHeight as RadComboBox.
It might also be nice to take it one step further and give the option to choose the key that fires an update off

When the CheckBox is focused the issue is appearing. Available in LIB version 2016.2.905, it will be also available in the 2016 R3 Release.
The same issue can be observe when placing the control inside ToolBar.
When you click on the TextBox of an editable RadComboBox all the text should be selected, but it is not, even when SelectAllTextEvent="All" is set. The text is blinking as selected for half a second and then deselects.
When filtering is enabled, enter text that doesn't exist in the items and when the focus is removed the text entered is deleted, but it should stay. The solution of this issue was implemented by a new feature in the control which determines if the Text of the RadComboBox should be updated on LostFocus or not. Simply set the UpdateTextOnLostFocus dependency property of the control to "False". By default its value is True and no change in behavior should be observed. The UpdateTextOnLostFocus dependency property is available in the 2015 Q2 SP1 release.
Place a RadComboBox control in a RadPane. Make it floating and dock it again. When selection is changed, the SelectionChanged event is fired multiple times.
