Hi,

Version : 2010 Q2 - 2010.2.714.35

Hi,

I have a WPF application (.net 3.5) with MVP pattern and the Microsoft Unity container.
When i add a RadDatePicker in a view, there is a drop down problem :
the calendar doesn't appear and other controls have a similar behavior : for the original ComboBox, the drop down list don't display.
Without RadDatePicker, all controls appear correctly.
(With the version 2010.1.422.35, it work.)

I don't have this problem in a classic WPF application (without MVP neither Unity).

Otherwise, in the Visual Studio out, an error occurs many time  :

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=PART_DropDownButton'. BindingExpression:Path=IsMouseOver; DataItem=null; target element is 'ButtonChrome' (Name='ButtonChrome'); target property is 'RenderMouseOver' (type 'Boolean')

I try to catch this error with a diagnostic converter (System.Diagnostics) :
<Style TargetType="{x:Type telerik:RadDatePicker}">
 <Setter Property="???" Value="{Binding Path=???, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}, diagnostics:PresentationTraceSources.TraceLevel=High}"/>
</Style>

But i don't found interesting property to watch in order to have more details.

Thanks in advance

Hello FRANCOIS,

The exception you are getting seams pretty strange. The pointed binding error has been already resolved and will be included in the nearest internal build. It was due to a misspelling error in one of the template control part. We will kindly appreciate If it is possible for you to prepare a small app with the RadDateTimePicker issue.
