Intellisense says IsDropDownOpen is available, but if I add it I get Invalid XAML error in Blend and parser error when I run the app.
Whats the property to open the dropdown?

Hello,
The IsDropDownOpen property is the right way to open RadComboBox. I suspect that the problem is related to a missing reference, most probably the Telerik.Windows.Controls.dll assembly, since Blend does not add automatically all needed references.
The application has all needed references. As I said if I add the property I get Invalid XML in blend and a PARSER error when I run the app. If I remove the property everything works fine.
This project has Telerik.Windows.Controls, Telerik.Windows.Controls.Input, Telerik.Window.Data.

Hi,
I apologize for the misunderstanding. I created a simple test application and I was able to reproduce the problem. It is related to the fact that the IsDropDownOpen property changed event handler uses template parts that are not yet initialized if you set the property in XAML. Generally, it was not intended to be set this way, but I assume this behavior as a bug. It will be fixed in the next internal build, this friday.
