I just updated to Q3 2011 SP1 so that I can get more document support for PDF viewer. After the installation and the upgrade wizard in VS2010, I have now reference to assemblies of version: 2011.3.1220.1040
When I run the project, it runs fine, expect that when I click on the button to open to PDFViewer in ChildWIndow, it crashes and gives error that says that I have a InvalidCastException.
Please see attached.
- Basically it says that it cannot convert "System.Windows.Controls.ComboBox" to type "Telerik.Windows.Controls.RadComboBox".
- I do not have any ComboBoxes in the childwindow. Just the PDFViewer inside a border.
Any help is appreciated.
