Hi,
I've set up a RadScheduleView according to that of the sample project in the RadScheduleView documentation (ScheduleView_EF_SL). When I run the application, the InitializeComponent() method in the constructor of the Usercontrol that contains the RadScheduleView throws the following exception.
XamlParseException
-> InnerException: InvalidCastException
-> Message: Unable to cast object of type 'Telerik.Windows.Controls.WeekViewDefinition' to type
'Telerik.Windows.Controls.ViewDefinitionBase'.
I am able to compile and run the sample project from the documentation. I've compared that project and my own, but I haven't been able to figure out what the problem is. This is the ScheduleView XAML:
And here is the code:
I'm using RadControls for Silverlight 4 2011.3.1116.1040, VS2010, and I'm running on Windows 7 Home Premium x64.
Much appreciated,
Aaron

Hello Aaron,
Most probably you have references to both Scheduler and ScheduleView assemblies. They both contain classes that are named DayViewDefinition, WeekViewDefinition, etc. hence the name collision in XAML. If you remove the Telerik.Windows.Controls.Scheduler.dll from your references the problem should disappear.
Kind regards,

I'm using a combination of Expression Blend 4 and Visual Studio 2010. I get an unable to cast object of type 'Telerick.Windows.Controls.DayViewDefinition' to type 'Telerik.Windows.Controls.ViewDefinitionBase'.
I do not have a reference to Telerik.Windows.Controls.Schedule. I am using version 2011.3.1220.1040 (Trial version) of ScheduleView.
Please find my xaml below:

Hi,
The only reason for the occurrence of the "Unable to cast object of type 'Telerick.Windows.Controls.DayViewDefinition' to type 'Telerik.Windows.Controls.ViewDefinitionBase'" exception that we are aware of is referencing both Telerik.Windows.Controls.Scheduler and Telerik.Windows.Controls.ScheduleView assemblies in the application. To confirm this is not the case, could you please, prepare and send us a simple application that could be used to observe the problem and we will immediately respond with a solution.

Is this still the case? We are using the scheduler assembly for one aspect of an application and would like to use the schedule view for a type of dashboard. If it is not possible to use both within a project, what would be a good alternative since the RadChart does not support timeline type of functionality.

Hello Michael,
To resolve conflict between namespaces you can use aliases. Please follow the link below for more details:

OK perhaps you did not read this thread? This was about the conflict within XAML and being able to use the ScheduleView control while still having the Scheduler assembly reference; this had nothing to do with setting up code from code behind.

Hello Michael,
You are right, I am sorry for my misunderstanding.
At the moment we are not aware of an easy way to have both controls referenced in the same project. Our recommendation is to replace completely the Scheduler with RadScheduleView. Please note that since Q1 2012 RadScheduler is removed from the installation and you will not be able to upgrade.
