RadCombobox IsEditable System.Reflection.TargetInvocationException

[Yanet]

Hello,

   After updated  the Telerik dll I am not able to use the IsEnable property of the RadComoboBox (using silverlight 4)

   I want to alllow the user to type in the combobox if the desired option is not available in the list. This was working fine untill I updated the dlls to version 2009.3.1314.1030. Now when I add in my XAML the IsEditable property I have a build error which says

System.Reflection.TargetInvocationException

Exception has been thrown by the target of an invocation.

Is this propety not longer available? Any idea about this issue? Any idea about how to implement an editable combobox in Silverlight 4?

Thanks,

Hello Yanet,

We are not aware of any TargetInvocationException issue concerning the IsEditable ComboBox control.

Could you share with us the version from and to which you have upgraded and more details on how you are setting the IsEditable property in your project. Some code snippets would be very helpful.

It is worth mentioning that since our Q3 2012 we have discontinued supporting RadControls for Silverlight 4 and RadControls for WPF 3.5. You can read this blog post on this topic.

Hi Vladi,

   Thank you very much for your response. Before, I was using a trial version 2011.2.712.1040 which was updated to a non trial version 2009.3.1314.1030.

    Here is a piece of code of my XAML. In Italic you will see my radcombobox. As soon I add the IsEnabled="True" and build the project, the XAML code is underlined in blue (build compilation error) and in the desig section I got the System.Reflection.TargetInvocationException message. As soon as I remove the IsEnabled property, everithing works fine.

     Thank you for share the blog post regarding the RadControls and Silverlight4. I really like RadControls but I guess I will change it as it is not supported for Silverlight4. 
   
      Let me know if you need additional information.

Yanet

Hi Yanet,

It looks that you are going backwards in the versions of the controls and it is expected that some feature which are working in the newer versions wont work in the older versions of RadControls, also note that the  2009.3.1314.1030 version of RadControls is for Silverlight 3 not for Silverlight 4.

Since we no longer support Silverlight 4 and Silverlight 3 we will not be able to provide you with a fix for any issues in those platforms.
