Field not Found

[Tobias]

I'm getting an error right away when using RadGanttView, the error is as follows:

Field not found: 'Telerik.Windows.Controls.Scheduling.DragAndDropSettings.DefaultDataConverter'

It looks to me like an reference issue, but I just can't figure out what I'm doing wrong. I'm already using RadChartesianChart and RadPieChart 

This is my code:

Hello Tobias,

Thank you for contacting us.

We are not sure what exactly is the cause of the issue that you are experiencing. Could you give us more details about the observed issue:

• Is this issue an exception that crashes the application or it is observed as a non critical exception
• Which version of the Telerik assemblies are you using the XAML or the No.XAML assemblies
• Are there any customizations applied to the Styles/Templates of the RadGanttView control or any other Telerik control

I created and attached a sample project which shows how the RadGanttView control could be declared. Could you try to reproduce the issue in that sample project and let us know what are the required steps. Looking forward to your response.

Regards,
Vladi

I know this is an old post. But i have just encountered the same problem. My problem was after upgrade the solution from .Net Framework 4.0 to .Net Framework 4.5, i didn't upgrade the telerik reference. They still refer to 2018.3.xxx.40 dll. Once i upgrade to 2018.3.xxx.45, the error disappeared.

Hi Joel,

I have double test the project from my colleague Vladimir with the latest version of our controls and haven't got any errors. Can you confirm that this error appears on your side using the same project? May I ask you to share some additional information about your set up. Which version of VS are you using? What is the OS of the machine which you are working on? If this project does not reproduce this error, can you modify it to mimic your application set-up so this error appears and send it to me for further investigation?

Hi Dinko,

  Don't worry about it. It is on my side.The solution was re-targeted from framework 4.0 to 4.5. I am putting up a post here to remind myself (and perhaps others) what needs to be done in case the same error shows up again in the future.
