RadGridView Not Working When Attempting to Open Property Builder

[John]

I get Error invoking: 'Open Property Builder'.  Details: Object of type 'Telerik.WinControls.UI.TableViewDefinition' cannot be converted to type 'Telerik.Wincontrols.UI.IGridViewDefinition.

[John]

The Version is 2017.2.613

Hello John, 

Thank you for writing.  

I would like to ask you to carefully check the references to all Telerik controls in your project and make sure that they are the same version considering the suffix as well (.20 or .40). Better yet, you can remove all references and add them anew by using the DLLs from your fresh installation. Delete the license.licx file. After that, you should rebuild your project, close Visual Studio and open it again to make sure that no references are kept in the memory by Visual Studio.  

I hope this information helps. Should you have further questions I would be glad to help.

Regards,
Dess

I was getting this same issue with version 2019.2.618.40 and have fixed it with some of the information in this post. 

1) I ran the Upgrade Wizard in the Telerik UI for Winforms menu (even though the project was already upgraded).

2) Received a screen showing 0 errors, 0 everything. It basically seemed to do nothing.

3) Chose Build, Rebuild Solution and let that run.

4) Closed out of Visual Studio Professional 2017.

5) Restarted Visual Studio.

6) Opened the project and then I was able to "Open Property Builder" for any GridView.

Good solution. I also get the same issue - very occasionally - with Visual Studio 2022, and this fixes the issue. 

..but why?

Hello, Ian,  

There are cases in which after upgrading to a new Telerik version, the existing project still refers the old assemblies. If you identify any precise steps that always replicate any undesired behavior, please let us know. That is why we always recommend our customers to check the references after the upgrade process and if they don't match with the latest version, just replace the assemblies with the new ones:
