RadGridView design time error

[hDrummer]

Hi,

I have Microsoft VS Ent 2019 with latest patch and try to open Property Builder of RadGridView at design time, WinForm project.

Yesterday it worked and I created complex grid with groups on multiple columns. It consumed all of the day.

But today I can't continue my work,

Solution compiles OK. At run-time it seems to be all ok.

How can I fix this problem?

And to the point, could you, developers, make theborder of the Property Builder sizeable? It's too hard to work with such a small window.

Hello, Vitalii,    

I would like to ask you to 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) since it is usually the most common reason for such a behavior after upgrading. Better yet, you can remove all references and add them anew by using the DLLs from your fresh installation: https://docs.telerik.com/devtools/winforms/installation-and-upgrades/updating-assemblies-in-a-project 
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. Ensure that no old versions are available in GAC: https://docs.telerik.com/devtools/winforms/knowledge-base/examine-the-gac 

As to the Property Builder, feel free to submit a feature request in our feedback portal in case you need any improvements to the dialog:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hello,
In the long run I did find how to fix this problem. I decided to delete all references from xxx.Designer.cs of this form to SortDescriptor.
After that all works fine - now I can open Property Builder and continue my work.

Deleted lines:

Telerik.WinControls.Data.SortDescriptor sortDescriptor1 = new Telerik.WinControls.Data.SortDescriptor();
...
sortDescriptor1.Direction = System.ComponentModel.ListSortDirection.Descending;
sortDescriptor1.PropertyName = "xxx";
this.rdgvMNT.MasterTemplate.SortDescriptors.AddRange(new Telerik.WinControls.Data.SortDescriptor[] {sortDescriptor1});
