Cannot edit GroupingControl properties in design mode. All changes are failed:
Code generation for property ''VisibleColumns'' failed. Error was: ''''GridVisibleColumnDescriptorTypeConverter'' is unable to convert ''Syncfusion.Windows.Forms.Grid.Grouping.GridVisibleColumnDescriptor'' to ''System.ComponentModel.Design.Serialization.InstanceDescriptor''.''
How to solve ? Using 18.104.22.168 version and Framework NET 1.1.
What is the language of the operating system you are using? For example, currently BrushInfo serializing seems to fail on German XP. Maybe this problem is something similar.
We could not see this in our EmployeeView and CategoryView samples. Can you?
Can you post a sample project showing the problem?
