As of UI for Blazor 4.0. ExcelExportableColumn is inaccessible due to its protection level and GridExcelExportColumn should be used instead.
I am trying to add the hidden columns to the exported file through the OnBeforeExport event. However, I am unable to create an exportable column instance using the GridExcelExportColumn. I get the following error:
CS1729: GridExcelExportColumn does not contain a constructor that takes 0 arguments.
