After Upgrade from 4.7 (trial version) to 6.3 (Paid Version) getting Server Error in Controllers

Title:

BI{code} ?

After upgrading to *6.3 which is Paid version* , we are getting errors for the methods (Server Side). GroupView and SelectableItem are not working and throws server error as below. Error CS0411 The type arguments for method 'GridExcelBuilder.BuildGroup<T>(ISheet, string[], ref int, GroupView<T>)' cannot be inferred from the usage. Try specifying the type arguments explicitly. Error CS0308 The non-generic type 'GroupView' cannot be used with type arguments Error CS0246 The type or namespace name 'SelectableItem' could not be found (are you missing a using directive or an assembly reference?)

  please have a look here: https://www.aspnetawesome.com/learn/mvc/CommonProblems#Problems-when-upgrading-to-a-newer-version regarding `GridExcelBuilder`, it is not part of the library, you can copy the newer one from our main demo source code.

  • ok, in the link mentioned in the answer you can read "For each new version in the release notes we have instructions on how to migrate your version from ..." and here: https://www.aspnetawesome.com/learn/release/Version5#Migrating-from-previous-versions you can read "replace usages of SelectableItem with KeyContent" you simply need to read and follow the instructions
