I have a User Control that inherits from a DataGridView, it has a Sub that builds the columns for it called BuildColumns() inside the Sub New().

When i drag it on to the form in Design it builds the columns and i can remove or edit them in the Edit Columns or Columns Collection, but of course in Run Time they get overwritten by BuildColumns() being called again, i wondered how i could send back the Column Collection from design time to the User Control for Run Time?

What I have tried:

Booleans to to trigger when i edit columns but they don't work, probably missing something. No idea
