How to reference DataGridViewColumn.HeaderText manually in resources files?

For transaction purposes, I created resources files which replace text property of my winforms components.

However, it seems i can't correctly reference my DataGridViewColumn.HeaderText property manually in the resources file; but I can change the HeaderText property of it in the code, but not in the resource file (it works for other components...)

I've also tried :

DataGridViewColumn.HeaderText = "test1";
DataGridViewColumn.HeaderCell.Value = "test2";
DataGridView.Columns[1].HeaderText = "test3";

The code works when calling it but not when I put it in the resources file.
