You refer to this one, I guess:


But in this demo you are showing all the columns and than you can remove columns or add. What if you set the grid without the column field e.g. “GDP_Total” first and then add this column later. All the cells for this added column are empty (but the data is already loaded in the data source)

And as I mentioned above there is also this strange line : grid.Columns = new List<GridColumn>() { }; //TODO: remove
