DataBoundGrid - How to add column at runtime ?

I have a DataBound grid with dynamically created columns.
I need to add a column at runtime, but it does not appear.
Could you please advise?
Thanks.

Here is my code:
GridBoundColumn newCol = GridConfigurationHelper.createColumn();
GridHierarchyLevel hl = _grid.Binder.GetHierarchyLevel(0);
hl.GridBoundColumns.Add(newCol);

_grid.Binder.InitializeColumns();
_grid.Model.ColWidths.ResizeToFit(GridRangeInfo.Table(), GridResizeToFitOptions.IncludeHeaders);

Hi Gen,

Please try this code snippet and let me know if this helps.

GridBoundColumn newCol = GridConfigurationHelper.createColumn();
GridHierarchyLevel hl = _grid.Binder.GetHierarchyLevel(0);
hl.InternalColumns.Add(newCol);
GridBoundColumnsCollection columns = hl.InternalColumns.Clone() as GridBoundColumnsCollection;
_grid.GridBoundColumns = columns;

Best regards,
