Name/add a DataGrid column at run time

Hi all.
I was trying to rename a column in a datagrid so I could pull data from different tables but use the same form/datagrid for it.
the only way that I could find to do this was at this link:

http://www.c-sharpcorner.com/Code/2003/Feb/DynamicDataGrid.asp

It describes how to add columns via code at run time... and also some other things.

In short the way to add a column is
// Create ID column & add to DataGrid
BoundColumn col = new BoundColumn();
col.HeaderText="User ID";
col.DataField="ID";
DataGrid1.Columns.Add(col);

Hope this helps answer some questions.
