Adding a new column and values into a dataset

Do
Hi,

I have a dataset that returns values.
I have done some calculation and

1) want to set the results into a label
that I have put into an itemtemplate in a datagrid.

2) Or just set the values to a new column in the existing dataset
and use that data for my datagrid

How do I go about doing this?

Hi,

1) add column :
DBColumn = New DataColumn()
DBColumn.ColumnName = "ItemValue"
DBColumn.DataType = System.Type.GetType("System.String")
DBTable.Columns.Add(DBColumn)

2) loop through rows and set new column data.
