By field, do you mean a Label control?

You can do Label1.Text = "Hello World!";

Hi Zzdfc, in V1 of DynamicData the metadata is read only so after the initial load in the Global.asax you can't change it [:(]

However you could write you own Filed Generator based on IAutoFieldGenerator as in this example here: 

public class ColumnNameFieldsManager : IAutoFieldGenerator
{
	protected MetaTable _table;

	public ColumnNameFieldsManager(MetaTable table)
	{
		_table = table;
	}

	public ICollection GenerateFields(Control control)
	{
		List<DYNAMICFIELD> oFields = new List<DYNAMICFIELD>();

		foreach (MetaColumn column in _table.Columns)
		{

			// carry on the loop at the next column  
			// if scaffold table is set to false or DenyRead
			if (!column.Scaffold)
				continue;

			DynamicField f = new DynamicField();

			f.DataField = column.Name;
			// do your column name look up here
			f.HeaderText = "***" + column.Name + "***";
			oFields.Add(f);
		}
		return oFields;
	}
}

And here it is used on the Edit page:

protected void Page_Init(object sender, EventArgs e)
{
	DynamicDataManager1.RegisterControl(DetailsView1);
	// add ColumnNameFieldsManager to set column names
	table = DetailsDataSource.GetTable();
	DetailsView1.RowsGenerator = new ColumnNameFieldsManager(table);
}

Hope this helps [:D]
