There's no easy, straightforward way to do it, but it is do-able. Databinding doesn't really work that way, so you've got to kludge it a bit ... this will work:

1) Create 31 BindingSource objects.
2) Set the DataSource of each BindingSource object to your DataTable.
3) Set the Position of the first BindingSource object to 0, the second to 1, the third to 2, etc.
4) For each TextBox, set the DataBinding in the usual way:

   this.txtDay1.DataBindings.Add("Text", bs0, "TheData");
   this.txtDay2.DataBindings.Add("Text", bs1, "TheData");
   this.txtDay3.DataBindings.Add("Text", bs2, "TheData");

It might be more trouble than it's worth, unless you might use each of those 31 BindingSource objects for displaying some other data for each of those 31 rows.
