I have the dataset bound to textboxes on the form:

txtTitle.DataBindings.Add("Text", oDataSet, "ItemRow.Title");
txtCategory.DataBindings.Add("Text", oDataSet, "ItemRow.Category");
txtAuthor.DataBindings.Add("Text", oDataSet, "ItemRow.Author");
txtCatNo.DataBindings.Add("Text", oDataSet, "ItemRow.Catalogue_No");
txtIsbn.DataBindings.Add("Text", oDataSet, "ItemRow.Isbn");
txtPublisher.DataBindings.Add("Text", oDataSet, "ItemRow.Publisher");

In SaveChanges I then pass the oDataSet variable to this code in my Data Access class:

public bool UpdateDataSet(DataSet oDataSet, string sTableName)
{
	bool bRetVal = true;

	try
	{
		DataRow oRow = oDataSet.Tables[0].Rows[0];
		DataRowState state = oRow.RowState;                \\state = Unchanged

		oAdapter.Update(oDataSet, sTableName);
	}
	catch(SqlException e)
	{
		oException = e;
		bRetVal = false;
	}
	return bRetVal;
}

The DataAdapater is stored as oAdapter on the data access class. When I run this, it doesn't error, but it also doesn't save.

Anyone wanna set a newbie straight?
