So the DataGridView is not adding rows?
What code are you using to update the DataGridView?

That will really depend on how you have your text data arranged.
If you just have a single text box with values in it, and you want to convert that to a DataGridView (with a button push), you could do something like this:
private void button1_Click(object sender, EventArgs e)
{
dataGridView1.DataSource =
(
from arr_str in textBox1.Text.ToString().Split("\r\n".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)
select new
{
Converted = arr_str.Trim()
}
).ToList();

Are you looping through the values in the text box?

Do you need to re "new" your SqlCommandBuilder after the Fill()?

I don't use DataSet and it's associated classes.
Is it possible for you to simplify this by eliminating the use of the data rows, tables and adapters and just issue the SQL directly for the insert?
[after you fix the problem...]
The data is pulled out of the controls twice -- once for the DataGridView and then again for the DataRow in the insert() method. Is it possible to make one function that does the select, one that does the insert, one that does the update but where NONE involve the display?
That way you can just pass the data to and from the functions without having to deal with the visual at the same time.
Once the data is processed, you can update the display.
