Hi,
As per I can see, you are adding the textboxes like this:
TextBox tb = new TextBox();
tb.ID = "txtBox1" + i.ToString();
cell.Controls.Add(tb);
row.Cells.Add(cell);
Very easy to get the values. Just write the following code:
for (int i = 0; i < 10; i++)
{
TextBox tb = (TextBox)form1.FindControl(("txtBox1" + i.ToString()));
string value = tb.Text;
}
All the best.
