On a windows form I've added a table layout panel (TableLayoutPanel1). On its 1st row i've added two text boxes and these text boxes are added into next rows of TableLayoutPanel1 automatically on button click. In runtime i've added 4 rows, now i want to update data from those text boxes into sql database by another button click. I'm using visual basic (visual studio 2010) and Sql Srver 2008.
