            //txt_empresa.Text = Convert.ToString(arr.Rows[0][3]);

            //txt_estado_actual.DataBind();
        }    
    }
the first txt is in black and the last txt too. The others ones are ok (100 registers)

Simple. Maintain a counter of entries you have made. When you hit 100, move on to the next txt and start counting over again.

This is not how it works. You are supposed to do your tasks. If you have an error that you can not solve, you are welcome to ask that concrete issue and you will get an answer.
