Your code mostly looks like OK. But I am suspecting that you only problem with textBox ID. Just cross it and see what is the exact ID of textbox. Use below code what are controls present inside panel:
foreach (Control obj in Panel1.Controls)
{
    if (obj is Textbox) {
        // do something with textbox
     } else if (obj is Checkbox) {
        /// do something with checkbox
     }
}
