    Hi All I have two panel in my form, my 1st panel contains 3 buttons and the 2nd has 2 buttons, 3 textboxes and a label. I need to get all of these controls to save their settings into a file, I tried:

    foreach (Control ctrl in this.Controls)
    MyFile.ReadLine(ctrl.Text); // For example

    But "this" has only two controls (My two panels) and I can't see the other controls contained in panels. I know I can use the foreach statement for each of my panels but if I have a panel in panel2? Do you have any idea to solve this using only one loop? Regards.

    While (true) { Human.isLearnable = true; }

    Each Panel has a Controls property, no?

      You can use something like this:

      foreach (Form frm in Application.OpenForms)
      {
      foreach (Control ctrl in frm.Controls)
      MessageBox.Show(ctrl.Text);
      }

      This contains two foreach statement but indepedent of how many forms you have, you can get their controls. zafer

        You're right, but I have only one form, my form contains two Panels and each Panels contains some Controls. Your foreach statements give me my Panels only. Thanks

            Use two foreach statements. Like this: foreach (Control oCtrl in this.Controls){ // Do something foreach(Control oCtrl1 in oCtrl.Controls){ // Do something } }

                In that case you can use conditional recursion by checking if current control has child controls.

                    Each 'container' has it's own control collection so you have to loop each one of them. The most easiest way is to create a method for listing controls and call this method recursively passing the collection (for example List) as a parameter. Pseudo-code would be something like:

                    GetControls(List controlList, Control parent) {
                    foreach (Control ctrl in parent.Controls) {
                    controlList.Add(ctrl); //or whatever you want to do
                    GetControls(controlList, ctrl);
                    }
                    }

                    The need to optimize rises from a bad design

                      Well then, just find something else to do with your time. If it's not freakin' obvious what you have to do, and that "not wanting to" isn't a viable tack if you want to accomplish your goal, you shouldn't be a programmer. I bet you could find a job sweeping standing water off of sidewalks. Oh wait, that requires a little effort as well. Oh wait! Try just staring off into space. That should keep your feeble excuse for a brain busy.

                        You guys are wasting your time. He probably thinks "recursion" is having to visit the toilet more than once in a 60-second time frame.
