Question

I want to ask if I can loop in my controls, like textbox, dropdown list or etc, in which they are in a page’s user control. The scenario is that, assume I have a page called ‘Page.aspx’ and I have 3 user controls in that page(uc1, uc2 and uc3) and an asp panel (named PnlTab1) to contain all these controls in each user control.
I am using that code to reach my controls:

---

            UserControl uc1, uc2, uc3;
            uc1 = usercontrol1;
            uc2 = usercontrol2;
            uc3 = usercontrol3;

            foreach (Control c in uc1.FindControl("PnlTab1").Controls)
            {
                if (c is TextBox)
                    ((TextBox)c).Enabled = true;
            }

            foreach (Control c in uc2.FindControl("PnlTab1").Controls)
            {
                if (c is TextBox)
                    ((TextBox)c).Enabled = true;
            }
            foreach (Control c in uc3.FindControl("PnlTab1").Controls)
            {
                if (c is TextBox)
                    ((TextBox)c).Enabled = true;
            }

---

Now, I do not want to write each time ‘foreach (Control c in uc3.FindControl("PnlTab1").Controls‘ . Can I recursively do that?

Thank you all a lot!

no need for recursion, just another loop:

   UserControl[] ucs = new UserControl[3]{
         usercontrol1,
         usercontrol2,
         usercontrol3
   };
   foreach (UserControl uc in ucs){
        foreach (Control c in uc.FindControl("PnlTab1").Controls)
        {
            if (c is TextBox)
                ((TextBox)c).Enabled = true;
        }
   }
