Question

How do you get a specific nested control of dynamically created controls (i.e. the child of a dynamic control)? The FindControl() method does not work because it only deals with TopLevel dynamic controls I believe.

Answer 1

You need to recurse through your controls: (C# code)

   public static Control FindControl(Control parentControl, string fieldName)
    {
        if (parentControl != null && parentControl.HasControls())
        {
            Control c = parentControl.FindControl(fieldName);
            if (c != null)
            {
                return c;
            }

            // if arrived here, then not found on this level, so search deeper

            // loop through collection
            foreach (Control ctrl in parentControl.Controls)
            {
                // any child controls?
                if (ctrl.HasControls())
                {
                    // try and find there
                    Control c2 = FindControl(ctrl, fieldName);
                    if (c2 != null)
                    {
                        return c2; // found it!
                    }
                }
            }
        }

        return null; // found nothing (in this branch)
    }
