Question

I have 45 dropdown lists in my asp page. There are some methods that I can apply to all of these dropdowns. Is it possible to convert them into an array of dropdowns for ease of use?

Answer 1

I would use recursion to look for all dropdowns on your page. Based on this post it would be something like:

    public static List<T> FindControls<T>(System.Web.UI.ControlCollection Controls) where T : class
{
List<T> found = new List<T>();
FindControls<T>(Controls, found);
return found;
}
    private static void FindControls<T>(System.Web.UI.ControlCollection Controls, List<T> found) where T : class
    {
         if (Controls != null && Controls.Count > 0)
         {
              for (int i = 0; i < Controls.Count; i++)
              {
                   if (Controls[i] is T)
                   {
                        found.add(Controls[i] as T);
                   }
                   else
                        FindControl<T>(Controls[i].Controls, found);
              }
         }

       }

Once you have your list of dropdowns you can apply whatever methods you see fit.
