Except the error in attribute name (data-action and data-ction), what wrong with your code?

I think there is a slight difference between ctr.Attributes("data-action") and ctr.Attributes("data-"a"ction") an "a" is missing

As System.Web.UI.AttributeCollection does not have a public definition for GetEnumerator so the only way that you have is just using Keys property of this class in order to get all attributes' keys

public void CheckControls(ControlCollection controls)
   {
       foreach (Control control in controls)
       {
           WebControl ctr = control as WebControl;
           if (ctr != null)
           {
               foreach (string key in ctr.Attributes.Keys)
               {
                   //Do whatever you want
                   if (key == "sth")
                   {
                       string dataAction = ctr.Attributes[key].Trim().ToLower();
                       control.Visible = false;
                   }
               }
               if (control.HasControls() == true)
                   CheckControls(control.Controls);
           }
       }
   }
