Hi,

I am getting the below error when I am trying the remove the tabitem from tabcontrol.

Cannot modify the logical children for this node at this time because a tree walk is in progress. Please find the below stack trace.

fishboneControl.Remove(PersonPage);

C#

public void Remove(FishbonePage page)
       {
           for (var i = 0; i < Items.Count; ++i)
           {
               var currentPage = GetFishbonePage(Items[i], i);
               if (currentPage == null || !ReferenceEquals(currentPage, page))
               {
                   continue;
               }

               Items.RemoveAt(i);
           }

           EnsureChildPages();
       }
