Hi,

I was building an UltraWinTree and bind it to objects.

My original dataset in database for Test1 has 3 levels, after I insert a new record of Test1 on any of the existing level, it’s shown correctly, but if I insert a new record of Test1 into the database on a new level, i.e. adding a child to a level3 Test1 node, when I rebuild the tree, it doesn’t show this new node on the new level (level4).

My original Test2 dataset in database has 4 levels. The tree does show all nodes on all the levels properly. Again, when I tried to insert a record of Test2 into the database on level5, it’s not shown either.

It looks like the tree is not shown correctly when I want to add a node on a new level. I attached some code that I used to build the tree. Hope it will help explain my issue.

Thanks. 

       public void BuildTree(string root, UltraTree treeView)

         {

             if (root == "TestRoot1")

             {

                 List<Test1> rootList = new List<Test1>();

                 foreach (Test1 r in LoadData_Test1())

                 {

                     if (r.Name == root)

                     {

                         rootList.Add(r);

                     }

                 }

                 treeView.SetDataBinding(rootList, null);

             }

             else if (root == "TestRoot2")

             {

                 List<Test2> rootList = new List<Test2>();

                 foreach (Test2 r in LoadData_Test2())

                 {

                     if (r.Name == root)

                     {

                         rootList.Add(r);

                     }

                 }

                 treeView.SetDataBinding(rootList, null);

             }

         }
