    Hi ALL,

            I have one treeview on left panel which will bind from database, treeview have N no. of parents and each parent have N no. of childs and each child have N number sub child.

    On right side i have one textbox, when user enter some value and if it is one of treenode (Parent/Child/SubChild) then it should be selected..and on that particular selected node i need to fire treeview_nodechange event to bind right side grid.When user try to search text from textbox than treeview may be collapse or expanded, but once page load tree always be collapse.


               Sub Child21

               Sub Child22
               Sub Child23



               Sub Child21

               Sub Child22


    Here on page load grid will be collapsed, when user try to search text like "Child11" then Parent1 should be expand and Child11 should be selected.

    Same suppose user try to search "Sub Child22" than Parent2 and Child21 should be expand and "Sub Child21" should be selected

    And in both case treeview_nodechange event should be fire.

    I try this using

                       RadTreeView1.FindNodeByText(SearchText).Selected := true;

    Its running properly for parent node only, while i am trying with any child or sub child node it will give me error and got the node as null.

    Please help me on same.
