ASPxTreeList - How to get values of parent and child nodes

created 13 years ago

Hello:
I would like to get the parent and child values in ASPXTreeList and concatenate their values in order to get the URL of the form I want to access for example:
Users > Add New User
This one I could make it in the attached example, but in the case the node has children, I don ́t know how to get those values and concatenate them to form the complete URL like this:
Users > Assign > PC
                      > Notebook
                      > Mouse
I hope you can help me, Thanks

    Hello,
    I believe that you can use TreeListNodeIterator to iterate through child nodes and collect their values. Call the ASPxTreeList.CreateNodeIterator method to get the Iterator reference.

      I modified my example and now I get the values of Parent, Child and GrandSon,I do it by clicking on buttons but now I want to save the values in session variables every time I select a node, without using those buttons, How can I do this? I need you to modify my ATTACHED PROJECT because I already checked your examples and I couldn't find an example like this, thanks.

      Hello,
      Thank you for your update. I believe you can use the code from the E2157 - OBSOLETE: How to change the style of a parent node's selection checkbox if some of its child nodes are selected Code Central example to accomplish this task:
      - Set the ASPxTreeList.SettingsBehavior.ProcessSelectionChangedOnServer property to "True";
      - Handle the server-side ASPxTreeList.SelectionChanged;
      - Iterate through nodes' collection;
      - Save the required information in the Session state.
      Thanks,
      Mike
