Multiple RadTreeNode node

[Steven]

i am current able to get all users for the first node (teamLeaderNode), but on the second node (projectGroupNode) it only add one node, even there are more record for projectgroupnode. projectSubGroupNode is only 1 record display even more record on the database. WOuld you be able advise, thank you



 private void BuildProjectTree()
        {
    
            EntityCollection<VwProjectCollectionEntity> collection = GetProjectData();
    
            treProjects.Nodes.Clear();

            RadTreeNode teamLeaderNode = null;
            RadTreeNode projectGroupNode = null;

            RadTreeNode projectUserResponsibleNode = null;
            RadTreeNode projectWorkplaneNodeNode = null;
            RadTreeNode projectNode = null;
    
            foreach (VwProjectCollectionEntity p in collection)
            {

Is there any methods to remove duplicate nodes. Please advise. thx

Hi,

Since you are creating the TreeView programmatically the issue is most probably related to the data you are binding it to. Unfortunately I don't have the data you are using, so it's impossible for me to reproduce the issue on my end.

What I would suggest is to check whether the GetProjectData method returns all the nodes you are expecting. Also, you can try substituting RadTreeView for the ASP.NET TreeView and see whether it binds correctly. If it does, then the issue is caused by RadTreeView itself and we will do our best to resolve the issue.
