  Hi there,
  
  i have a MDI-Application with one window which contains a TreeView.
  When loading the Window, I do the function FillUserList() and it works fine.
  But if I try to update th elist after that, it failed.
  This is my code for loading the data:
  
  

  rtvUserList.DataSource = null;

                

  lsmu = RfcCalls.GetListOfMainUsers();

                

  rtvUserList.DataSource = lsmu;

  rtvUserList.DisplayMember = "DisplayValue\\DisplayValue";

  rtvUserList.ValueMember = "Uname";

  rtvUserList.Name = "DisplayValue";

  rtvUserList.ChildMember = "SIPMainUser\\Subuser";

  rtvUserList.ClearSelection();

  I debugged it and my data is like it has to be.
  I tried a Refresh() but that also doesn't work.
  
  Any hint.
  
  Best Regards
  Manfred

  Hi Manfred,
  
  I'm having a similar issue since converting my code to Q3-2011, the treeview control does not display ist content
  
  

  switch (_InfoList[0].InfoType)

  {

      case InfoType.ItemInfo:

          break;

      case InfoType.JobInfo:

          this.radTreeViewSelection.ValueMember = "JobNo";

          this.radTreeViewSelection.DisplayMember = "Displayname";

          this.radTreeViewSelection.DataSource = _InfoList.Cast<JobInfo>();

          break;

      case InfoType.TaskInfo:

          this.radTreeViewSelection.ValueMember = "TaskNo";

          this.radTreeViewSelection.DisplayMember = "Displayname";

          this.radTreeViewSelection.DataSource = _InfoList.Cast<TaskInfo>();

          break;

      case InfoType.ResourceInfo:

          this.radTreeViewSelection.ValueMember = "ResourceNo";

          this.radTreeViewSelection.DisplayMember = "Displayname";  //"ResourceName"

          this.radTreeViewSelection.DataSource = _InfoList.Cast<ResourceInfo>();

          break;

      case InfoType.Statusinfo:

          this.radTreeViewSelection.ValueMember = "ProgresStatus";

          this.radTreeViewSelection.DisplayMember = "Statusname";

          this.radTreeViewSelection.DataSource = _InfoList.Cast<StatusInfo>();

          break;

      case InfoType.WorkplaceInfo:

          this.radTreeViewSelection.ValueMember = "WorkplaceNo";

          this.radTreeViewSelection.DisplayMember = "Displayname"; //"WorkplaceName";

          this.radTreeViewSelection.DataSource = _InfoList.Cast<WorkplaceInfo>();

          break;

   

      case InfoType.Worktypeinfo:

          this.radTreeViewSelection.ValueMember = "WorktypeNo";

          this.radTreeViewSelection.DisplayMember = "Displayname"; //"WorktypeName";

          this.radTreeViewSelection.DataSource = _InfoList.Cast<WorktypeInfo>();

          break;

  }

  
  Is that issue the same as  in  v2011.3.11.1124.
  
  Thanks for Feedback
  Daniel

  Hi Daniel,
  
  not really, for me it was a bug in the TreeView, they fixed it with  v2011.3.11.1124.
  
  For me to understand what you are doing, I think I need to know what you are doing in the Cast-Method.
  I think, there you should search for the root of your problem.
  
  Best Regards
  Manfred

  Hi Manfred and Daniel,

  Daniel, as Manfred said the issue is addressed in 2011.3.11.1124 version. You can download and try the internal build version (2011.3.11.1124) or you can wait for the Service Pack release scheduled for the end of this week. This Service Pack will contain additional fixes and improvements for RadTreeView control.
  
  If you continue to experience the issues, please open a support ticket and send as a sample project to investigate the issue locally. Thank you for your cooperation.
