Server Folder/File Structure in Treeview

[Kurosh]

I've just started evaluating the telerik radcontrols for silverlight and so far I am very impressed. I have run into an issue and I was hoping that someone could help me resolve this.

Problem: I need to traverse through folders and files located in a folder under the root of a web application and populate the radtreeview based on folder/file names. Populating the treeview is not an issue as I will be doing that in the code behind. However I am not sure about accessing the server folder/file structure and getting the paths and folder/file names.

Any help would be greatly appreciated and thanks in advance.

Hello Kurosh,


I prepared a sample for which uses WCF RIA Services. I created a service method that iterates over a Folder in the WebSolution and returns a HIerarchy of Objects ( ObservableCollection<DataItems>) that is used in the client to show a hierarchical data in the RadTreeView. Please examine the solution and let us know if it helped you.

Hello Chandu,

 The following recursive code should do the work, no changes in XAML (SL project):

private DirectoryInfo startDirectory = new DirectoryInfo(@"C:\Users\pmladenov\Desktop\279102_TreeViewFoldersInWebPart\TreeViewFolders.Web\FolderA");
        private string startDirectoryString = "FolderA";
        public void DoWork()
        {
        }

        public ObservableCollection<DataItem> GetSomeData()
        {
            if (startDirectory != null)
            {
                ObservableCollection<DataItem> collection = new ObservableCollection<DataItem>();
                DataItem dataItem = new DataItem() { Name = startDirectoryString };
                this.AddChildCollection(dataItem, startDirectory);
                collection.Add(dataItem);
                return collection;
            }
            return null;
        }

        private void AddChildCollection(DataItem dataItem, DirectoryInfo currDirectory)
        {
            foreach (DirectoryInfo item in currDirectory.GetDirectories())
            {
                DataItem child = new DataItem()
                {
                    Name = item.Name.ToString()
                };
                this.AddChildCollection(child, new DirectoryInfo(item.FullName));
                dataItem.Children.Add(child);
            }
        }

I have a question
to view files in the trewview

Carpeta_SubCarpeta_SubSubCarpeta_NombreArchivo  how I can do

[Petar Mladenov]

Hi Pablo,

I am not sure I completely understand this scenario. The RadTreeView provides ItemTemplateSelector ItemContainerStyleSelector which allows you to set different templates / styles on the different levels.
If this does not answer your question, is it possible for you to open a new support thread with more details about your specific scenario. Thank you in advance.

Hi Pablo,

In your picture I can see a File / Folder tree structure and that is why I have attached a sample project implementing such structure with RadTreeView. Let us know if this is your requirement.
