Using the TreeView to display XML in WPF

Background:

Wrote a CS tool, want to open a folder in the client browser window to display the server-side folder.

Problem:

To the ready-made folderbrowserdialog somehow applied to this scene, had to write a simple window. Server-side WCF, which wants to send XML to the client from the server side, is displayed in the client with the TreeView.

Code:

Xaml:

<Windowx:class= "Wpfapplication1.myfolderbrowserwindow"xmlns= "Http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x= "Http://schemas.microsoft.com/winfx/2006/xaml"Title= "Browse Server folder"Height= "+"Width= "+"ResizeMode= "Noresize"windowstartuplocation= "Centerowner">    <window.resources>               <hierarchicaldatatemplatex:key= "ItemTemplate"ItemsSource="{Binding Xpath=folder}">            <TextBlockText="{Binding [email protected]}"/>        </hierarchicaldatatemplate>    </window.resources>    <Grid>                <TreeViewName= "TreeView"ItemsSource="{Binding}"treeviewitem.expanded= "treeview_expanded">            <treeview.itemtemplate>                <hierarchicaldatatemplateItemsSource="{Binding Xpath=folder}">                    <StackPanelOrientation= "Horizontal"Margin= "2">                        <ImageSource= "Folder2.png"Width= "+"Height= "+"Snapstodevicepixels= "True"/>                        <TextBlockText="{Binding [email protected]}"Margin= "5,0"/>                    </StackPanel>                </hierarchicaldatatemplate>            </treeview.itemtemplate>        </TreeView>    </Grid></Window>

C#:

Before the window is opened, the server side first begins with a string, including the server name and XML that consists of the System.IO.DriveInfo.GetDrives (). Then each time a level is expanded, the triggering event gets a list of subfolders at the next level. (in order to have that triangle ...) ）

 Public Partial classMyfolderbrowserwindow:window {//string format: <folder name=\ "servername\" ><folder name=\ "\ C" Fullpath=\ "c:\\\" ></Folder></Folder>         Public stringrootfolders {Get;Set; }  PublicMyfolderbrowserwindow () {InitializeComponent ();  This. Loaded + =window2_loaded; }        voidWindow2_loaded (Objectsender, RoutedEventArgs e) {XmlDataProvider XDP=NewXmlDataProvider (); Xdp. XPath="Folder"; XmlDocument xd=NewXmlDocument (); Xd.            LOADXML (rootfolders); Xdp. Document=xd;  This. TreeView.Items.Clear ();//items and Itemsource can only have one effect, want to use one, the other must be empty, but why items are not empty?             This. Treeview.datacontext =XDP; }        Private voidTreeview_expanded (Objectsender, RoutedEventArgs e) {TreeViewItem Item= E.originalsource asTreeViewItem; if(Item! =NULL)            {                if(item. Hasitems) {foreach(varChildIteminchitem. Items) {XmlElement element= ChildItem asXmlElement; if(!element. HasChildNodes) {stringFullPath = element. GetAttribute ("FullPath"); Element. INNERXML= Getchildfolders (FullPath);//"<folder name=\" wpf\ "/><folder name=\" mfc\ "/><folder name=\" delphi\ "/>";                        }                                            }                }                          } }         Public Eventfunc<string,string>getchildfoldersevent;  Public Delegate stringGetchildfolderseventhandler (Objectsender, Foldereventargs args);  Public EventGetchildfolderseventhandler GetChildFoldersEvent2; Private stringGetchildfolders (stringFullPath) {Foldereventargs args=NewFoldereventargs (); Args. FullPath=FullPath; returnGetChildFoldersEvent2 ( This, args); //return getchildfoldersevent (FullPath);        }    }     Public classFoldereventargs:eventargs { Public stringFullPath {Get;Set; } }
