asp.net中使用TreeView顯示文件

在ASP.NET中,TreeView的使用很普遍,把它利用上來

首先加入TreeView控件

1. <asp:TreeViewID="driverInfoView"runat="server"ImageSet="XPFileExplorer"OnTreeNodePopulate="driverInfoView_TreeNodePopulate">
3. </asp:TreeView>

當頁面加載的時候,寫下以下代碼

2. }
3. this.driverInfoView.Nodes.Add(newNode);
4. }
5. }

設置TreeView節點的事件

C#代碼

1. protectedvoiddriverInfoView_TreeNodePopulate(objectsender,TreeNodeEventArgse)
2. {
3. DirectoryInfodictInfo=newDirectoryInfo(e.Node.Value);
5. foreach(DirectoryInfodirectoryindictInfo.GetDirectories())
6. {
7. TreeNodenewNode=newTreeNode();
8. newNode.Expanded=false;
9. newNode.PopulateOnDemand=true;
10. newNode.Text=directory.Name;
11. newNode.Value=directory.FullName;
12. e.Node.ChildNodes.Add(newNode);
13. }
15. foreach(FileInfofileInfoindictInfo.GetFiles())
16. {
17. TreeNodenewNode=newTreeNode();
18. newNode.Text=fileInfo.Name;
19. newNode.Value=fileInfo.FullName;
20. e.Node.ChildNodes.Add(newNode);
21. }
22. }
