please help me find a solution

I am about to develop a web application, basically it will be a treeview interface in the left frame ,which displays my folder/file structures on hard drive. when user click a node, the image files displays on the right frame ---Should I use ASP.NET ? IF SO, I couldn't find a treeview control in the tool box.

If i should download a control some where else, where is it and just want to make sure I don't want to use database or xml file to display the treeview, I hope to be looping through the file structure under my say,c:\sampleimages\image_1974\

thanksYou should use ASP.NET if your web server is IIS and you are willing to learn the technology that is central to Microsoft's development plans since 2002.

ASP.NET has been extended by numerous third parties for almost anything you can think of in the user interface. There are a number of perfected treeview webcontrols along with so many more items that are either new to you or much better than the controls built into ASP.NET. Microsoft's controls are there to get you started. They have built ASP.NET to be highly extendable and for it to be very easy to integrate a third party control or code.
You can find the third party products on this site's Control Gallery, www.123asp.com, and www.411asp.net.
