I want to generate a tree view using asp in which when I click the file (not the folder) the file should be deleted
I found this on net but how can I modify to delete a file when clicked on it.

Here is a link for a very simple tree view: http://www.htmlforums.com/html-xhtml/t-how-do-i-make-an-expandable-list-43732.html
It can be modified to allow for multiple tree views as shown in this example.
<script type="text/javascript">
function toggleBox(id){
if (document.getElementById(id).style.display = = "") {
show = "none";
} else {
show = "";
}
document.getElementById(id).style.display = show;
}
</script>
</head>
<body>
<table width="100%" align="center">
<tr>
<td><a href="javascript:toggleBox(1)">+</a> <a href="" >Drive Letter</a></td>
</tr>
</table>
<table width="100%" border="0" align="center" id="1" style="display: none;">
<tr>
<td bgcolor="#FFFFFF" width="30"> </td>
<td bgcolor="#FFFFFF" width="*">
<a href="javascript:toggleBox(2)">+</a> <a href="" >Folder</a></td>
</tr>
</table>
<table width="100%" border="0" align="center" id="2" style="display: none;">
<tr>
<td bgcolor="#FFFFFF" width="70"> </td>
<td bgcolor="#FFFFFF" width="*">
<a href="../drive.asp?operator=Delete&file=C:\folder\filename.txt">File</a></td>
</tr>
</table>
</body>
</html>So now with an easy to use tree the next thing you might want to do is use images instead or with the names in the tree as follows:
%><td width="10"><a href="javascript:toggleBox(<%= intCount1 %>)">
<img border="0" src="../Graphics/Folder.gif"></a><a href="" ></a></td><%Also note that a variable “intCount1” is used instead of hard coding the javascript:toggleBox value, a variable can also be used with the ID to make this code very dynamic with some loops.
Now for the deleting file: A static tree makes no sense as you will need to change the code each time a file is deleted. For a dynamic list you will need to search the drive and write the file names into variables in the anchors. Start your tree with the root C:\ (or whatever your root/folder that you want to start is) Then search for folder names and files inside the folders as you loop through this write the values into the anchors. Example:
<a href="../drive.asp?operator=Delete&file=<%= Path1 %>Path1 will be the path to the file example: (C:\folder\filename.txt).
So now that the tree is created when you click on the text or graphic corresponding to the path you will be directed to the html link with a querystring containing two values. The first value (in this case operator) will give a conditional statement, the second (File) will point to the path of the file you wish to delete.
If operator = Delete Then
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
objFSO.DeleteFile("C:\folder\filename.txt")
End ifWith C:\folder\filename.txt being the value contained in Path1
My assumption being that you are asking about asp pages is that you will be using vbscript and are on a windows server.
