Implimentation download custom button functionality in RAD File explorer

[sandhya]

Hi Telerik,

In RAD File explorer grid context menu if i click on download it should download the file.How can we achieve this task.
Is there any demo example with code .please can you share it me..

How to get the physical path from server side.?
I added custom download file button in grid context menu.
This is my code:
Client side:
--------------

 

 

function DownloadFileWindow(oGridMenu, args) {

 

 

 

 

var domElem = args.get_targetElement();

 

 

 

 

var text = $telerik.$(domElem).text();

 

 

 

 

//var isFolder = text.indexOf(".") == -1;

 

 

 

var gridContextMenuItems = oGridMenu.get_allItems();

 

 

 

 

for (var i = 0; i < gridContextMenuItems.length; i++) {

 

 

 

 

var menuItem = gridContextMenuItems[i];

 

 

 

 

if (menuItem.get_value() == "Download_File") {

 

 

OnClientFileOpen(sender, args)

 

__doPostBack(

 

"download");

 

 

}

 

}

 

}

Server side:

radFileExplorer.GridContextMenu.OnClientItemClicked = "DownloadFileWindow";

I am calling my function like this

 

 

string userSelection = Request.Params.Get("__EVENTTARGET");

 

 

 

 

if (userSelection == "download")

 

 

{

 

DownLoadFile();

 

}

private

 

 

void DownLoadFile()

 

 

{

 

 

 

string TargetFile = here i need physical path of the file
//radFileExplorer.TreeView.SelectedNode.GetFullPath("/");//radFileExplorer.Configuration.ViewPaths;

 

System.IO.

 

FileInfo file = new System.IO.FileInfo(TargetFile);

 

 

 

 

//-- if the file exists on the server

 

 

 

//set appropriate headers

 

 

 

if (file.Exists)

 

 

{

 

 

 

FileStream liveStream = new FileStream(TargetFile, FileMode.Open, FileAccess.Read);

 

 

 

 

byte[] buffer = new byte[Convert.ToInt32(liveStream.Length) + 1];

 

 

liveStream.Read(buffer, 0,

 

Convert.ToInt32(liveStream.Length));

 

 

liveStream.Close();

 

Response.ClearHeaders();

 

Response.ClearContent();

 

Response.Clear();

 

Response.ContentType =

 

"application/octet-stream";

 

 

Response.AddHeader(

 

"Content-Length", buffer.Length.ToString());

 

 

Response.AddHeader(

 

"Content-Disposition", "attachment; filename=" + file.Name);

 

 

Response.BinaryWrite(buffer);

 

}

 

}

Hi Sandhya,

I believe the following Live Demo and help article will help you solve this case:
FileExplorer / Filter files and download
Adding a custom button to the toolbar and an item to the tree context menu
