Help with downloading file

[Chris]

Hello, I am trying to download a file from SQL Server...here is the method I normally use.

Private Sub gvMain_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles gvMain.ItemCommand
      If e.CommandName = "DownLoad" Then

          sch = New clsReport
          Dim arr As ArrayList = sch.DownloadLetter(e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("ID"))

          Dim fil As Byte() = arr(0)
          Dim nam As String = arr(1)
          Dim ext As String = arr(2)

          If Not fil Is Nothing Then
              Response.Clear()
              Response.AddHeader("Content-Dispostiotion", nam & "." & ext)
              Response.AddHeader("Content-Length", fil.Length.ToString)
              Response.ContentType = "application/octet-stream"
              Response.BinaryWrite(fil)

          End If
      End If



  End Sub

Do I need to do something with the RadAjaxManager here...or the RadScriptManager? 
Thanks for any help.

Hi Chris,

Downloading a file during an AJAX postback is unsupported feature. Please see this help topic describing how you can stop AJAX when only you request the file download.

All the best,
Simon

Do this by opening a radWindow, that loads another aspx page and executes the download. I have been trying this...but I am having issues specifying the path to the page using radOpen()

Probably this demo will help you define and pass the url to the page to the radopen method. Browse the online documentation of RadWindow if more details are needed.
