Hi, I've got some questions concerning getting the save dialogue to
popup when a link is clicked on. The particular issue I'm having is
that the file is returned dynamically (via a search) and I need to get
the file name for the save dialogue. I've heard that using ADO streams
keeps it from opening in the browser, and forces the popup for
"Save/Open" - does this work?
The ADO stream that I would like to use in the codebehind is SIMILAR to
this:
Dim FileName
Dim FullFileName
FileName = 'assigned elsewhere from SQL Query datatable
FullFileName = " 'assigned elsewhere from SQL Query datatable
Response.ContentType = "application/x-unknown"
Response.Addheader "Content-Disposition", "attachment;
filename=" &
chr(34) & FileName & chr(34)
Response.Binarywrite GetBinaryFile(FullFileName)
Function GetBinaryFile(ByVal FileSpec)
Const adTypeBinary = 1
Dim objStream
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Open()
objStream.Type = adTypeBinary
objStream.LoadFromFile (FileSpec)
GetBinaryFile = objStream.Read()
Set objStream = Nothing
End Function
Now how do I make the TemplateColumn in the ASP.Net portion linked, or
run this particular code? or is there a better way?
My column:
<asp:TemplateColumn
ItemStyle-HorizontalAlign="Center"><ItemTemplate><asp:Image ID="thumb"
runat="server" /></ItemTemplate></asp:TemplateColumn>
Do I use an anchor element? Some DataItem element? I need to get the
filename via the codebehind, so it needs to happen there. The filename,
thumbnails, etc are all grabbed in the DataGrids ItemDataBound
function.
Thanks!
James
