It is very frustrating that it is not possible to upload multiple files. The solution suggested at the link posted in this
thread is really not as powerfull as I had hoped for.
The problem is that every time the add button is clicked in order to move the selected file to the selected list, it will actually upload the file; i.e. the file is
not uploaded when the
upload button is clicked. When the upload button is clicked they are just saved to the server from memory. The solution will therefore also have all pictures in memory before clicking the upload button.
Well, my first though (probably not well though-through) was to add the files selected to the list dynamically (client-side) using java script and then upload them using server-side as in the example. The thing I missed was the fact that I cannot post items added through java script, or
am I wrong on this?
Code:
<html>
<head>
<script language="javascript">
function addFile()
{
var option = document.createElement("option");
option.text = document.upload.file.value;
document.upload.files.options.add(option);
}
</script>
</head>
<body>
<form name="upload">
<input id="file" type="file" onchange="addFile();" style="width:400px;" /><br/>
<select id="files" multiple="true" style="width:400px;" size="10" />
</form>
</body>
</html>
I found a similar version
here.
Since the page is not reloaded, the items are not really added to the page why the ASP.NET server-side code cannot see the items added. Moreover, the above script only add the text and not the input object (this could be fixed).
Then I have searched for another solution on the web, however, no solutions that would do the trick have come up.
How can I make an good upload solution? This problem must have been solved before
I found several solutions where java script was used to generate an MSXML object and the post the document to the web server, where an ASP document picked up the request, but I can't make it work. See e.g.
here...
Any comments on this solution? And is it possible to have ASP.NET pick up the request? Experiences?
I am dying for a solution. This problem is super annoying.
Thanks, Jacob.
