Hi,
Is it possible to set a panel visible when at least one file is uploaded and sets it to false when there's no file uploaded (or the uploaded files are deleted/removed) ?

Hi Stan, That can be done but requires some JavaScript programming. You would start a timer and keep checking how many files the uploader has with this function: http://www.essentialobjects.com/ViewDoc.aspx?t=JSDoc.Public.AJAXUploader.getPostedFiles.htmlIt returns an array and when you see the length of the array is zero, you would hide your panel. Thanks

Sorry for my ignorance,
But in fact I don't know how to check the length of the array.
I suppose I have to set an handle to an event (to the AjaxUploader control).
And in the same time, I need to disable the "final" submit button (this one that validates the whole process) when there's no uploaded files and set it to enable where there's at least one uploaded file.
If someone could help me.. :)

Hi Stan, You would want to go over some basic JavaScript stuff. You can probably start from here: http://www.w3schools.com/js/default.aspThose are quite easy with JavaScript but obviously JavaScript is a client side language, so it's vastly different thant server side language you've been using such as C# and VB.NET. Once you know how JavaScript works, you can use the length property of the array to get the length of the array and the disabled property of the button to disable the button. Thanks

Hi,
In fact my problem is that I can't access the getFilesPosted() function.
When I invoke this function I get a message saying this object doesn't support this method or property (french translation).
Here's my code :
javascript part :
var isInterval=false;
var uploadObj;
function ProgressHandler(uploader, total, received)
{
if (!isInterval)
{
isInterval=true;
uploadObj=uploader;
timer=setInterval("checkFile()",1000);
}
}
function checkFile()
{
var postedFiles=uploadObj.getPostedfiles();
if (postedFiles.length>0)
{
bla bla
}
}
From the EO
<eo:AJAXUploader id="AJX1" ClientSideOnProgress="ProgressHandler" ...... </eo>
I know how to change the disabled property from a button.
My problem is just to know why I can't invoke the getPostedFiles method.
If you could help...
Stan

It should be "getPostedFiles", you have "getPostedfiles" in your code. It's case sensitive.

I am not sure how you get the list. But getPostedFiles is definitely there. It didn't exist in early versions though, so you might want to upgrade to the latest version.
