Hello:
I am using the slick mvc3 sample project as my base. I've added a custom filename generator and code to resize the image. I'd like to show the user a thumbnail of the image after the upload but can't find the filename that the custom filename generator used. Is it possible to get this information in the OnClientUploadFileEnded javascript function?
Thanks,
|

You can set data in the UploadStreamProvider via the file.Data dictionary, like this:
file.Data["thumbUrl"] = "somevalue";
Then, in the OnClientUploadFileEnded function, you can retrieve the value like this:
function onFileUploadEnded(file)
{
var status = file.get_Status();
if (status.errorType == "None")
{
var thumb = file.getElementById("thumb");
thumb.src = status.thumbUrl;
thumb.style.display = "block";
}
else
{
// TODO: probably an invalid image -- handle the error
alert("Invalid image!");
kw("<%=slickUpload.ClientID %>").remove_File(file);
}
}
