Hello,
The UploadComplete() function seems to be getting called twice and thus is adding records to SQL twice.
protected void SlickUpload1_UploadComplete(object sender, Krystalware.SlickUpload.Controls.UploadStatusEventArgs e)
{
uploadPanel.Visible = false;
resultPanel.Visible = true;
if (e.UploadedFiles != null && e.UploadedFiles.Count > 0)
{
resultsRepeater.DataSource = e.UploadedFiles;
resultsRepeater.DataBind();
resultsRepeater.Visible = true;
//Response.Write(e.UploadedFiles.Count().ToString());
foreach (UploadedFile file in e.UploadedFiles)
{
....
}
}
else
{
resultsRepeater.Visible = false;
}
TabInit("uploadphotos");
}
<script type="text/javascript">
function cancelUpload() {
kw.get("<%=SlickUpload1.ClientID %>").cancel();
}
function startUpload() {
kw.get('<%=SlickUpload1.ClientID %>').submit();
}
function fileAdded(file) {
document.getElementById('<%=btnUpload.ClientID %>').style.display = 'block';
var extImage = file.getElementById("extImage");
extImage.src = "FileIcon.ashx?ext=" + file.extension;
}
function fileRemoved(file) {
var SlickUpload1 = kw.get('<%=SlickUpload1.ClientID%>');
var files = SlickUpload1.get_Files();
if (files.length == 0) {
document.getElementById('<%=btnUpload.ClientID %>').style.display = 'none';
}
}

Duplicate event firing usually happens because the events are wired up twice. I see the event wired up in the markup (OnUploadComplete="SlickUpload1_UploadComplete"). Do you have AutoEventWireup=true set in the page declaration or web.config? Or are you wiring up the event in the codebehind?
If not, send the .aspx, codebehind, and web.config to chrish at krystalware dot com and I'll have a look.

Thanks Chris for your reply!
Although I did have AutoEventWireup=true set in the page declaration, after removing it, I'm still let with the same issue. I could find the event wired anywhere else, so I've sent you the aspx, codebehind and web.config file via email.
Thanks again for your help!

Hello
I am having the same issue. Has anyone found a fix for this? I have the event wired up only in the mark up and page's AutoEventWireup is set to true.

If you have AutoEventWireup="true", try removing the manual wireup in the page markup. If that doesn't work, send your .aspx, codebehind, and web.config to chrish at krystalware dot com and I'll take a look.

I'm seeing this too, and I am also using a case where I set AutoUploadOnPostBack="false" , and then manually call .submit() on the SlickUpload control to being the upload. Chris, have you managed to duplicate this, and/or have a fix?
One other note, I've tried removing the wireup in the page markup, in which case I lose the event altogether, and (separately) I've tried performing the wireup in the codebehind by adding an event handler in page_load, which gets me back to seeing the event firing twice.
So, two observations in total:
1) Is there any possibility that AutoUploadOnPostBack being false is causing the auto event wireup to not work?
2) Does calling .submit() manually from the page seem to be related to the event firing twice?

Shoot me your .aspx, codebehind, and web.config via email (chrish at krystalware dot com) and I'll take a look.
