Maximum file size

Reply Quote

hi,

I Have a couple of questions about the maximum filesize of the ajax uploader.

Now I'm using

fileUploader.VALIDATEOPTION.MaxSizeKB = "10240"

for setting the maximum filesize, But actually I want a maximum size for all items together.

The seccond problem is, i get a popup whit the error.

I actually don't want a popup but a message on the site or something. And I want to change the text of the alert but I can't find how to do this.

Is it possible to change?

Hi pbwbart,

Please try the example below

<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void attachment1_AttachmentRemoveClicked(object sender, AttachmentItemEventArgs args)
{
hfTotalSize.Value=(int.Parse(hfTotalSize.Value)-args.Item.FileSize).ToString();
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<CuteWebUI:UploadAttachments ID="attachment1" runat="server" OnAttachmentRemoveClicked="attachment1_AttachmentRemoveClicked">
</CuteWebUI:UploadAttachments>
<asp:HiddenField ID="hfTotalSize" runat="server" Value="0" />
</form>
</body>
</html>
<script>
var totalSize = document.getElementById("<%=hfTotalSize.ClientID %>");;
//max size setting 1024000=1mb
var MaxSizeKB=1024000;
function CuteWebUI_AjaxUploader_OnSelect(files) {
for (var i = 0; i < files.length; i++) {
totalSize.value = parseInt(totalSize.value) + files[i].FileSize;
}
if (parseInt(totalSize.value) > MaxSizeKB) {
for (var j = 0; j < files.length; j++) {
totalSize.value = parseInt(totalSize.value) - files[j].FileSize;
}
//handle the error message here
alert("File size limit exceeded");
return false;
}
}
</script>

Regards,

Ken

Thanks,

For the most part this will work,

only

"AttachmentRemoveClicked"

Won't be triggert while removing a file from the list so the counting goes wrong if a user deletes a file from the list

Dear pbwbart,

"attachment1_AttachmentRemoveClicked" is fired when you remove file. I have tested it. Please set breakpoint within "attachment1_AttachmentRemoveClicked" and test it again.

Thank you for asking

I created a small test to check it out

Public Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim fileUploader As New CuteWebUI.UploadAttachments
fileUploader.ID = "fileUploader"
fileUploader.ManualStartUpload = "true"
AddHandler fileUploader.AttachmentRemoveClicked, AddressOf fileUploader_AttachmentRemoveClicked
Dim btnAddFiles As New Button
btnAddFiles.ID = " btnAddFiles"
btnAddFiles.CssClass = "Inputbutton"
btnAddFiles.Text = "Toevoegen"
btnAddFiles.Attributes.Add("OnClick", "document.getElementById('" & form1.ClientID & "_fileUploader').startupload();return false;")
Dim hfTotalSize As New HiddenField
hfTotalSize.ID = "hfTotalSize"
hfTotalSize.Value = "0"
form1.Controls.Add(fileUploader)
form1.Controls.Add(New LiteralControl("<br />"))
form1.Controls.Add(btnAddFiles)
form1.Controls.Add(hfTotalSize)
End Sub
Sub fileUploader_AttachmentRemoveClicked(ByVal sender As Object, ByVal args As CuteWebUI.AttachmentItemEventArgs)
Dim hoi As String = "hoi"
End Sub
End Class

but if I set a debugpoint at row26 nothing happens while clicking the red cross

So somewhere the AttachmentRevomodeClicked isn't triggert correctly,

Downloaded the new version of the uploadcontrol today.
