Dear SergeyC,
Client validation:
<script type="text/javascript">
function CuteWebUI_AjaxUploader_OnSelect(files) {
var selectedSize = 0;
for (var i = 0; i < files.length; i++) {
selectedSize += files[i].FileSize;
}
//if selected files size is greater than this value, will stop the upload
if (selectedSize > 1024 * 1024 * 1024) {
alert("the selected file size is "+ FormatSize(selectedSize)+",you only can upload 1G files");
return false;
}
}
</script>
Server side validation:
void Uploader_FileUploaded(object sender, UploaderEventArgs args)
{
//validate the total size of uploaded files or validate the used space of destination folder
}
Thank you for asking
