OnClientFileUploading

The OnClientFileUploading occurs before the RadCloudUpload starts to upload the specified file to the Cloud Storage Provider. This event can be cancelled.

The event handler receives two parameters:

  1. The instance of the RadCloudUpload control firing the event.

  2. An eventArgs parameter containing the following methods:

  • get_row returns the created row from the FileListPanel section (<LI> element)

  • get_fileName returns the name of the file selected

  • set_cancel cancel the upload process

ASP.NET
<telerik:RadCloudUpload runat="server" ID="RadCloudUpload1" OnClientFileUploading="onClientFileUploading" ...>
</telerik:RadCloudUpload>
JavaScript
function onClientFileUploading(sender, eventArgs) {
	alert(eventArgs.get_fileName().length);
	if (eventArgs.get_fileName().length > 20) {
		eventArgs.set_cancel(true);
	}
	else {
		eventArgs.set_cancel(false);
	}
}
