OnClientFileUploadRemoving

The OnClientFileUploadRemoving occurs before the file is about to be removed from the FileListPanel. The 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:

• set_cancel lets you prevent the row from being deleted.

• get_fileName the name of the file that is about to be removed from the uploaded files collection.

• get_row returns the row containing the file input field for the file that is just about to be removed (<LI> element)

• get_isFailed returns a boolean value, specifying if the file, which is about to be removed had passed the validation.

ASP.NET

<telerik:RadCloudUpload runat="server" ID="RadCloudUpload1" OnClientFileUploadRemoving="onClientFileUploadRemoving" ...>
</telerik:RadCloudUpload>

JavaScript

function onClientFileUploadRemoving(sender, eventArgs) {
	if (eventArgs.get_fileName().length > "10") {
		alert("Cannot delete files, which name's length is larger then 10 symbols");
		eventArgs.set_cancel(true);
	}

}
