OnClientFileUploadRemoving

Updated on Aug 24, 2026

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);
	}

}
