Removes all items from the upload list.
getImageUploader("ImageUploaderID").RemoveAllFromUploadList();
This method works in the same way as if the Remove All button is clicked. It works in all layouts
The contrary method AddAllToUploadList
which would correspond to the Add All button is not available due the security reasons.
If this method is required, you should create support case and order the private-label
version. In this case it is possible to discuss the including of this feature.
