We had a requirement to add Copy/Paste icons the RadFileExplorer toolbar. That was the easy part. Getting them to call into the native Copy/Paste functions that are used by the Context Menus proved to be challenge.

Support provided me the solution below but it would have been nice to have OOB:

			function CopyFiles() {
				var fileExplorer = $find("<%=RadFileExplorer1.ClientID%>");
				fileExplorer.copyItems(fileExplorer.get_selectedItems());
			}
			function PasteFiles() {
				var fileExplorer = $find("<%=RadFileExplorer1.ClientID%>");
				fileExplorer.paste(fileExplorer._getCurrentFolderItem())
			}

This problem is reproducible with the FileExplorer control only when is set with a thumbnails view-mode. 

For large directories we would like to set the initial sort order to descending so we could see the newest files first.

Other times we would like to have the initial sort be by filename descending.

We want to set this declaratively on the control or in the .net code behind on initial page load.

Support custom upload dialog by overriding the built-in RadWindowManager within RadFileExplorer with a custom RadWindow upload dialog.

We need more than just adding meta data to uploaded files but must have complete control over this custom Radwindow upload dialog.

Thanks in advance,
