'Declaration Public Property UploadedFilesDirectory As String
public string UploadedFilesDirectory {get; set;}
This property impacts all ToolbarUploadButton controls on the toolbar. Each ToolbarUploadButton has a ToolbarUploadButton.Upload property representing the upload dialog that will be displayed to the user when the button is clicked. The user can use this dialog to upload files. This upload dialog, by default, will upload files to the directory specified by this property. If you have multiple ToolbarUploadButton controls on the toolbar, they will all upload to this directory by default. If you want to change this so multiple ToolbarUploadButton controls upload to different directories, you must do this on the ToolbarUploadButton level instead of setting this property, which acts globally.
