How do I access the FILES dialog box via customization project (or even in the UI itself)?

Hi @dgross54 

This dialog box is part of the main frame screen and is hidden for customizations. What do you want to customize in that dialog?

You could have access to the files of the appointment by doing:

Guid[] files = PXNoteAttribute.GetFileNotes(sender, row);
foreach (Guid fileID in files)
{
    // Your logic
}

Also you can customize the upload dialog box logic by creating by adding 

Do not forget to set the session key on the dialog:

Then in the code you can have a button with specific custom logic:

#region UploadButton
public PXAction<GCSetup> UploadButton;
[PXUIField(DisplayName = "YourButtonLabelHere", Enabled = false)]
[PXButton]
protected virtual IEnumerable uploadButton(PXAdapter adapter)
{
	if (AppointmentRecords.AskExt() == WebDialogResult.OK)
	{				
		const string psk = "YourSessionKeyHere";
		PX.SM.FileInfo info = PX.Common.PXContext.SessionTyped<PXSessionStatePXData>().FileInfo[psk] as PX.SM.FileInfo;
		if(info != null)
		{					
			FSAppointment config = AppointmentRecords.Current;

			// Your Logic Here

			PXNoteAttribute.AttachFile(AppointmentRecords.Cache, config, info);
			PXNoteAttribute.SetFileNotes(AppointmentRecords.Cache,config, info.UID.Value);
			Actions.PressSave();
		}
	}
	return adapter.Get();
}
#endregion

Hope this helps

Happy New Year!
