ERP 9 New Record event

I searched here to no avail. I want to run some code when a New PO record is created. What event do I need to capture a New PO record?

For others, I just did this with the AfterToolClick method.

My code:

	//After making a new PO, select the supplier field instead of the PO date field.
	private void POEntryForm_AfterToolClick(object sender, Ice.Lib.Framework.AfterToolClickEventArgs args)
	{
		EpiTextBox txtVendorID;

		//MessageBox.Show(args.Tool.Key);
		if (args.Tool.Key != null )
		{
			if (args.Tool.Key.Equals("EpiAddNewnewPO"))
			{
				txtVendorID = (EpiTextBox)csm.GetNativeControlReference("00844fe6-60e6-4d26-bb91-0529be22e671");
				txtVendorID.Focus();
			}
		}
	}

Nice lead here:

Could also do it with EpiNotify, some help here:
