Get Active Ledger from WindowManager

[kwesterlage]

How to we get to the underlying ledger in a ProTrust active document?

We are using the following code to access the underlying order in a ProForm active document:

Code: Select all

var windowManager = _sp.GetService<IWindowManager>();
var order = windowManager.ActiveDocument?.GetProperty("Order") as IOrder;

Using the IOrder to get the ledger where ss is the SelectServer object.

Code: Select all

// Get order guid.
Guid orderGuid = order.Identifier.Guid;

// Get light-weight ledger info object from manager.
ILedgersManager ledMgr = ss.GetService<ILedgersManager>();
ILedgerInfo ledgerInfo = ledMgr.GetLedgerForOrder(orderGuid);

// If you need heavy-weight legder then do this next.
IOrderLedger ledger = (IOrderLedger)lm.GetLedger(ledgerInfo);

Sorry, I should have been more clear with the code snippet.

The ledger is being accessed directly from the ProTrust tab, so we do not have the order.
The included code was meant to be an example of an equivalent operation for the order in the ProForm tab.

Include a code snippet for what you do have so I have a starting point for your question.

How about this?

Code: Select all

// From inside a shell package OnInitialize method
// This code will be hit on the initial load and when opening/changing tabs
var manager = GetService<IWindowManager>();
manager.ActiveDocumentChanged += (sender, e) => // Standard event args
{	
	var order = _windowManager.ActiveDocument.GetProperty("Order") as IOrder;
	if (order != null) 
		MessageBox.Show("The selected tab is an order!");

	var ledger = _windowManager.ActiveDocument.GetProperty("Ledger") as ILedger; // this does not work
	if (ledger != null)
		MessageBox.Show("The selected tab is a ledger!");
};

(I originally posted that we don't support this. Then another dev gave me the answer...)

You need to subscribe to the "IWindowManager.ActiveDocumentChanged" event. Then in the handler, you can request properties that are specific to the type of window you are handling. The ledger windows allow you to get the guid for the current ledger.

Code: Select all

IWindowManager wm = GetService<IWindowManager>();
IWindowFrame window = wm.ActiveWindow;
if (window != null)
{
    var prop = window.GetProperty("LedgerId");
    if (prop != null)
    {
        Guid ledgerGuid = (Guid)prop;
        string ledgerName = (string)window.GetProperty("LedgerName");
    }
}
