Definition

AccountSelector can be used as an UI element users can interact with for selecting accounts.

 

Events and Properties

Cleanup()

Disposes of the AccountSelector (Note: calling the NTTabPage base.Cleanup() is sufficient to clean up this control)

SelectedAccount

Returns an Account representing the selected account

SelectionChanged

Event handler for when the selected account has changed

 

 

 

Examples

C#


/* Example of subscribing/unsubscribing to market data from an Add On. The concept can be carried over

to any NinjaScript object you may be working on. */

public class MyAddOnTab : NTTabPage

{

    private AccountSelector accountSelector

 

    public MyAddOnTab()

    {

        // Note: pageContent (not demonstrated in this example) is the page content of the XAML

        // Find account selector

        accountSelector = LogicalTreeHelper.FindLogicalNode(pageContent, "accountSelector") as AccountSelector;

 

        // When the account selector's selection changes, unsubscribe and resubscribe

        accountSelector.SelectionChanged += (o, args) =>

        {

            if (accountSelector.SelectedAccount != null)

             {

                // Unsubscribe to any prior account subscriptions

                accountSelector.SelectedAccount.AccountItemUpdate -= OnAccountItemUpdate;

                  accountSelector.SelectedAccount.ExecutionUpdate -= OnExecutionUpdate;

                accountSelector.SelectedAccount.OrderUpdate -= OnOrderUpdate;

                 accountSelector.SelectedAccount.PositionUpdate -= OnPositionUpdate;

 

                // Subscribe to new account subscriptions

                accountSelector.SelectedAccount.AccountItemUpdate   += OnAccountItemUpdate;

                  accountSelector.SelectedAccount.ExecutionUpdate     += OnExecutionUpdate;

                  accountSelector.SelectedAccount.OrderUpdate         += OnOrderUpdate;

                 accountSelector.SelectedAccount.PositionUpdate      += OnPositionUpdate;

             }

        };

    }

 

    // Called by TabControl when tab is being removed or window is closed

    public override void Cleanup()

    {

        // Clean up our resources

        base.Cleanup();

    }

 

    // Other required NTTabPage members left out for demonstration purposes. Be sure to add them in your own code.
