AtmStrategySelector is an UI element users can interact with for selecting ATM Strategies.
Cleanup() |
Disposes of the AtmStrategySelector (Note: calling the NTTabPage base.Cleanup() is sufficient to clean up this control) |
CustomPropertiesChanged |
Event handler for when properties have changed on the ATM strategy |
Id |
A string identifying the ATM Strategy selector |
SelectedAtmStrategy |
Returns an AtmStrategy representing the selected ATM strategy |
SelectionChanged |
Event handler for when the selected ATM strategy has changed |
This example demonstrates how to use the ATM strategy selector and properly link its behavior with the quantity up/down and TIF selectors.

private void OnAtmCustomPropertiesChanged(object sender, NinjaScript.AtmStrategy.CustomPropertiesChangedEventArgs args) { // Adjust our TIF and Quantity selectors to the new ATM strategy values tifSelector.SelectedTif = args.NewTif; qudSelector.Value = args.NewQuantity; }
// NOTE: Don't forget to clean up resources and unsubscribe to events // Called by TabControl when tab is being removed or window is closed public override void Cleanup() { // Clean up our resources } |
