Here's how to FORCE SEND KEY in NINJA with focus on Chart Window

[Entwaze]

Hello Fellow Ninjas,
Everyone wants to send a key,
but
No one wants to use Windows.Forms
Use this: (Replace ESC with your key and use where you need it, obviously)

var MAIN_WINDOW = System.Windows.Window.GetWindow (ChartControl); // Assuming ChartControl is a reference to the chart panel or control

if (MAIN_WINDOW != null)
{
MAIN_WINDOW.InputBindings.Add (new KeyBinding (ApplicationCommands.Close, new KeyGesture (Key.Escape)));

try
{
MAIN_WINDOW.CommandBindings[0].Command.Execute (null);
}
catch (Exception ex)
{
// Handle any exceptions
Console.WriteLine (ex.Message);
}

MAIN_WINDOW.InputBindings.Clear ();
}
✌

This may be a better way to force recalc with F5 possibly. The issue with the usual way is that it only works if the window is the focused one, and if you focus it, but you have a lot of them open, there can be complications. For instance, imagine someone is typing on a different window when this happens. For an example of how it's done in the usual way take a look at the download "Rollover Indications" by NinjaTrader_ChelseaB.

I had to beat it out of ChatGpt lol

I tried my best to get this to work but just couldn't. After implementing this code above, I received a threading error so I tried using

ChartControl.Dispatcher.InvokeAsync(new Action(() =>.

Is that necessary? This made the error message disappear but did not result in the anticipated action. Any help would be much appreciated.

Hello Taggart,

When working with the UI you do need to use the dispatcher invoke async because that is a cross thread operation.

The control you are trying to target would need to be in focus to send keyboard events to it. You can see the following indicator that sends keyboard commands to the chart and shows how to focus the elements. Take a look at the RolloverBtn_Click method for an example. If you are using that type of code from other areas like OnBarUpdate you would want to use a dispatcher, that script does not use a dispatcher because the code is activated from a UI button.

As a side note some keyboard keys are already mapped and may not be able to be used without addition logic using previewkey events and handling those events.

Oh, ok. I misunderstood this post, thinking that this code would handle the focus issue programmatically.
