Escape Key recognition

[rt-trader]

Hello,

I am attempting to use the Escape Key to abort a drawing action if required using

private void OnKeyDownHandler(object sender, KeyEventArgs e)
{

if (e.Key==Key.Escape)
{
Print("Escape key pressed");
}
}

however this is not being recognized. I have seen on some general C# forums that Escape Key recognition within WPF can be problematic.

Can someone please offer any suggestions on if/how this can be done.

Thank you.

Hello,

Thank you for the question.

I am unsure by the sample on what object you are using for the key event, but I have seen for Buttons using the MouseDown event this does not bubble the event in a chart, so instead the PreviewMouseDown was used.

Can you try using the PreviewKeyDown event instead if available for the object? This may allow you to get the correct keys if you are able to use this event.

I look forward to being of further assistance.

Hi Jesse,

Thank you for the reply and suggestion.

After much trial and error, it seems that the Escape key is not available to NinjaScript (caveat - it should be noted I have limited coding skills.......)

Using the code below I found that the keys not used by NT will print, however it seems that any key used by NT is locked out and not accessible via PreviewKeyDown. This is different to NT7 where the Escape key was available programatically.

public void PreviewKeyDown(object sender, KeyEventArgs e)
{

Print(e.Key.ToString());

}

and in State == State.Historical

ChartPanel.PreviewKeyDown += PreviewKeyDown;

Any suggestions for a work around here so I can use the Escape key?

Thanks
