Disable Chart Scroll just when above a Button

[facuevasm]

Hello guys,

I would like to know if there is a way to disable, by code, that ninjatrader 8 goes back on bars when using the mouse wheel. I create a button on chart, that is reacting at the mouse wheel, and making some action, but soon as I place the mouse cursor on the button, it also makes the chart to go back on past bars. and I want to disable that function, only when Im above the button, but not on every other point on the chart.

I hope I could explain what I need.

Thank you!

Hello facuevasm,

Yes you can do that by adding the following code to your control:

textBox.PreviewMouseWheel += (o,e) => { if(e.Delta > 0 || e.Delta < 0) e.Handled = true; };

You can test that code by downloading the following script TestTextBox and using it in the State.Historical logic where the handlers are being subscribed to. You would otherwise replace textBox with the variable of your control in your own script.
