Inputting text to an indicator

[HandsFreeTrader]

One of my indicators has a custom menu to toggle different properties

The toggles all work great however I'm having issues in trying to get a text input and wondering if you have any suggestions

The issue: when I select the text box and try to edit it, if I type any key NT takes over and thinks I'm trying to load a new data series or Instrument.

When I add a NTMenuItem to another NTMenuItem I get the multiple levels, but I've tried adding the following to the NTMenuItem with no luck on registering the key presses

TextBox() - NT window grabs key press before it can (space and backspace key work without issue)

QuantityUpDown() - using the up down I can get a value but this isn't a reasonable solution

NumericTextBox() - gets errors when trying to edit text
"Unhandled Exception: Object reference not set to an instance of an object"

Hello HandsFreeTrader,

Thank you for writing in.

In order to prevent the chart's text box for loading a new instrument or time period to appear while trying to type into your text box, you'll need to create an event handler method.

As an example:

private void TextBox_KeyDown(object sender, KeyEventArgs e)
{
     e.Handled = true;
     TextBox textBoxSender = (TextBox)sender;

     textBoxSender.Text += e.Key;
     theTextBox.SelectionStart = theTextBox.Text.Length;
}

You'll then need to subscribe to this event handler method with your text box's KeyDown event.

As an example:

private TextBox theTextBox;

theTextBox = new TextBox();
theTextBox.KeyDown += TextBox_KeyDown;

The event handler method will prevent the chart's text box from appearing.

Ensure to unsubscribe in State.Terminated with -=.

Please, let us know if we may be of further assistance.

Thanks the KeyDown saved me as I had tried others such as input and textchanged but not KeyDown.
