MouseLeftButtonDown for TextBox()

[warpinator]

I have a half-transparent text box that on top of a few candle bars, what I am trying to do
is getting mouse x,y location (price levels and date/time) when I click inside the text box
(because those candle bars are still visible under the half transparent text box)

Wonder if TextBox() mouse events would achieve this? Sorry, I am really new to C#

I managed to handle keyboard events inside the text box and get the correct key values,
by following NinjaTrader_Matthew's code:

I am trying to do the same thing for mouse events, but it didn't work.
textBox.MouseLeftButtonDown += TextBox_MouseLeftButtonDown;

The error message:
The name "TextBox_MouseLeftButtonDown" does not exist in the current context

I hope support team could give me some directions or sample codes.

Thanks so much!

Hello warpinator,

I'm not sure what you're trying to achieve with this description. Are you looking to get prices for bars specifically located behind the text box? If so that wouldn ot be possible, the textbox is a WPF control which will be on top of the bars and prevent your mouse from interacting with the chart behind it.

Hi Jesse,

Thanks so much for your reply, is it possible to get X, Y coordinates when I click inside the Text Box?

I managed to get X, Y coordinates when I hover the mouse over Text Box, by following this example:

Hello warpinator,

Not that I am aware of, when you click inside the control that gives focus to the text box. That is not a chart or area which has X/Y coordinates associated with the chart behind it, that is a WPF text box for text entry. You could move the textbox out of the chart to the toolbar or a different area so it's not in the way of where you are trying to click.

Hi Jesse,

Thanks for your reply, I will move the Text Box away from the area I need to click.

Just one last question, since the Text Box is not at fix location (based on price actions), is it possible
I would be able to detect that the mouse click is inside Text Box? (a boolean value would be perfect)
so I can give myself an alert, I would forget to move the Text Box away at heat of moment when market
is crazy.

Thanks so much Jesse !

Hi Jesse,

Another thought regarding my last reply (post #5):

If there's a way to detect whether the cursor is entering the
Text Box or leaving, that will help a lot too.

Thanks !

Hello warpinator,

These items are not specific to NinjaScript but instead for WPF controls. You can find samples of WPF topics by searching online. For mouse events on controls, you can use the preview mouse events like PreviewMouseUp or PreviewMouseDown.

I would be unsure if there is a way to detect the mouse entering or leaving, but you can use the PreviewMouseMove event to see movement over the control.
