Issue with code in Help

[Mindset]

Hi

Trying to explore AddOn's and in your support pagehere you outline various ideas which are very helpful.
However when I copied the code for the Add Button scenario it comes up with some errors regarding panellength, location and direction.


I wonder if you could help me resolve this?

thank you

Hello Mindset,

If you can provide the specific errors you had received or a .cs file containing the code you copied/pasted that would give a better idea on what the solution is. It may just be that you are missing a using statement.

The code you linked to is also not a full sample, that is an explanation of what is being done in the basic addon sample file from this link: https://ninjatrader.com/support/help...t_overview.htm

The samples in the addon help guide basically all assume that you have used the basic addon sample as a starting point to learn those various parts of the addon framework.

Errors are lines 93 and 111

Hello Mindset,

I tried the code and don't see any compile errors. If you are seeing a runtime error II would need more details on what the specific errors are or what use case was used. It is helpful if you can provide the specific errors you see with the code so that we have a better idea of what you are seeing.

Please let me know if I may be of additional assistance.

[Mindset]

sorry - I commented out the two lines that were the problem - lines 93 and 111. If you uncomment them you get the compile error which is that the name panelLocation, etc don't exist

[NinjaTrader_Jesse]

Hello Mindset,

For the panel Text you would replace that with whatever text you had intended to display.

 TextBlock.Text =  "your text here";

I don't see anything commented for line 93 with the given code, if you are seeing additional errors please post the error message.

Please let me know if I may be of additional assistance.

Hello Mindset,

The variables you are trying to print don't exist, please see my prior post about how to set a custom string of your own. I otherwise don't see an error after making that change for your use case. After making that change if you see an error message please post that instead.


Please let me know if I may be of additional assistance.

Changing the text string doesn't alter the fact that PanelLocation for instance doesn't exist and that's where I need some guidance - what is the code syntax to set a PanelLocation, etc?

Error - the name PanelLocation does not exist in the current context

[NinjaTrader_Jesse]

Hello Mindset,

Those variables don't exist where you tried to use them so that's not valid. You need to replace that with your own string and not use the panel variables as they don't exist.

To set a location of a WPF control you would generally use WPF techniques like setting a grid column or row. Panels are reserved for indicators being displayed in a chart and would not be something you would access with WPF.

Forgive me for being dim but if you put them in a code in the help section shouldn't they exist? If you put code that doesn't compile it doesn't help idiots like me lol.
That's the bit I am really interested in and don't truly understand.

[NinjaTrader_Jesse]

Hello Mindset,

Unfortunately I couldn't comment as I don't know who made that sample, the solution is simply to use your own string here as shown previously.
