Question by count23 · Aug 12, 2017 at 12:52 AM · events

How do you get text from a modal window between clases?

I'm trying to pass data between two classes in C# and trying to work out best practice.

I have my UI class which has a reference to my data handler class listening for an event "TextRequired".

When text required is called, the UI manager will produce a modal window with the text request. Once it's done, the event will return the "string textfieldinput" to the data handler class for processing.

Is this the correct way to implement this? Should I be encapsulating the returned data in eventargs? Is there a better way to send the data from the UI class to the data handling class?

This may help clear up my issues.

I have the data class as an array of strings. It has methods for "add", "search", "remove" and "get".

In my UI class, i thas a "Createwindow" method that takes a text input and has listeners .

What exaclty is the appropriate method once the "send" button event is invoked, to send the inputfield to the other class's add method?

The only method i can come up with so far is to have an explicit reference to the data class from the UI that says "dataclass.add(inputfield.text)", but this also means that i have dependancies between my data class and UI that shouldn't need to be there.

The only thing i could think of was the UI to have an explicit reference to the data class and the data class throws an event, "add data", listening for a return vale from teh event. but i'm told that events should not be used to return data like that.

Is that the correct implementation?
