Question

I have a simple button which will open up the AddStation form (this button is placed on the MainForm form):

var AddStation = new AddStation();
AddStation.Show();

It shows the form fine, however the form AddStation has a save button. When this button is pressed the AddStation form is closed, but I want to run a method which is in the MainForm‘s class (to update a listbox which is present on MainForm).

This isn’t possible the way I do it right now, since the form AddStation doesn’t have a reference to the MainForm, but how will I do this? How can I run the method MainForm.UpdateListBox from the AddStation form?

Answer 1

I believe it was Dunsten who deleted his answer, but worked perfectly.

I added

public MainForm mainForm;

on top of my AddStation class, then when calling the form I used this:

var AddStation = new AddStation();
AddStation.mainForm = this;
AddStation.Show();

and now I’m able to access methods / objects from AddStation (which I was after)!
