c# - How to share data between forms?

Question

Consider two forms: form1 and form2

form1 calls form2:

form2 frm = new form2()
frm.show

form2 shows a grid with data. When data is selected, it's put into a textbox.

I need the return value from form2 to form1 when it's closed.

How can this be done?

Answer 1

Add a public property to your Form2 class that returns the selected item.

Then, replace the Show() call with ShowDialog() (a blocking method) and check the property afterwards.

Also, rename your forms.
