Updating UI of another form

[lucaoscar]

Hi all,

as you can see from the level of my question, i am pretty new to c# and
programming in general.

situation: i would like to update the UI of a form (main form of my
application) from a second form (which was called from the first).
Ideally when a button on the second form is pressed, the first one
(main form) should update/refresh its UI.

But it would be also fine to have the first form refreshing when the
second form is closed/disposed.

Can you help me please? Thanks in advance.

Luca

Try adding an event to the second form and catching it in a handler on the
first form. Hook up the handler after creating the second form but before
showing it.

Hi,

There are several ways of doing this:

- Pass a reference to the first form in the constroctor of the second. then
you should declare some public methods in Form1 they will do the update on
it, this method will be called from Form2.

- Make Form2 declare some events that Form1 can subscribe to and update its
UI as needed.
