Ohhh, I understand now ! You really should read up on "Delegates and
Events". Also, you seem to be using the term "Event" and "routine"
interchangeably, while they are different. An Event is handled by an
Event handler, which is the routine you are referring to. Also, I'm
not discussing the wisdom of having 50 checkboxes on a form (If I
needed them, I'd probably create them dynamically or look into having
another control deliver similar functionality.)
You can attach multiple events to the same handler as long as their
signature is the same. For example, all CheckedChanged events will
have the same signature, so you attach all the events to the same
handler. Assuming that this should be the filter_gen() method, you
will need to change the signature of the method as follows :
---
private void filter_gen(object sender, EventArgs e)
{
}
---
Note that this matches the signature expected of a CheckedChanged
event handler. Now you need to attach all the 50 events to your
filter_gen method. You could do this in two ways :
1. Go to design view and in the Properties window, under the events
section just set the CheckedChanged handler *for each* checkbox to
your filter_gen() method. (Select it from the dropdown). You could do
this in one step by selecting all 50 checkboxes and then setting the
Eventhandler. The wire-up statements illustrated below will
automatically be added by VS to the InitializeComponent() method.
2. Add wire-up statements such as the following for all 50 handlers at
a startup phase of the form or in the constructor:
private void Form1_Load(object sender, EventArgs e)
{
checkBox1.CheckedChanged += new EventHandler(filter_gen);
checkBox2.CheckedChanged += new EventHandler(filter_gen);
checkBox3.CheckedChanged += new EventHandler(filter_gen);
//... and so on till 50
}
I recommend the first option. Let VS do some work !! ;-)
