i have an arraylist containing a nu 1

[seanbo]

i have an arraylist containing a number of 'NodeInfo' objects. node info is made up of some primatives, and a windows component i designed called 'PreviewBox'.

preview box extends PictureBox. it is a dragable and resizable item that displays certain information relative to my project.

main form > array list of node info > preview box

i want to put a method in the code for my main form, the class that my array list is found within, that is triggered by an event such as my preview box being clicked.

i already have such a method withid preview box, but i don't know how to extend it in main form for every object in an unknown amount of objects. how would i go abou this?

Very simple.
If you choose to write a code for an event raising, you usually double click on the event at the events list, then the editor adds an empty method like:

private void button1_Click(object sender, System.EventArgs e)
{
// here you write the action
}

If you look at the hidden code which it's headline is:

Windows Form Designer generated code

you will see the function:

private void InitializeComponent()

In this function you will see a row like this:

this.button1.Click += new System.EventHandler(this.button1_Click);

The only thing you need is to do it yourself!
I had a similar case where I used an unknown amount of PictureBox created in runtime.
I made this function:

private PictureBox InitPicture(PictureBox pic)
{
    pic = new PictureBox();
    pic.Click += new System.EventHandler(ClickPic);
    pic.MouseHover += new EventHandler(pic_MouseHover);
    return pic;
}

In the main code I had a PictureBox array.
I allocated a new size to the array, and in a for loop I wrote:

pictures[i] = InitPicture(pictures[i]);

So now every PictureBox created will have the behavior as I wrote for the events Click and MouseHover.

Hope it helped you.
