Question

I have a project with 3 forms and 10 user controls. Each of these components has around 10 buttons. I would like to use an event to apply a style when they are hovered by the u

Answer 1

You could use a recursive method and call it on your form. It will go through all the child controls of your form, and their children, and if they are a button, it will link them to your centralised method.

Here's an example with a Click event, but it could apply to anything:

    private void RecursiveClickSubscribe(Control c)
    {
        if (c is Button)
        {
            c.Click += GenericClickHandler;
        }
        foreach (Control child in c.Controls)
        {
            RecursiveClickSubscribe(child);
        }

    }

    private void GenericClickHandler(object sender, EventArgs e)
    {
        // stuff you want to do on every click
    }

    Form myForm; // one of your three forms.
    RecursiveClickSubscribe(MyForm);
