Question

I have a listBox that I would like to carry out a method when its loaded up, although I can’t use the Form “On_Load” trigger, since the ListBox is within a TabControl.

Is there a way of getting a method to execute when the object initializes?

As @SLaks stated, you could put in your class’s constructor. However, if what you want to prepare relies on other elements in the form, you can add to the event handler queue at the end of a form loading, but before its actually presented to the user.

In the constructor code of your form (not the designer code), add to the load event, then add your own custom function

public partial class frmYourForm : Form
{
    public frmYourForm()
    {
       Load += YourPreparationHandler;
    }

    private void YourPreparationHandler(object sender, EventArgs e)
    {
        // Do you code to prepare list, combos, query, bind, whatever
    }
}
