c# - How to add a form load event (currently not working)

Question

I have a Windows Forms form where I am trying to show a user control when the form loads. Unfortunately, it is not showing anything. What am I doing wrong? Please see the code below:

AdministrationView wel = new AdministrationView();
public ProgramViwer()
{
    InitializeComponent();
}


private void ProgramViwer_Load(object sender, System.EventArgs e)
{
    formPanel.Controls.Clear();
    formPanel.Controls.Add(wel);
}

Please note I added the load event based on what I read in this article:

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!
