User Control Eventhandler. How to get my control's components to inherit an Eventhandler.

I have a User Control called BoxButton that I want to behave like a Button, I want my PictureBox and TextBox to call or invoke BoxButton.Click.

some things I've tried include: Doesn't work with windows designer code due to syntax, I have to manually type BoxButton.Click = BoxButton_Click rather than BoxButton.Click += BoxButton_Click.

public new EventHandler? Click
{
    set
    {
        Picture.Click += value;
        TextBox.Click += value;
        base.Click += value;
    }
}

public new EventHandler? Click
{
    set
    {
        Picture.Click += value;
        TextBox.Click += value;
        base.Click += value;
    }
}

Doesn't work :<

private void picture_click(object sender, EventArgs e) => this.Click += picture_click;
private void text_click(object sender, EventArgs e) => this.Click += text_click;

private void picture_click(object sender, EventArgs e) => this.Click += picture_click;
private void text_click(object sender, EventArgs e) => this.Click += text_click;

something like this also doesn't work

public BoxButton() : base()
{
    InitializeComponent();
    Picture.Click += this.Click;
    TextBox.Click += this.Click;
}

public BoxButton() : base()
{
    InitializeComponent();
    Picture.Click += this.Click;
    TextBox.Click += this.Click;
}

Error CS0079 "The event 'Control.Click' can only appear on the left hand side of += or -="

So you want a button with an icon and, i assume, some text that the user can't type into?

no it's readonly and only for display, label doesn't dock properly so I use a textbox but yeah pretty much, that's what I want.
