Winforms Change Label Properties in Usercontrol from Parent Form

I am trying to change the label and text of a label which is inside a UserControl from within a Parent Form method at runtime.

label

text

UserControl

Form

So within the method in parent Form I do the following to change the label properties which is inside a UserControl

Form

UserControl

public partial class Form : Form
{
public void Form_Method()
{
UserControl uc = new UserControl();
uc.UpdateLabel(true);
}
}


And the custom method inside my UserControl

UserControl

public partial Class UserControl : UserControl
{
public void UpdateLabel(bool value)
{
if (value)
{
lbl.Text = "This";
lbl.Forecolor = Color.Green;
}

if (value == false)
{
lbl.Text = "That";
lbl.Forcolor = Color.Red;
}
}
}


However when I navigated to the UserControl the label properties have not changed as I was creating a new instance of the usercontrol on the fly which
technically disappears after the method ends.

UserControl

new

So I tried creating a public property of the actual UserControl as follows

UserControl

public partial class Form : Form
{
public UserControl _uc;

public void Form_Method()
{
UserControl uc2 = new UserControl();
uc2.UpdateLabel(true);
_uc = uc2;
}
}


However it has no effect whatsoever? I have come across info of using Events or Delegates am not sure if they are the correct process for what am trying to do?

Events

Delegates

Controls

this.userControl1.UpdateLabel(true);

form2.UserControl1.UpdateLabel(true);
