WPF How to set checkbox IsChecked binding in code behind

Question

I have a style that I have to create in code-behind. It has a checkbox that looks like this..

<CheckBox 
              HorizontalAlignment="Center"
              VerticalAlignment="Center"
              IsChecked="{Binding Path=DataItem.IsChecked}"
              >
</CheckBox>

How do I replicate this in code-behind?

Something like this:

CheckBox myCheckBox = new CheckBox();
myCheckBox.HorizontalAlignment = HorizontalAlignment.Center;
myCheckBox.VerticalAlignment = VerticalAlignment.Center;
myCheckBox.SetBinding(ToggleButton.IsCheckedProperty, "DataItem.IsChecked");

myCheckBox.SetBinding(ToggleButton.IsCheckedProperty, "DataItem.IsChecked"); doesn't work. I think its CheckBox.IsCheckedProperty.

IsCheckedProperty is defined in the ToggleButton class. CheckBox is derived from ToggleButton. What exactly doesn't work?

It doesn't recognize ToggleButton as a class. But this works. thanks

var myCheckBox = new CheckBox() {DataContext = DataItem };
myCheckBox.SetBinding(ToggleButton.IsCheckedProperty, new Binding(nameof(DataItem.IsChecked));
