Know the answer? Post it — somebody with the same question will find it here.

protected void Page_Load(object sender, EventArgs e){
for (int i = 0; i < CheckBoxList.Items.Count; i++){
CheckBoxList.Items[i].Selected = true;}
}

To set CheckBox:

 CheckBoxName.SetCurrentValue(CheckBox.IsCheckedProperty, true);

To unset CheckBox:

 CheckBoxName.SetCurrentValue(CheckBox.IsCheckedProperty, false);
