A
CheckBoxList
will, perhaps unsurprisingly, produce a list of
CheckBox
controls. It won't let you add other controls within each item in the list.
I'd suggest using a
ListView[
^] instead.
I'd also recommend against using a checkbox to delete the row. That's not the expected behaviour for that control. It would be better to use the checkbox to indicate whether the item is completed, and a button to delete the item.
