Dreamweaver does not give a simple way for binding the checked value for a check botx to dynamic data, you sort of have to do it manually.
In Design view, select the checkbox, then in the property inspector, hard code the initial value to 1. This will add value="1" to the checkbox code. with the checkbox still selected, go to split view, select the 1 in the value, then go to the bindings panel and select the ID column and click the insert button. This will replace the 1 with the dynamic data binding for the ID column.
If you are still having problems, please send a copy of your page so I can examine the code.
