Hello, let me show you some screenshots to describe better what I mean.
I have the following grid

This is database / xml driven. At the end of every record I have some checkboxes, witch they define in witch quarter a project belongs.
So far, so good.
But when it comes to edit there is the following problem

As you can see all the checkboxes are always empty. This is because when I define them I don't know how to say (“make this check box been checked by default”). For example when I define an input field I can do this in the javascript file
{name:'sector',index:'sector',width:50,editable:true,edittype:”select”,editoptions:{value:””}},
How can I set a checkbox to start by default checked?
{name:'q1',index:'q1',width:37,align:'center',editable:true,edittype:”checkbox”,
editoptions:{value:”1:0″}},
p.s. I am almost sure that I use totally wrong way to succed what I want to do!
p.s.2 Really sorry, I know that I am starting to becoume really annoing, but I have to finish a project and I really don't have any idea how to do that!
p.s.3 thanks again and again and again.
