[arma]

How to use local data for combobox in editable data grid ? I have an array data variable that needs to put to combobox.

<th field="username" width="150" align="center" data-options="
                    editor:{
                    type:'combobox',
                    options:{
                    valueField:'username',
                    textField:'fullname',
                    data: [putting js variable array here does not work],
                    required:false
                    }
                    }">User</th>

<scriptt>
var mydata = [{some:data},{another:data}];
</script>

SOLVED.

Instead of using data-options attribute in <th>, i've changed it to use js code. So local data can be assigned from variable.
