Dear, Stefan
Thank you for the answer, of this case and i want to ask you about set data type in multi column header.
In my grid, i set data type 'number', but when i want to edit the data, the data type is still 'string'. I set data type like this :
{
title: "Retail Sales Total 1",
columns: [{
title: "Actual",
field: "parameter[0].targetDealer.actual",
width: 80,
type: 'number'
}, {
title: "Plan",
field: "parameter[0].targetDealer.plan",
editable: function () {
return false;
},
width: 80,
type: 'number'
}]
}
Thank you
