Controlling column readonly attribute with Javascript

[German]

Hi, What would be the correct approach to control readonly attribute with Javascript? I actually have an Option group that define a set of readonly attributes of a grid. For example:

Grid: ColumnA
ColumnB
Column C

OptionGroup:
Option1
Option2

If Option1 => ColumnB.readonly(true) / ColumnC.readonly(false)
if Option2 => ColumnB.readonly(false) / ColumnC.readonly(true)

How can I accomplish this scenario? What would be the API to access property ReadOnly of a given column?
Thanks in advance

Ok, after several days trying to work this out, I finally made it work. Here's the code I used:

$("#optionEditA").click(function () {
    var grid = $("#sampleGrid").data("t-grid");
    var columnA = grid.columnFromTitle("ColumnA");
    var columnB = grid.columnFromTitle("ColumnB");

    columnA.readonly = false;
    columnB.readonly = true;
});

$("#optionEditB").click(function () {
    var grid = $("#sampleGrid").data("t-grid");
    var columnA = grid.columnFromTitle("ColumnA");
    var columnB = grid.columnFromTitle("ColumnB");

    columnA.readonly = true;
    columnB.readonly = false;
});

I'm sure there are other ways (more efficient) to make this work but for now this helped me.

Hope it helps someone else
