How to get & set mvc grid readonly cell value

[veerendra potru]

I have a telerik mvc grid with 3 fields and the first 2 are editable.

columns.Bound(x => x.FirstName).Width(120)
columns.Bound(x => x.LastName).Width(120)
columns.Bound(x => x.FullName).Width(120).ReadOnly(); 
.Editable(editing => editing.Mode(GridEditMode.InLine))
.ClientEvents(events => events.OnEdit("onRowEdit"))

Suppose on edit mode, if i make changes for FirstName and LastName I coluld be able to update the FullName filed if it is not readonly(means FullName also need to be editable) with the following code:

function onRowEdit(e) {
        $("#FirstName ').('blur', function () {
          Common();
        });
        $("#LastName ').('blur', function () {
            Common();
        }); 
function Common()
{
$("#FullName").get(0).value   = $("#FirstName").get(0).value + $("#LastName").get(0).value ;
}

The above code works if the FullName field is not readonly. But the FullName filed should be readonly. Any workaround is much appreciated.
Thanks,

Perhaps you should not make the column readonly.. rather set its disabled attribute to true
