Dear Dimiter,
As it is not possible to initialize a compare js function when using a MVC Wapper is it possible to add on after the page loads. With js and by calling the kendoGrid object .
var grid = $("#myGrid").data("kendoGrid);
grid.columns["ProductiName"].columns.sortable.compare = myfunction or functionfunction(){}
or
grid.columns[0].columns.sortable.compare = myfunction or function(){}
Yours,
Ariel
