I tried to open the project, but it seems to be bound to the source control. I am not sure if it is because of this, I couldn't open any files!

When I try your approach here, I run into problems with the javascript function to retrieve the associated data value, which is the core problem to be solved:

<script>
    function getParentId() {
        var row = $(event.srcElement).closest("tr");
        var grid = $(event.srcElement).closest("[data-role=grid]").data("kendoGrid");
        var dataItem = grid.dataItem(row);
        return { ProductID: dataItem.ProductID };
    }
</script>

When I try this with the latest incarnation of Kendo grid, I get 'ReferenceError: event is not defined', when $(event.srcElement) is attempted to be evaluated.

I was wondering if you knew of a solution to this issue, or if there is now some better, Telerik-supported way of retrieving associated column values?
