"click" missing from getOptions() on columns

[Jon]

I am adding a click function to a column containing a button like so

            .Columns(columns =>
            {
                columns.Command(command =>
                {
                    command.Custom("customedit").Click("openScanLines").Text("").HtmlAttributes(new { title = "View Scan Details"});
                }).Width(75);
            })

We have an option to save the grid options to be loaded a later point.  So we use $("MyGrid").data("kendoGrid").getOptions() to get the options on the grid, Stringify it, and save it to a database  Then we pull that JSON string from the database and use $("MyGrid").data("kendoGrid").setOptions(options) to load them. The problem is the "Click" function is always missing from the $("MyGrid").data("kendoGrid").getOptions(), resulting in the Click function no longer working when the option are then set.  What's the deal?  How can I retain the click function for these columns?

EDIT:  it happens during the Stringify

Hello, Jon,

Thank you for the details.

This is expected scenario which is described in our documentation:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid#methods-setOptions

Also, the following KB article is showing a possible approach how this can be resolved:

I hope this is helpful.
