How to change filter from object to string

Answer 1

Assuming you are writing JavaScript code in a web page and want to convert the filter data to a string suitable for sending or saving, you can use transport.parameterMap to convert filters to a string.

const grid = $("#grid").data("kendoGrid");
const parameterMap = grid.dataSource.transport.parameterMap;
const filterString = parameterMap({filter: grid.dataSource.filter()}).filter

On the MVC side you can then use Kendo.Mvc.Infrastructure.FilterDescriptorFactory.Create(string) to parse the string.
