    Currently, is there a way to compare Kendo filters?

    Example of equalities:
    * {"logic":"and","filters":[{"value":"abc","operator":"eq","field":"type"},{"value":"xyz","operator":"eq","field":"model"}]}
    * {"logic":"and","filters":[{"logic":"or","filters":[{"value":"abc","operator":"eq","field":"type"}]},{"value":"xyz","operator":"eq","field":"model"}]}
    * {"logic":"and","filters":[{"logic":"or","filters":[{"value":"abc","operator":"eq","field":"type"}]},{"logic":"or","filters":[{"value":"xyz","operator":"eq","field":"model"}]}]}
    * {"logic":"and","filters":[{"value":"abc","operator":"eq","field":"type"},{"logic":"or","filters":[{"value":"xyz","operator":"eq","field":"model"}]]}}
    * {"logic":"and","filters":[{"value":"xyz","operator":"eq","field":"model"},{"value":"abc","operator":"eq","field":"type"}]}
    * ...

    There are many ways that Kendo generate equal filter queries (such as the "Clear" button). However, I did not find a way to compare...

    Hello Pascale,

    In general, the best way to compare filters is to perform a deep manual comparison of the filter expressions.

    The exposes a method that could be sufficient to check for changes in the filter state, but please note that it doesn't perform a sophisticated (does not check particular filter expressions) comparison and it could not work in all possible cases.

    Here is a link to the implementation of the method:
