Adding custom operators to column filter

[Nicole]

I've been testing the Grid and have been liking what I've seen so far. There is something that I'm getting caught up on at the moment though.

I'd like to add some custom operators to the column filters for certain fields we use. Things like 'between', 'in list' etc. Is there a way to add these options or will we have to create a completely custom implementation of filtering? Thanks.

Hello Joe,

The desired behaviour to add custom operators can be achieved using the filter.operator property of the DataSource and using a custom function:

http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#configuration-filter.operator

More information can be found in similar threads in our forum. They also have some examples:

Please have in mind that this is a custom filter, and adding it as an option in the filter menu is not supported.

If you would like to suggest more filter operators that can be useful, submit a feature request in our UserVoice portal, and based on its popularity we may implement it in a future release:

I hope this is helpful.
