Hello, is there a way to add a custom filter function, "in" for example to the list of filter functions in the radfilter?

Thanks,

Hi Maria,
Thanks for the reply. I want to keep the existing Filter Functions (not rename them), and add a new one called In(Similar to SQL In)

Hello Phani,

Unfortunately the required functionality could not be achieved with RadFilter control. Currently the only possible customization is presented in the previously provided topic.

All the best,

I saw that this post is from 5 years ago, so I was wondering if anything has changed with the RadFilter functionality.  Is it still not possible to add custom filter functions in addition to the existing ones?

Hello Austin,

As I have mentioned in the support ticket that you have opened with the same question, it is possible to override existing filter function, but it is not supported to add new ones:
