Does the grid support my replacing/removing the Filter operators?

Some column examples:

Total Sales (dollar format)
Replace filter textbox and operators menu with predefined options of "< 1 Million", "1 to 10 Million", "11 to 50 Million", and "> 50 Million".

Category (text but business rules only allow 3 categories)
So replace filter textbox and operators menu with the 3 categories, e.g. "Fruit", "Bread", "Meat"

Hello Jason,

The RadGridView supports implementing Custom Filtering which would be suitable for this. Please have a look at the documentation here on custom filtering and also at the demos on your PC under GridView >> Filtering >> Custom Filtering

If you need further help, please let me know
Thanks
Richard

Thank you.  I am familiar with custom filtering, but that is not exactly what I am look for.

I have attached a few screenshots of an app that I built using a competitor's grid a couple of years ago.

Hello Jason,

As far as I'm aware, this is not upported, but instead of the custom filtering I suggested before, you could use a Custom Filtering Row. Have a look at the demos under GridView >> Filtering >> Custom Filter Row. This allows you to integrate the custom filtering directly into the grid.

I have started to look at altering the context menu that is produced when clicking on the regular filter section, but at the moment, I don't believe that this will be flexible enough for your needs. If I can figure out how to adapt it for you in a way that I think you will be happy with, I'll let you know.

Regards,
Richard

Hi Jason,

Thank you for writing.

I would second what Richard has already said: we do not support the functionality shown in your screen-shots. Since this is a very specific scenario, you will have to implement it yourself, probably with a custom filter dialog, custom filter button and using Custom Filtering.

All the best,
