Add distinct values to column filter

[Martin]

 

I know that it is possible to remove distinct values from the filters, as described in this article: https://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-display-all-distinct-values

But I want to add distinct values to the column filter. The use case would be when the user is creating a favorite for a specific set of filters. When the user comes back later to the list, it may not contain the values that the favorite filter had specified at that moment. But the user would like to still be able to see what the filters for the favorite looks like.

Is it possible to add distinct values to a column filter, without creating a custom filter editor?

Hello Martin,

Thank you for the referenced article. 

The distinct values are meant to display the values of the property in the corresponding column for all of the objects shown in the RadGridView.

With this in mind, if you want to extend the functionality of the FilteringControl, the best approach would be to customize it.

I hope you find this helpful.
