So, few things here. Using the new DataFilter of the Data List. 1) How can I make the contains to be case insensitive? And two, how do I hook into the event that is triggered when clicking on the 'remove filter' buttons so that I can restore the data list to it's pre-filtered state? Once again, not finding any docs on how to hook into these click events.

Looks like you've not tried [our demo](https://blazor.radzen.com/datafilter) - removing or adding filters will result in immediate filtering if the mode is auto. You can also check the component source (there is a link in the demo itself) or you can check the [API reference](https://blazor.radzen.com/docs/api/Radzen.Blazor.RadzenDataFilter-1.html#Radzen_Blazor_RadzenDataFilter_1_FilterCaseSensitivity) or you can even try to use intellisense is Visual Studio.
