While working on how to connect the filters together, I noticed that the clear button can gets the later part of the CompositeFilterDescriptor stuck in the grid.
Reproducible example: https://blazorrepl.telerik.com/wzuRPRvB00Vlj1Ac28
With the current configuration of the repl, filtering using only the TelerikCheckBoxListFilter and clicking filter will filter the column as expected, and clicking clear will blank out the checklist but won't reset the grid's filtering from those checkboxes until after ticking a checkbox and clicking filter, then unticking all checkboxes and clicking filter again. If the checkbox gets used then the clear button gets clicked, clicking the filter button after using the TelerikFilter without any checkboxes checked will filter based on the checkboxes the grid remembers ANDed with the new values from the TelerikFilter, again until the checkbox gets used and then manually emptied without using the clear button.
If the order of _textFilterValueInternal and _checkFilterValueInternal in the FilterDescriptors list get reversed, then the grid's filter memory issue gets transferred to the TelerikFilter meaning the issue is presumably with the grid itself. Also, if you use one or more values in both filters, then the clear button works as intended if there weren't already filters stuck inside the grid.
The clear button works as expected if filtering with both the filter and the checklist before clearing the filter.

Start:
Check some boxes:
Filtered:
Open filter menu and click "Clear":
Re-open the filter menu:
New filter:
Click "Filter":
Re-open filter menu:
Click "Clear" button again:
Hi Nadezhda,
Thanks for your feedback and follow-up. I still have a few comments for which I'd really appreciate a corresponding explanation. If you need further explanation or screenshots on any of these items please let me know. Thanks in advance.
1. Filter seems to work until you click the Clear button.
I think the reason the filtering works in my example is because the context's filter is already using a CompositeFilterDescriptor, so adding more layers of CompositeFilterDescriptor, like how the TelerikFilter element works when using groups, would already have to be supported at the grid level. By the time all the column contexts get combined for filtering the grid, the grid likely doesn't care how many layers of CompositeFilterDescriptor there are.
2. Clear button does not seem to work as it is supposed to work.
As with many other tools, I would have expected the "Clear" button to just overwrite the context's filter descriptors back to the default state, regardless of the current value in the context, which does not seem to work. Especially considering what is mentioned in 1, a reset button should not care about the current state of the values it is clearing.
3. Example's behavior don't match between your version and my version.
From your earlier feedback "...also noticed that when you open the Filter menu with filters already applied, the corresponding checkboxes are not checked."
This is not the case for the example I shared with you. I think it works that way in your version of the example because you didn't remove the parsing logic when you changed what variable is assigned to the TelerikCheckBoxListFilter. Also, directly passing the context to the TelerikCheckBoxListFilter doesn't help me to solve my original problem of trying to rebuild a mixed filter menu that has the checklist AND the default textual filter options on the same column.
4. Existing Telerik reference material.
The SilverLight documentation where you could set the filter menu as 'text fields', 'checklist' or 'both' got removed, but the 'both' option I am trying to create looked something like the below examples from other Telerik libraries which makes me think that this version of Telerik should at least let me recreated the behavior that I need. Please see documentation below.

Hi Jared,
Thank you for providing detailed information for the scenario and example runnable code!
By design, the "Clear" button in the filter menu clears the filter descriptors from the Grid's state. The fact that it is not clearing the filters properly tells me that there is some issue with the filter descriptors in the state.
I observed the state changes when filtering to see how the filters are applied with your current configuration. I noticed there is a discrepancy between the structure that the Grid expects its filter descriptors in and the structure of the custom filter descriptors:
I cannot confirm why the filtering works with your current configuration but the structure of the filter descriptors in the Grid state is not correct and I believe this is why the Grid cannot clear them upon "Clear" button click.
If you update the MixedFilterMenu component so that the CheckBoxListFilter in it works with the CompositeFilterDescriptor filter that comes from the context, then the correct structure of FIlterDescriptors is created and filtering and clearing work properly.
Here is the updated sample: https://blazorrepl.telerik.com/czaHcYFR394XhHZT46.
Having the above in mind, it looks like there no such bug in the Grid, so I updated the status of the item.

Side note:
I also noticed that when you open the Filter menu with filters already applied, the corresponding checkboxes are not checked. Here you may find how you can propely configure the CheckBoxListFilter: https://www.telerik.com/blazor-ui/documentation/components/grid/filter/checkboxlist#custom-data
