## Description

I have a Telerik UI Data Grid for ASP.NET MVC with regular filters and local filtering. How can I add custom filters and combine the regular filters with the custom ones?

## Solution

To allow the application of both filter types, wrap the custom filter in an additional filter with the `"OR"` criteria.

For the complete implementation of the approach, refer to [this runnable example](https://dojo.telerik.com/AgIgO/17), which applies the [`filter`](https://docs.telerik.com/kendo-ui/api/data/datasource/methods/filter) method of the DataSource.
