Filter Operators

The FilterOperator enum contains all filter operators supported in the Telerik UI for Blazor suite.

Each filter operator is compatible with a specific data type. Always use the correct filter operator during filter customizations. Otherwise, an exception will occur about the assigned DefaultFilterOperator not applicable for the current data type.

ArgumentException: The assigned DefaultFilterOperator ... for the Start column is not applicable for ... type.
