 ## Filtering
 
-The filtering criteria for each filtered field is stored in an individual collection of [`IFilterDescriptor`](/blazor-ui/api/Telerik.DataSource.IFilterDescriptor).

 The `CompositeFilterDescriptor` exposes:
-* [`FilterDescriptors`](/blazor-ui/api/telerik.datasource.compositefilterdescriptor#Telerik_DataSource_CompositeFilterDescriptor_FilterDescriptors) property. This property represents another collection of `IFilterDescriptor`. To access the filtering criteria cast the `IFilterDescriptor` to a [`FilterDescriptor`](/blazor-ui/api/telerik.datasource.filterdescriptor). Each `FilterDescriptor` instance gives access to:
-    * The `Member`—The field where the user filters. Each filter descriptor describes also the `MemberType`, that represents the type of the field.
-    * The `Operator`—The [`FilterOperator`](/blazor-ui/api/telerik.datasource.filteroperator) that applies. There are different operators depending on the `MemberType`. Read more about the [filter operators]({%slug common-features-filter-operators%}).
-    * The `Value`—The user input to filter by.
-* [`LogicalOperator`](/blazor-ui/api/telerik.datasource.compositefilterdescriptor#Telerik_DataSource_CompositeFilterDescriptor_LogicalOperator) property. This property can be either AND or OR. This property represents the logical operator applied between the instances in the `FilterDescriptors` collection.

 When the filtering is initiated, the `CompositeFilterDescriptor` properties get different values, depending on the filter mode:
