Indeed such a functionality is not available out of the box. However such behavior can be implemented with the help of a RadFilter and RadGrid. The idea here is to group the items by Name and use a RadFilter with an OR RadFilterGroupOperation to filter the grid. Once the data is filtered we can check whether the number of items in the group is equal to the filter expressions count if that is the case this means that the name is the one we are looking for. Following this approach I have assembled a sample website which can be found in attachments.
