The dialog appears when you click Insert > Web Controls > Filter Control on the menu bar, drag Filter Control from the Toolbox panel, or click the down arrow on the Insert Control Objects button 
and select Filter Control from the drop-down list. It helps you to insert a filter control into a report for filtering component data. See the dialog.
The following are details about options in the dialog:
Select Fields
Specifies the fields to bind to the filter control. All the selected fields should be of the same data type. All uncomparable data type fields cannot be bound to filter controls, such as Binary, Blob, Clob, Longvarchar, Longvarbinary, and Varbinary.
The common usage is to select one field, and then based on the field to filter the data of the components created from the same data source as the field.
To filter components using different data sources, choose a common field all the data sources contain and select the field in all the data sources.
Apply To
Specifies the target data components you want to apply the filter to. The drop-down list includes all the data components in the current report that are based on the same data sources the selected fields are in.
OK
Inserts the filter control into the report and closes the dialog.
Cancel
Cancels the operation and closes the dialog.
