RecordFiltersLogicalOperator Property

Specifies whether filter conditions across fields are to be combined using logical 'Or' or 'And'. Default is resolved to 'And'.
Syntax
'Declaration
 
Public Property RecordFiltersLogicalOperator As Nullable(Of LogicalOperator)
public Nullable<LogicalOperator> RecordFiltersLogicalOperator {get; set;}
Remarks

RecordFiltersLogicalOperator property specifies how record filters across fields are to be combined. ‘Or’ means only filters of one field are required to pass in order to filter the record. ‘And’ means filters of all fields are required to pass in order to filter the record. The default 'And' which means that filters of all fields are required to pass in order to filter the record.

Example
The following code sets RecordFiltersLogicalOperator to Or to have filter criteria accross fields or'ed instead of and'ed. It filters records so the records with Price of less than or equal to 0 OR Quantity of less than or equal to 0 are displayed.
