Example

Following code shows how to enable row filtering as well as filter rows in code. It adds multiple conditions on a single column to filter rows. It shows only rows with Unit Price greater than 5 and less than 10.

Remarks

The FilterLogicalOperator enum is used for specifying the ColumnFilter's ColumnFilter.LogicalOperator and ColumnFiltersCollection's ColumnFiltersCollection.LogicalOperator properties.
