C#

//filter 1
//part 1
ViewFilterColumnInfo customFilterDate = new ViewFilterColumnInfo();
customFilterDate.ColumnName = "colOrderDate";
customFilterDate.FilterString = "IsOutlookIntervalLastWeek([OrderDate])";
customFilterDate.Type = DevExpress.XtraGrid.Columns.ColumnFilterType.Custom;
//part 2
ViewFilterColumnInfo customFilterCountry = new ViewFilterColumnInfo();
customFilterCountry.ColumnName = "colShipCountry";
customFilterCountry.FilterString = "[ShipCountry] = 'USA'";
customFilterCountry.Type = DevExpress.XtraGrid.Columns.ColumnFilterType.Custom;
//combine parts
ViewFilterInfo CustomMruFilter1 = new ViewFilterInfo();
CustomMruFilter1.ColumnsFilter.Add(customFilterDate);
CustomMruFilter1.ColumnsFilter.Add(customFilterCountry);

//filter 2
//part 1
ViewFilterColumnInfo customFilterDate2 = new ViewFilterColumnInfo();
customFilterDate2.ColumnName = "colOrderDate";
customFilterDate2.FilterString = "IsThisMonth([OrderDate])";
customFilterDate2.Type = DevExpress.XtraGrid.Columns.ColumnFilterType.Custom;
//part 2
ViewFilterColumnInfo customFilterCountry2 = new ViewFilterColumnInfo();
customFilterCountry2.ColumnName = "colShipCountry";
customFilterCountry2.FilterString = "[ShipCountry] = 'Canada'";
customFilterCountry2.Type = DevExpress.XtraGrid.Columns.ColumnFilterType.Custom;
//combine parts
ViewFilterInfo CustomMruFilter2 = new ViewFilterInfo();
CustomMruFilter2.ColumnsFilter.Add(customFilterDate2);
CustomMruFilter2.ColumnsFilter.Add(customFilterCountry2);

gridView1.ActiveFilterString = "[ShipCity] = 'London'";
gridView1.MRUFiltersInfo.Add(CustomMruFilter1);
gridView1.MRUFiltersInfo.Add(CustomMruFilter2);
