AndAnd logical operator
OrOr logical operator
Remarks

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

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.

Imports Infragistics.Win.UltraWinGrid

  Private Sub Button10_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button10.Click

      Dim band As UltraGridBand = Me.UltraGrid1.DisplayLayout.Bands(2)

      ' Set AllowRowFiltering to true to allow the user to filter rows. This is not
      ' necessary for filtering rows through code.
      band.Override.AllowRowFiltering = DefaultableBoolean.True

      ' You can enable or disable row filtering on individual columns too.
      ' Column's setting have higher precedence for that column than the band's
      ' override settings.
      band.Columns("Phone").AllowRowFiltering = DefaultableBoolean.False

      ' Set the RowFilterMode off the override to AllRowsInBand so that the
      ' ultragrid makes use of UltraGridBand.ColumnFilters.
      band.Override.RowFilterMode = RowFilterMode.AllRowsInBand

      ' Clear any previous filters on that column.
      band.ColumnFilters("Unit Price").FilterConditions.Clear()

      ' Add two conditions one that requires value be greater than 5 and another
      ' that requires that the value be less than 10. Also we want to And these
      ' conditions because the value must satisfy both conditions. To do that
      ' set the LogicalOperator on the ColumnFilter of that column to And.
      band.ColumnFilters("Unit Price").FilterConditions.Add(FilterComparisionOperator.GreaterThan, 5)
      band.ColumnFilters("Unit Price").FilterConditions.Add(FilterComparisionOperator.LessThan, 10)
      band.ColumnFilters("Unit Price").LogicalOperator = FilterLogicalOperator.And
