Filtering in UltraGanttView
posted

Is it possible to use row filtering in the grid of UltraGanttView as follows:

var grid = ultraGanttView1.GetType().InvokeMember("grid",
System.Reflection.BindingFlags.GetField | System.Reflection.BindingFlags.Instance |
System.Reflection.BindingFlags.NonPublic, null, ultraGanttView1, null) as
Infragistics.Win.UltraWinGrid.UltraGrid;


grid.DisplayLayout.Override.FilterUIType = FilterUIType.FilterRow;

As a result of this code, a row appears in the grid to filter, but when I try to click on a cell of this row, an error occurs:

System.NullReferenceException:
