How do I hide the "Custom" option in the filterbar dropdown?

To achieve this, implement a custom filter bar cell that derives the cell model/cell renderer from the GridTableFilterBarCellModel/GridTableFilterBarCellRenderer.

The GridTableFilterBarCellModel.FillWithChoices method is overridden to remove the string Custom from the list.

C#

VB

The GridTableFilterBarCellModel.Select method is rewritten with the Select_withoutcustom method that specifies the index for the selected item. You can pass the index for the Custom selected item as 0.

C#

VB

The GridTableFilterBarCellModel.ListBoxMouseUp() method is overridden to invoke the Select_withoutcustom method instead of the Select method.

C#

VB

A new CellType is created by adding the instance of the derived GridTableFilterBarCellModel class into the GridGroupingControl’s cellmodels.

C#

VB

After applying the properties, the Grid is displayed as follows.
