Parameters

Type	Description
GridCustomizeFilterRowEditorEventArgs	An object that contains data for this event.

Remarks

The Grid generates and configures cell editors for individual columns based on associated data types. You can use the EditSettings property to customize a column’s editor settings. The Grid displays these cell editors in the filter row and in data rows during edit operations.

Handle the CustomizeFilterRowEditor event to customize filter row editors separately from data row editors.
