TcxGridTableFiltering.ColumnAddValueItems Property

Specifies if value items (fviValue filter conditions) are added to the filter pop-up window.

Declaration

property ColumnAddValueItems: Boolean read; write; default True;

Property Value

Type	Default
Boolean	True

Remarks

+Filter dropdowns are always populated with value items. When a grid View is bound to a large dataset, obtaining value items may take time. To improve performance, prohibit adding value items to the View’s filter dropdowns by assigning False to the ColumnAddValueItems property. The property setting is applied to all column filter dropdowns in the View. To control this functionality in individual columns, use a column’s Options.FilteringAddValueItems property. Values are added to a column’s filter dropdown only if both the ColumnAddValueItems and Options.FilteringAddValueItems properties are set to True.

Handle the View’s DataController.Filter.OnGetValueList event to extend filter dropdowns with required values.

To improve performance when manually populating filter dropdown lists with items, call the TcxGridFilterValueList.Load method and pass False as the AAddValueItems method parameter.

The ColumnAddValueItems property’s default value is True.
