TcxGridCardViewFiltering.RowAddValueItems Property

Specifies whether or not value items (fviValue filter conditions) are added to filter dropdowns.

Declaration

property RowAddValueItems: Boolean read; write; default True;

Property Value

Type	Default
Boolean	True

Remarks

Filter dropdowns are always populated with value items by default. 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 RowAddValueItems property. The property setting is applied to all card row filter dropdowns in the View. To control this functionality in individual card rows, use a card row’s Options.FilteringAddValueItems property. Values are added to a card row’s filter dropdown only if both the RowAddValueItems and Options.FilteringAddValueItems properties are set to True.

Handle the View’s DataController.Filter.OnGetValueList event to manually 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 default value of the RowAddValueItems property is True.
