TcxCustomGridTableItem.VisibleForExpressionEditor Property

Specifies if the grid View item is available as a value source for expressions in the “Expression Editor“ dialog.

Declaration

property VisibleForExpressionEditor: TdxDefaultBoolean read; write; default bDefault;

Property Value

Type	Default
TdxDefaultBoolean	bDefault

Remarks

This property specifies under which conditions the “Expression Editor” dialog shows the grid View item in the Fields category. Users can still manually type the Caption or AlternateCaption property value enclosed in square brackets to use the item in an expression as a value source.

Options include:

Value	Description
bFalse	The dialog never lists the grid View item as a value source for expressions.
bTrue	The dialog always lists the grid View item as a value source.
bDefault	The dialog lists the grid View item under the Fields category only if the Visible property is set to True.

Note

Call the ShowExpressionEditor procedure to invoke the “Expression Editor” for the grid View item. A procedure call has no effect if the item does not support calculated field expressions.

The VisibleForExpressionEditor property’s default value is bDefault.
