C1.C1Preview.DataBinding.DataSetField.Expression

Expression Property

Expression

Gets the Expression used to calculate the value of the current field.

If this expression is not empty, the field is a calculated field (as opposed to a data field).

Declaration

public Expression Expression { get; }

Remarks

This property is never null (Nothing in VB), it always returns an Expression object, which has empty Text by default. (A non-empty Text string indicates a calculated field.)

To specify an expression, set its Text property, or the ExpressionText property on the current field.

Either this property or DataField, but not both, should be defined on a DataSetField. In case both properties are defined, DataField is used, and Expression is ignored.
