ParameterFieldDefinition.ApplyDefaultValues Method

Applies values to the group of default values for a specified parameter in a report.

Namespace CrystalDecisions.CrystalReports.Engine Assembly CrystalDecisions.CrystalReports.Engine (CrystalDecisions.CrystalReports.Engine.dll)

Syntax

'Declaration
Public Overrideable Sub ApplyDefaultValues ( _
    ByVal defaultValue As CrystalDecisions.Shared.ParameterValues _ 
)

public virtual void ApplyDefaultValues (
    CrystalDecisions.Shared.ParameterValues defaultValue
)

Parameters

defaultValue
Contains the default values set for the parameter.

Remarks

The default value set should fall within the scope of the EditMask, MaximumValue, and MinimumValue properties, if set. For more information on edit masks see Limiting Entry Type and Format in Parameters.

Example

The following example sets the current values for a ranged parameter, sets the default value for a discrete parameter, and sets the minimum and maximum values for a discrete parameter.
