Property Value

Type Description

A parameter description.

Example

To create a parameter in code, initialize a Parameter class instance and specify its properties. Add the parameter to the report’s Parameters collection.

The code sample below demonstrates how to create a date parameter, specify an expression for the parameter’s default value, and reference the parameter in a label‘s expression.

Date parameter example

using System.Drawing;
using DevExpress.XtraReports.UI;
// ...
using DevExpress.XtraReports.Parameters;
// ...
using DevExpress.XtraReports.Expressions;
// ...
// Create a date report parameter.
// Use an expression to specify the parameter's default value.
var dateParameter = new Parameter() {
    Name = "date",
    Description = "Date:",
    Type = typeof(System.DateTime),
    ExpressionBindings = { new BasicExpressionBinding("Value", "Now()") }
};

// Create a label and bind the label's Text property to the parameter value.
// Use the parameter's name to reference the parameter in the label's expression.
var dateLabel = new XRLabel() {
    ExpressionBindings = { new ExpressionBinding("Text", "?date") },
    BoundsF = new RectangleF(0, 0, 200, 50),
};

// Create a report and add the label to the report's Detail band.
var report = new XtraReport() {
    Bands = { new DetailBand() { Controls = { dateLabel } } },
};

// Add the parameter to the report's Parameters collection.
report.Parameters.Add(dateParameter);
