Example

The following example sets a parameter’s Enabled property to false to make the default value of this parameter read-only.

C#

using DevExpress.XtraReports.Parameters;
// ...
report.Parameters["customer"].Enabled = false;

VB.NET

Imports DevExpress.XtraReports.Parameters
' ...
report.Parameters("customer").Enabled = False

The example below specifies an expression for a parameter’s Enabled property to enable/disable the parameter’s editor based on a value of another parameter.

C#

using DevExpress.XtraReports.Parameters;
// ...
using DevExpress.XtraReports.Expressions;
// ...
report.Parameters["company"].ExpressionBindings.Add(
    new BasicExpressionBinding() {
        PropertyName = "Enabled",
        Expression = "!IsNullOrEmpty(?customer)",
});

VB.NET

Imports DevExpress.XtraReports.Parameters
' ...
Imports DevExpress.XtraReports.Expressions
' ...
report.Parameters("company").ExpressionBindings.Add(
    New BasicExpressionBinding() With {
        .PropertyName = "Enabled",
        .Expression = "!IsNullOrEmpty(?customer)"
})
