Specifies the output format for a value bound to the barcode.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v22.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

[Browsable(true)]
public override string TextFormatString { get; set; }

VB.NET

<Browsable(True)>
Public Overrides Property TextFormatString As String

Property Value

Type	Description
String	The output format for a value bound to the barcode.

Remarks

The TextFormatString property allows you to specify an output format for values bound to the XRBarCode‘s Text property.

Note

Ensure that the specified format string fits the type of the bound value. For instance, in the code example below the expression {0:(####)-####} expects the code field to be an integer. This expression does not work for other types, for example for strings. Refer to the following article for more details on formatting: Format types in .NET.

Example

The following code example shows how to specify the TextFormatString property for the XRBarCode control.

Note

Refer to the following help topic for information on how to format data at design time: Format Data.

C#

using DevExpress.XtraReports.UI;
using DevExpress.DataAccess.Json;
// ...
string json = "{\"codes\":[{\"code\":12341234},{\"code\":56785678}]}";

// Create a barcode.
XRBarCode barcode = new XRBarCode() {
    HeightF = 150, WidthF = 550,
    TextAlignment = DevExpress.XtraPrinting.TextAlignment.MiddleCenter,
    // Specify an expression for the barcode's "Text" property.
    ExpressionBindings = { new ExpressionBinding("BeforePrint", "Text", "[code]") },
    // Specify a format string for the barcode's text.
    TextFormatString = "{0:####-#-###}"
};

// Create a report with the barcode.
XtraReport report = new XtraReport() {
    Bands = {
        new DetailBand() {
            HeightF = 200,
            Controls = {barcode}
        }
    },
    DataSource = new JsonDataSource() {
        JsonSource = new CustomJsonSource(json)
    },
    DataMember = "codes"
};

VB.NET

Imports DevExpress.XtraReports.UI
Imports DevExpress.DataAccess.Json
' ...
Dim json As String = "{""codes"":[{""code"":12341234},{""code"":56785678}]}"

' Create a barcode.
Dim barcode As New XRBarCode() With {
.HeightF = 150,
.WidthF = 550,
.TextAlignment = DevExpress.XtraPrinting.TextAlignment.MiddleCenter,
.TextFormatString = "{0:####-#-###}"}
barcode.ExpressionBindings.Add(New ExpressionBinding("BeforePrint", "Text", "[code]"))

' Create a report with the barcode.
Dim report = New XtraReport()
Dim band = New DetailBand() With {.HeightF = 25}
band.Controls.Add(barcode)
report.DataSource = New JsonDataSource() With {.JsonSource = New CustomJsonSource(json)}
report.DataMember = "codes"
