BarCodeControl.Validate Method

Indicates whether or not the bar code is correctly rendered.

Namespace:DevExpress.XtraEditors
Assembly:DevExpress.XtraEditors.v17.2.dll

Expanded Syntax

Return value

Type: BarCodeError
A DevExpress.XtraPrinting.BarCode.BarCodeError enumeration value, identifying the error (DevExpress.XtraPrinting.BarCode.BarCodeError.None if the bar code validation succeeds).

Expanded Remarks

Call the Validate method after specifying bar code settings (e.g., in the System.Windows.Forms.Control.Paint event handler) to make sure that the resulting bar code will be properly rendered.

When validation fails (indicating that the bar code is not rendered), the control displays an error message corresponding to one of the DevExpress.XtraPrinting.Localization.PreviewStringId enumeration values.

To learn about possible errors and the corresponding text displayed in a control, see the DevExpress.XtraPrinting.BarCode.BarCodeError enumeration.
