CheckSumEnabled has no effect if the style is EAN-13 and the result is based on the length of the string as follows:

Under 12 digits	Barcode symbol is not generated. Error message appears on the control.
12 digits	Check digit is calculated automatically (modulus 10/ weight 3). The barcode symbol is generated once the 13th digit is added.
13 digits or above	Strings with 13 digits or above are ignored and check digit is calculated automatically till the 12th digit. The barcode symbol is generated once the 13th digit is added.

Example

private void detail_Format(object sender, System.EventArgs eArgs)
{
    this.barcode1.CheckSumEnabled = true;
}

Visual Basic

Private Sub Detail1_Format(ByVal sender As Object, ByVal e As System.EventArgs) Handles Detail1.Format
    Me.Barcode1.CheckSumEnabled = True
End Sub
