### Description

Gets or sets a value indicating whether the check value of the [current used barcode type](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-barcode/txbarcodecontrol/barcodetype-property/llms-full.txt) is [shown](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-barcode/txbarcodecontrol/showtext-property/llms-full.txt) with the encrypted [barcode text](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-barcode/txbarcodecontrol/text-property/llms-full.txt) value.

### Syntax

```csharp
public bool ShowCheckValue { get; set; }
```

```vbnet
Public Property ShowCheckValue As Boolean
```

### Examples

The following example uses `BarcodeTypeSettings.ShowCheckValue` to configure show check value as part of the barcode type settings workflow. The configured value is checked before the workflow continues.

```csharp
barcodeTypeSettings.ShowCheckValue = true;
if (barcodeTypeSettings.ShowCheckValue)
{
    Console.WriteLine("Barcode Type Settings: Show Check Value is enabled.");
}
```

```vbnet
barcodeTypeSettings.ShowCheckValue = True
If barcodeTypeSettings.ShowCheckValue Then
    Console.WriteLine("Barcode Type Settings: Show Check Value is enabled.")
End If
```

### Limitations

By default the following supported barcode types display the check sum with the encrypted [barcode text](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-barcode/txbarcodecontrol/text-property/llms-full.txt) value if the [BarcodeTypeSettings.HasCheckValue](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-barcode/barcodetypesettings/hascheckvalue-property/llms-full.txt) property returns true: `Interleaved2of5`, `Code39`, `EAN13`, `EAN8`, `UPCA`, `Postnet` and `Codabar`.

For the following barcode types this property can be used to determine whether the check sum is displayed with the encrypted [barcode text](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-barcode/txbarcodecontrol/text-property/llms-full.txt) value if the [BarcodeTypeSettings.HasCheckValue](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-barcode/barcodetypesettings/hascheckvalue-property/llms-full.txt) property returns true: `Code128`, `Interleaved2of5`, `Code39`, `Postnet`, `Codabar`, `Code11`, `Code93`, `PLANET` and `RoyalMail`.
