The property's value is a member of the [NumberFormat](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/numberformat/enumeration/llms-full.txt) enumeration.

### Syntax

```csharp
public NumberFormat StructuredListFormat { get; set; }
```

```vbnet
Public Property StructuredListFormat As NumberFormat
```

### Examples

The following XAML example shows how to bind radio buttons to the StructuredListFormat property using the [WPF.BooleanConverter](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol-wpf/booleanconverter/llms-full.txt) class and the [NumberFormats](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/inputformat/numberformats-property/llms-full.txt) property.

```plaintext
…
xmlns:tx="clr-namespace:TXTextControl.WPF;assembly=TXTextControl.WPF"
…
<Window.Resources>
    <tx:BooleanConverter x:Key="boolConv" />
</Window.Resources>
…
<RadioButton
    Content="{Binding ElementName=textControl1, Path=InputFormat.NumberFormats[0], Mode=OneTime}"
    GroupName="structuredListFormat"
    IsChecked="{Binding
        ElementName=textControl1,
        Path=InputFormat.StructuredListFormat,
        Converter={StaticResource boolConv},
        ConverterParameter=ArabicNumbers}" />
<RadioButton
    Content="{Binding ElementName=textControl1, Path=InputFormat.NumberFormats[1], Mode=OneTime}"
    GroupName="structuredListFormat"
    IsChecked="{Binding
        ElementName=textControl1,
        Path=InputFormat.StructuredListFormat,
        Converter={StaticResource boolConv},
        ConverterParameter=Letters}" />
…
```

The following example changes the formatting applied to text entered at the end of a document by using `InputFormat.StructuredListFormat`.

```csharp
textControl.Text = "Project summary";
textControl.InputPosition = new InputPosition(textControl.Text.Length);
InputFormat inputFormat = textControl.InputFormat;

inputFormat.StructuredListFormat = NumberFormat.ArabicNumbers;
Console.WriteLine($"Structured List Format used by Input Format: {inputFormat.StructuredListFormat}");
```

```vbnet
textControl.Text = "Project summary"
textControl.InputPosition = New InputPosition(textControl.Text.Length)
Dim inputFormat As InputFormat = textControl.InputFormat

inputFormat.StructuredListFormat = NumberFormat.ArabicNumbers
Console.WriteLine($"Structured List Format used by Input Format: {inputFormat.StructuredListFormat}")
```

### Remarks

The property's default value is NumberFormat.ArabicNumbers.

The property returns NumberFormat.None, if the text selection has no common number format.
