### Description

Gets or sets the formatting style name at the current input position. If text is selected, the property specifies the style of the whole selected text.

### Syntax

```csharp
public string StyleName { get; set; }
```

```vbnet
Public Property StyleName As String
```

### Examples

The following XAML example shows how to bind the StyleName property to a combo box which contains all style names returned by the [StyleNames](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/inputformat/stylenames-property/llms-full.txt) property.

```plaintext
<ComboBox
    Width="200"
    IsEditable="True"
    IsReadOnly="True"
    Text="{Binding ElementName=textControl1, Path=InputFormat.StyleName}"
    ItemsSource="{Binding ElementName=textControl1, Path=InputFormat.StyleNames}" />
```

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

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

inputFormat.StyleName = "CustomerName";
if (!string.IsNullOrWhiteSpace(inputFormat.StyleName))
{
    Console.WriteLine($"Style Name: {inputFormat.StyleName}");
}
```

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

inputFormat.StyleName = "CustomerName"
If Not String.IsNullOrWhiteSpace(inputFormat.StyleName) Then
    Console.WriteLine($"Style Name: {inputFormat.StyleName}")
End If
```

### Remarks

The property returns null when the text selection contains multiple characters with different styles.
