### Description

Gets or sets the font family at the current input position. If text is selected, the property specifies the font family of the whole selected text.

### Syntax

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

```vbnet
Public Property FontFamily As String
```

### Examples

The following XAML example shows how to bind a combo box to the FontFamily property using [GetFontFamilies](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol/inputformat/getfontfamilies-method/llms-full.txt) to fill the combo box with available font names.

```plaintext
<ComboBox
    Name="cbFontFamily"
    IsEditable="True"
    IsReadOnly="True"
    Width="150"
    DropDownOpened="cbFontFamily_DropDownOpened"
    Text="{Binding ElementName=textControl1, Path=InputFormat.FontFamily}" />
```

```csharp
private void cbFontFamily_DropDownOpened(object sender, EventArgs e) {
    cbFontFamily.ItemsSource = textControl1.InputFormat.GetFontFamilies();
}
```

```vbnet
Private Sub cbFontFamily_DropDownOpened(sender As Object, e As EventArgs)
    cbFontFamily.ItemsSource = textControl1.InputFormat.GetFontFamilies()
End Sub
```

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

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

inputFormat.FontFamily = "Arial";
if (!string.IsNullOrWhiteSpace(inputFormat.FontFamily))
{
    Console.WriteLine($"Font Family: {inputFormat.FontFamily}");
}
```

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

inputFormat.FontFamily = "Arial"
If Not String.IsNullOrWhiteSpace(inputFormat.FontFamily) Then
    Console.WriteLine($"Font Family: {inputFormat.FontFamily}")
End If
```

### Remarks

The property returns null when the text selection contains multiple characters with mixed font names.
