### Description

Gets or sets a value specifying whether there is a frame line at the top of the text. If text is selected, the property specifies this attribute for the whole selected text.

### Syntax

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

```vbnet
Public Property TopFrameLine As Boolean
```

### Examples

The following XAML example shows how to bind the TopFrameLine property to a checkable menu item.

```plaintext
<MenuItem
    IsCheckable="True"
    Header="Top Frame Line"
    IsChecked="{Binding ElementName=textControl1, Path=InputFormat.TopFrameLine}" />
```

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

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

inputFormat.TopFrameLine = true;
if (inputFormat.TopFrameLine)
{
    Console.WriteLine("Input Format: Top Frame Line is enabled.");
}
```

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

inputFormat.TopFrameLine = True
If inputFormat.TopFrameLine Then
    Console.WriteLine("Input Format: Top Frame Line is enabled.")
End If
```
