### Description

### Syntax

```csharp
public int TopLineWidth { get; set; }
```

```vbnet
Public Property TopLineWidth As Integer
```

### Examples

The following example configures the page border of the first document section by using `PageBorder.TopLineWidth`.

```csharp
PageBorder pageBorder = textControl.Sections[1].Format.PageBorder;

pageBorder.TopLineWidth = 100;
Console.WriteLine($"Top Line Width used by Page Border: {pageBorder.TopLineWidth}");
```

```vbnet
Dim pageBorder As PageBorder = textControl.Sections(1).Format.PageBorder

pageBorder.TopLineWidth = 100
Console.WriteLine($"Top Line Width used by Page Border: {pageBorder.TopLineWidth}")
```

### Remarks
