### Description

Gets or sets the structure level of a paragraph in the document. The level can be between 0 and 10. A level of 0 indicates that the paragraph belongs to the body of the document.

### Syntax

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

```vbnet
Public Property StructureLevel As Integer
```

### Examples

The following example applies paragraph layout to selected report text by using `ParagraphFormat.StructureLevel`.

```csharp
textControl.Text = "First item\nSecond item\nThird item";
textControl.Select(0, textControl.Text.Length);
ParagraphFormat paragraphFormat = textControl.Selection.ParagraphFormat;

paragraphFormat.StructureLevel = 10;
Console.WriteLine($"Structure Level used by Paragraph Format: {paragraphFormat.StructureLevel}");

textControl.Selection.ParagraphFormat = paragraphFormat;
```

```vbnet
textControl.Text = "First item" & vbCrLf & "Second item" & vbCrLf & "Third item"
textControl.Select(0, textControl.Text.Length)
Dim paragraphFormat As ParagraphFormat = textControl.Selection.ParagraphFormat

paragraphFormat.StructureLevel = 10
Console.WriteLine($"Structure Level used by Paragraph Format: {paragraphFormat.StructureLevel}")

textControl.Selection.ParagraphFormat = paragraphFormat
```

### Remarks

The property's default value is 0.

The property returns its default value when the text selection contains multiple paragraphs with mixed structure levels. The [Selection.IsCommonValueSelected](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol/selection/iscommonvalueselected-method/llms-full.txt) method can be used to check for mixed attributes.
