### Description

Gets the widths, in twips, of the columns on a page. This property is read only, to set new widths one of the SectionFormat constructors must be used.

### Syntax

```csharp
public int[] ColumnWidths { get; }
```

```vbnet
Public ReadOnly Property ColumnWidths As Integer()
```

### Examples

The following example configures the layout of the first document section by using `SectionFormat.ColumnWidths`.

```csharp
SectionFormat sectionFormat = textControl.Sections[1].Format;

foreach (int int32 in sectionFormat.ColumnWidths)
{
    Console.WriteLine(int32);
}
```

```vbnet
Dim sectionFormat As SectionFormat = textControl.Sections(1).Format

For Each int32 As Integer In sectionFormat.ColumnWidths
    Console.WriteLine(int32)
Next
```

### Limitations

Read only.

### Remarks

The size of the array is the number of columns.

The property returns null when the text selection contains multiple sections with mixed setting. The [Selection.IsCommonValueSelected](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/selection/iscommonvalueselected-method/llms-full.txt) method can be used to check for mixed attributes.
