The property value is an object of the type [AutoSize](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/autosize/llms-full.txt).

### Syntax

public AutoSize AutoControlSize { get; set; }

```vbnet
Public Property AutoControlSize As AutoSize
```

### Examples

textControl.AutoControlSize = new AutoSize();
if (textControl.AutoControlSize != null)
{
    Console.WriteLine("Text Control: Auto Control Size is available.");
}
```

```vbnet
