A preview image is available for touch zoom. Users can select a preview mode before they use the zoomfactor to operate the Form by touch.

If you would like to disable the preview set the **C1Zoom.ZoomPreviewMode** property to **NoPreview**. Also, you can use a message instead of the preview when the **C1Zoom.ZoomPreviewMode** property is set to **AlternativeContent**.

To programatically set the [C1Zoom.ZoomPreviewMode](/componentone/docs/win/online-touchtoolkit/) property to **AlternativeContent**, use the following code:

```csharp
using C1.Win.TouchToolKit;
c1Zoom1.ZoomPreviewMode = ZoomPreviewMode.AlternativeContent;
```

```vbnet
Imports C1.Win.TouchToolKit
C1Zoom1.ZoomPreviewMode = ZoomPreviewMode.AlternativeContent
```
