If a control has a property named "ZoomFactor", **C1Zoom** or **C1ZoomPanel** will get the control’s zoomfactor automatically and set **C1Zoom** or **C1ZoomPanel’s** zoomfactor the same as the control’s zoomfactor.

**TouchToolKit for Windows Forms** provides built-in **ZoomPolicy items** **and ZoomPolicy templates** to support standard controls and major 3rd party controls.

ZoomPolicy templates are provided as source code of **C#** and **Visual Basic**. You can modify a copy of the template to implement your custom ZoomPolicy.

To uninstall the ZoomPolicy templates from Visual Studio, delete the following zip files manually located in the **C:\\Program Files (x86)\\Microsoft Visual Studio 11.0\\Common7\\IDE\\ItemTemplates\\CSharp\\1033** folder and then run the **deven.exe //installvstemplates**.
