# ViewerClientSideOptions Class
 
Exposes properties which configure automatic postback for individual events of the [BaseViewer](https://www.graphicsmill.com/docs/gm5/T_J_GraphicsMill_BaseViewer.htm.md) control.
 
**Namespace:** [GraphicsMill](https://www.graphicsmill.com/docs/gm5/N_J_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill.AjaxControls (in Aurigma.GraphicsMill.AjaxControls.dll)
 
## Syntax
  
```
GraphicsMill.ViewerClientSideOptions = function();

Type.createClass('GraphicsMill.ViewerClientSideOptions');
```
 
## Remarks
  
Instances of the ViewerClientSideOptions class are returned by the [BaseViewer.clientSideOptions](https://www.graphicsmill.com/docs/gm5/P_J_GraphicsMill_BaseViewer_clientSideOptions.htm.md) property.
 
Each property of this class enables or disables automatic postback for appropriate event. However if the [BaseViewer.autoPostBack](https://www.graphicsmill.com/docs/gm5/P_J_GraphicsMill_BaseViewer_autoPostBack.htm.md) value is **true**, automatic postback occurs regardless of these properties values.
