# BaseViewer.clientSideOptions Property 
 
Gets values which configure automatic postback for individual events.
 
**Namespace:** [GraphicsMill](https://www.graphicsmill.com/docs/gm5/N_J_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill.AjaxControls (in Aurigma.GraphicsMill.AjaxControls.dll)
 
## Syntax
  
```
function get_clientSideOptions();
```
 
### Property Value
 [ViewerClientSideOptions](https://www.graphicsmill.com/docs/gm5/T_J_GraphicsMill_ViewerClientSideOptions.htm.md) class instance which provides an access to properties which configure automatic postback for individual events.
 
## Remarks
  
Automatic postback can be enabled for all events with the [autoPostBack](https://www.graphicsmill.com/docs/gm5/P_J_GraphicsMill_BaseViewer_autoPostBack.htm.md) property. However if you want to disable automatic postback for certain events (e.g. [zoomed](https://www.graphicsmill.com/docs/gm5/E_J_GraphicsMill_BaseViewer_zoomed.htm.md)) and enable it for the other ones (e.g. [workspaceClick](https://www.graphicsmill.com/docs/gm5/E_J_GraphicsMill_BaseViewer_workspaceClick.htm.md)), you can use this property. It exposes a boolean property for each event.
 
This property makes sense only if [autoPostBack](https://www.graphicsmill.com/docs/gm5/P_J_GraphicsMill_BaseViewer_autoPostBack.htm.md) is **false**. If it is **true**, postback occurs regardless of values of properties of the [ViewerClientSideOptions](https://www.graphicsmill.com/docs/gm5/T_J_GraphicsMill_ViewerClientSideOptions.htm.md) object.
 
This property corresponds to [BaseViewer.ClientSideOptions](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_AjaxControls_BaseViewer_ClientSideOptions.htm.md) server-side member.
