# BaseViewer.ClientSideOptions Property 

**Applies to:** Graphics Mill Web Controls · **Archived documentation**
 
Gets/sets values which configure automatic postback for individual events.
 
**Namespace:** [Aurigma.GraphicsMill.AjaxControls](https://www.graphicsmill.com/docs/gmwc/N_Aurigma_GraphicsMill_AjaxControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.AjaxControls (in Aurigma.GraphicsMill.AjaxControls.dll)
 
## Syntax
  
```csharp
public ViewerClientSideOptions ClientSideOptions { get; }
```
 
### Property Value
 [ViewerClientSideOptions](https://www.graphicsmill.com/docs/gmwc/T_Aurigma_GraphicsMill_AjaxControls_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()() property. However if you want to disable automatic postback for certain events (e.g. Zoomed()()) and enable it for the other ones (e.g. [WorkspaceClick](https://www.graphicsmill.com/docs/gmwc/E_Aurigma_GraphicsMill_AjaxControls_BaseViewer_WorkspaceClick.htm.md)), you can use this property. It exposes a boolean property for each event.
 
This property makes sense only if AutoPostBack()() is **false**. If it is **true**, postback occurs regardless of the values of the properties of the [ViewerClientSideOptions](https://www.graphicsmill.com/docs/gmwc/T_Aurigma_GraphicsMill_AjaxControls_ViewerClientSideOptions.htm.md) object.
