# BaseViewer.ClientSideOptions Property 
 
Gets/sets values which configure automatic postback for individual events.
 
**Namespace:** [Aurigma.GraphicsMill.AjaxControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_AjaxControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.AjaxControls (in Aurigma.GraphicsMill.AjaxControls.dll)
 
## Syntax
  
```
<BrowsableAttribute(True)> _
Public ReadOnly Property ClientSideOptions As ViewerClientSideOptions
```
 
```csharp
[BrowsableAttribute(true)]
public ViewerClientSideOptions ClientSideOptions { get; }
```
 
### Property Value
 [ViewerClientSideOptions](https://www.graphicsmill.com/docs/gm5/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](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_AjaxControls_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_Aurigma_GraphicsMill_AjaxControls_BaseViewer_Zoomed.htm.md)) and enable it for the other ones (e.g. [WorkspaceClick](https://www.graphicsmill.com/docs/gm5/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](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_AjaxControls_BaseViewer_AutoPostBack.htm.md) is **false**. If it is **true**, postback occurs regardless of the values of the properties of the [ViewerClientSideOptions](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_AjaxControls_ViewerClientSideOptions.htm.md) object.
