# UserInputController Class
 
This client-side class corresponds to the [UserInputController](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_AjaxControls_UserInputController.htm.md) server-side class and gives an opportunity to obtain access to its primary members in JavaScript.
 
**Namespace:** [GraphicsMill](https://www.graphicsmill.com/docs/gm5/N_J_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill.AjaxControls (in Aurigma.GraphicsMill.AjaxControls.dll)
 
## Syntax
  
```
GraphicsMill.UserInputController = function();

Type.createClass('GraphicsMill.UserInputController',Sys.UI.Control);
```
 
## Remarks
  
All the client-side classes intended to manage user input (such as mouse events) of the [BaseViewer](https://www.graphicsmill.com/docs/gm5/T_J_GraphicsMill_BaseViewer.htm.md) control are inherited from this class.
 
[UserInputController](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_AjaxControls_UserInputController.htm.md) class is an abstract one, you cannot instantiate it directly.
