# IOptionsManager interface

The `IOptionsManager` interface deals with the options of a system wide Preferences dialog or project centric Project Options dialog.

```csharp
public interface IOptionsManager
```

**Namespace:** DXP · **Assembly:** Altium.SDK.Interfaces

## Remarks

A server needs to register its own options pages within the Client module of Altium Designer. The TServerModule class from the RT_ServerImplementation unit within the Altium Designer RTL has a RegisterOptionsPageClass method for you to override. You need to pass in the name of the options page and the Options Form of TOptionsForm type. Normally this form is the same as the server panel form with the controls on it.
