IRawElementProviderSimple.HostRawElementProvider Property

Gets a base provider for this element.

Namespace:  System.Windows.Automation.Provider
Assembly:  UIAutomationProvider (in UIAutomationProvider.dll)

IRawElementProviderSimple HostRawElementProvider { get; }

Property Value

Type: System.Windows.Automation.Provider.IRawElementProviderSimple
The base provider, or null.

This property is the UI Automation provider for the window of a custom control. UI Automation uses this provider in combination with your provider implementation for a control hosted in a window. For example, the run-time identifier of the element is obtained from the host provider.

A host provider must be returned in any of the following cases:

  • This element is the root of a fragment.

  • The element is a simple element such as a pushbutton.

  • The provider is a repositioning placeholder.

In other cases, the property should return null.

The following example code shows an implementation of HostRawElementProvider for a fragment root that is hosted in a Windows form.

IRawElementProviderSimple IRawElementProviderSimple.HostRawElementProvider  
        // myHWND is the handle of the window that contains this control. 
        return AutomationInteropProvider.HostProviderFromHandle(myHWND);
