This method retrieves the item at the specified index in the IXRUIElementCollection collection.

Syntax

virtual HRESULT STDMETHODCALLTYPE GetItem(
  __in int ItemIndex,
    __out IXRUIElement** ppObject
) = 0;

Parameters

ItemIndex
[in] Integer value that specifies the index of the location of the item to retrieve.

ppObject
[out] Pointer to a pointer to an IXRUIElement object that represents the item located in the collection at the index specified in ItemIndex.

Return Value

Returns S_OK if successful; otherwise, returns an HRESULT error code. For common error codes for XAML for Windows Embedded, see XAML for Windows Embedded Error Messages.

Remarks

To use a specific interface pointer type, use the helper template version of this method that XAML for Windows Embedded provides. When you supply a derived type, this version automatically supplies a type-safe method that implicitly converts the returned type from a generic interface, so you do not have to explicitly call QueryInterface to convert the generic interface into the required object type.

.NET Framework Equivalent

None.

Requirements

Header	XamlRuntime.h
sysgen	SYSGEN_XAML_RUNTIME
