IXRUIElementCollection::Add (Compact 2013)
3/28/2014
This method adds an item to the end of the IXRUIElementCollection collection and retrieves the index that indicates where it was added.
Syntax
virtual HRESULT STDMETHODCALLTYPE Add(
__in IXRUIElement* pObject,
__out_opt int* pIndex
) = 0;
Parameters
- pObject
[in] Pointer to an IXRUIElement object that represents an item to add to this collection.
- pIndex
[out] Optional. Pointer to an integer value that indicates the zero-based index that describes the location of the item added to this collection.
Return Value
Returns S_OK if successful; otherwise, returns an HRESULT error code. If you attempt to add an item that already exists, the Add method will return XR_E_COLLECTION_ELEMENT_ALREADY_ASSOCIATED. For common error codes for XAML for Windows Embedded see XAML for Windows Embedded Error Messages.
Remarks
Because an object cannot exist more than once in a visual tree, an item can occur only once in this object collection.
