IXRApplication::ParseXamlWithExistingRoot (Compact 2013)

3/28/2014

This method parses the source XAML and adds it to an existing root in the visual tree.

Syntax

virtual HRESULT STDMETHODCALLTYPE ParseXamlWithExistingRoot(
    XRXamlSource* pSource,
    IXRDependencyObject* pExistingRoot
) = 0;

pSource
[in] Pointer to an XRXamlSource structure that describes the source XAML that must be parsed into a new element tree.

pExistingRoot
[in] Pointer to an IXRDependencyObject object that is the root element of an existing visual tree onto which the new element tree must be appended.

Returns an HRESULT that indicates success or failure.

When a XAML parser error occurs, this method can also return one of the following error messages:
