VisualTreeHelper::GetChild Method (DependencyObject^, Int32)
Returns the child visual object from the specified collection index within a specified parent.
Assembly: PresentationCore (in PresentationCore.dll)
Parameters
- reference
-
Type:
System.Windows::DependencyObject^
The parent visual, referenced as a DependencyObject.
- childIndex
-
Type:
System::Int32
The index that represents the child visual that is contained by reference.
Call the GetChildrenCount method to determine the total number of child elements of a parent visual.
The value of reference can represent either a Visual or Visual3D object, which is why the common base type DependencyObject is used here as a parameter type.
The following example shows how to enumerate all the descendants of a visual object. This is a technique you might use if you are interested in serializing all the rendering information of a visual object hierarchy or are performing analysis or alternative rendering.
