protected:
 virtual property int VisualChildrenCount { int get(); };

protected virtual int VisualChildrenCount { get; }

member this.VisualChildrenCount : int

Protected Overridable ReadOnly Property VisualChildrenCount As Integer

Property Value

Int32

The number of child elements.

Examples

The following example defines an overridden implementation of VisualChildrenCount.

// Provide a required override for the VisualChildrenCount property.
protected override int VisualChildrenCount
{
    get { return _children.Count; }
}

' Provide a required override for the VisualChildrenCount property.
Protected Overrides ReadOnly Property VisualChildrenCount() As Integer
    Get
        Return _children.Count
    End Get
End Property

Remarks

By default, a Visual has no children. Therefore, the default implementation always returns 0.

Notes to Inheritors

A class that derives from Visual must override this property, and also the GetVisualChild(Int32) method, for the visual tree to be enumerated correctly.
