Gets or sets whether the DXExpander's content is expanded and collapsed with a stretching animation effect. This is a dependency property.
true if the DXExpander's content is stretched; otherwise, false. The default state is false.
If the StretchChild property is set to false, the DXExpander's content is expanded and collapsed with a sliding animation effect.
To enable stretching the DXExpander's content, the maximum control's width (for the horizontal animation) and height (for the vertical animation) must be specified. This can be done via the MaxWidth and MaxHeight properties, respectively. The content's width and height (for the horizontal and vertical animation, respectively) must not be specified.
