Exception when parsing degrees. From XML: 

 transform: rotate(180deg);
 

An ObjectDisposedException exception is raised when a RadSvgImage is placed in a DataTemplate. It is present when the XmlSource property is utilized.

As a workaround, you can place the SVG string into a new .svg file and utilize the UriSource property of RadSvgImage.

When i set the Urisource through a binding and not directly through the xaml the svg image is not shown in combination with paint servers.

I had a look at the code and the issue is that the paint server gets not set again (see attachment)
