Hi,

I am getting an unhandled exception when I try to resize XamNetworkNode with a GridSplitter. Attached the sample project and snapshots.

System.Reflection.TargetInvocationException occurred   _HResult=-2146232828   _message=Exception has been thrown by the target of an invocation.   HResult=-2146232828   IsTransient=false   Message=Exception has been thrown by the target of an invocation.   Source=mscorlib   StackTrace:        at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)        at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)   InnerException: System.ArgumentOutOfRangeException        _HResult=-2146233086        _message=The parameter value must be greater than zero.        HResult=-2146233086        IsTransient=false        Message=The parameter value must be greater than zero. Parameter name: pixelHeight        Source=PresentationCore        ParamName=pixelHeight        StackTrace:             at System.Windows.Media.Imaging.RenderTargetBitmap..ctor(Int32 pixelWidth, Int32 pixelHeight, Double dpiX, Double dpiY, PixelFormat pixelFormat)             at Infragistics.Controls.Maps.NetworkNodeNodesPanel.Render()             at Infragistics.Controls.Maps.XamNetworkNode.ArrangeElements(Boolean immediate, Boolean refreshThumbnail)

I have a Grid with 3 RowDefinitions, with XamNetworkNode in 1st row, Splitter in 2nd Row & Some other control in 3rd Row. When I drag the splitter upwards trying to increase the height of row 3, I am getting an unhandled exception. It is coming when the XamNetworkNode's  visible height is almost approaching zero.

Can any one please help on fixing this exception.

Thanks
