When moving from TMS Component Pack to TMS VCL UI Pack and you are using the TAdvTreeView you could potentially run into compilation errors and errors when opening the form. Things that have changed between the older TAdvTreeView and the new implementation are:

• TCanvas is now TAdvGraphics
• Drag & Drop support is built in
• FontColor is no longer a separate color but integrated in Font.Color
• Property types are different
• Fill and Stroke is available as styling properties
• Icons/Images can be added via TPicture instead of TGraphic
