I've implemented a DesignSurface that uses blank UserControl and a basic DocumentDesigner. The code is based on this blog: http://bloggingabout.net/blogs/perikles/archive/2006/11/25/Using-the-Windows-Forms-designer-as-your-custom-Design-editor.-_2800_Part-I_2900_.aspx

When I do run this designer, snaplines do not appear. What can I do make the snaplines work?

I'm using VS2008. This will end up in a VSPackage that will run under the VS Shell.
Thanks!

Hi FBNitro,

You can try to override the SnapLines property of your custom designer. This property returns a list of SnapLine objects representing significant alignment points for this control. It should work if override this property. Here is a sample for your reference.

I ended up reworking the code to use the CoreDesigner and everything is working as expected now. Thanks for the reply.
