Need to make a custom application in which i can drag and drop (predefined) items on to a workspace and move them freely, example is of in Microsoft Office PowerPoint where a workflow diagram can be made easily ...
need a start, where can i get one ?
You may want to take a look at this CodeProject article, concerning how to create a diagram designer in WPF: http://www.codeproject.com/KB/WPF/WPFDiagramDesigner_Part1.aspx
Sounds like a fun, but big project.
I'd start here: Creating Your Own Drawing Application with Visual Basic .NET, Part 1. It's VB.NET, but it's a good start, and it';s all about the framework. Hopefully, you can translate VB.NET to C#.
Hello, I think that you need to learn how to make a simple drag and drop first. Try this tutorial or this tutorial. Hope this helps!
