RE: Create custom rectangle UI Element

Tech-Archive recommends: Speed Up your PC by fixing your registry

Hi,

I'm not sure if you're referring to System.Windows.Shaps.Rectangle:

#Rectangle Class (System.Windows.Shapes)
http://msdn2.microsoft.com/en-us/library/system.windows.shapes.rectangle.asp
x

This class cannot be inherited. It's actually only a special Shape:

#Shape Class (System.Windows.Shapes)
http://msdn2.microsoft.com/en-us/library/system.windows.shapes.shape.aspx
Provides a base class for shape elements, such as Ellipse, Polygon, and
Rectangle. This class is abstract.

The ultimate base class of them is the UIElement class:

#UIElement Class (System.Windows)
http://msdn2.microsoft.com/en-us/library/system.windows.uielement.aspx
UIElement is a base class for WPF core level implementations building on
Windows Presentation Foundation (WPF) elements and basic presentation
characteristics.


To create a visio like application, you need to manage many objects of type
UIElement, not a specific type Rectangle.

I suggest you start with following example:

#Dragging Elements in a Canvas - The Code Project - Windows Presentation
Foundation
http://www.codeproject.com/WPF/DraggingElementsInCanvas.asp

Then choose relevant samples from:

#Download details: Windows SDK .NET Framework 3.0 Samples

880d-c3339c5da01e&displaylang=en


Hope this helps.
