Delete control in wpf canvas using LINQ

LINQ is not used from deletion of UI objects. Please see:
http://en.wikipedia.org/wiki/Language_Integrated_Query[^],
http://msdn.microsoft.com/en-us/library/vstudio/bb397926.aspx[^].

"Delete by Name" does not look accurate. You can search an object by Name (which is probably a pretty bad idea in this case) and remove the found object from the instance of the Canvas. This is a chain of MSDN help pages showing how to do it:
http://msdn.microsoft.com/en-us/library/system.windows.controls.canvas.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.controls.panel.children.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.controls.uielementcollection.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.controls.uielementcollection.remove.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.controls.uielementcollection.removeat.aspx[^].

(Was that clear? OK, this is something like myCanvas.Children.Delete(myUIElement); or myCanvas.Children.DeleteAt(myUIElementIndex). As simple as that.)
