C#

Is there any freeware word editor having all features including flow chart and organisation chart in C# Winform or Wpf ?
If no freeware editor available then is there any third party controls having all same features of MSWord.I saw Devexpress rcihtext editor and telerik Radrichtext box .But in both third party controller it is hard to insert image from flow chart in richtextbox ?Also Devexpress doesn't have this facility?I tried for spire.doc but it is hard to insert Word editor as OLE object using spire.
