Append a MenuStrip to an MDI Parent Window (Windows Forms) c# (or) mdi child menu in wpf

In this post, I explained how to bind data to menu strip in MDI PARENT FORM. multiple-document interface (MDI) child window can be different from the MDI parent window. For example, the MDI parent might be a spreadsheet, and the MDI child might be a chart, I have used stored procedures in this article.  I have binded the menu strip based on the role of the user.
