How to Set Word Document View and Prevent Save Prompts in C#

In your C# code, target the ActiveWindow.View property of your Word Document object (e.g., oDoc.ActiveWindow.View).

Assign the WdViewType.wdPrintView enumeration to the Type property to ensure the document displays in Print Layout. Example code: oDoc.ActiveWindow.View.Type = WdViewType.wdPrintView;

To control the page scaling, utilize the Zoom property. Set oDoc.ActiveWindow.View.Zoom.PageFit = WdPageFit.wdPageFitFullPage to display a single page vertically.

Check your Word document for auto-executing macros or fields that update automatically upon opening, as these mark the document as 'dirty'.

Before invoking the Close method in your C# code, explicitly tell Word that the document is already saved by setting oDoc.Saved = true;

Pass the do not save parameter when closing the document. Example: oDoc.Close(WdSaveOptions.wdDoNotSaveChanges);

Change your application logic to show the navigation form using the .Show() method instead of .ShowDialog().

Temporarily minimize your main C# form right before initializing and displaying the Word document to prevent overlap.

Attach an event listener to restore your main form's window state to Normal once the navigation form or Word document is closed.
