1) View the same document side by side (with fix for Visual Studio 2017)
This can be done using the New Window and New Vertical Tab Group , however, in my Visual Studio 2017, the New Window command was missing from the Window menu. To use it, you must first add a command to the menu or assign a shortcut to it.
To add a New Window to your Window menu, follow this sequence, starting with the Tools menu:
Tools > Customize > Commands > Menu Bar > Window > Add Command > Window > New Window
FYI In the Commands step, you decide where to put the New Window command. The sequence I gave above makes it unceremoniously at the top of the Window menu.
To view the same document side by side
- Open the document you want to view side by side
- Select the recently added
New Window command (perhaps it is in Window > New Window ) - Right-click on the new tab and select
New Vertical Tab Group or select this command from the Window menu.
2) View the same document above one another
If you want to view the same document in two views, one above the other, use the Window > Split command or click and drag the double arrow at the top of the scroll bar for any window.
3) Create an ad
Fyi. You can even combine two view options with three, four or even more views of the same document on a particularly wide monitor. On my (2560 x 1080) I can comfortably get three side views, walking and , if desired, break them down vertically.
