Let's take a look at how C# can cascade child forms.
Tools/Materials
VS 2019
Methods/Steps
1
We have a click-write event control ready in the form, which can be any control.
2
Then we write the LayoutMdi method, which does not need to return a value, so it can stand on its own.
3
At this point we call the MdiLayout class, paying attention to the spelling, because it is very similar to the spelling in step 2.
4
Then call the Cascade tiling attribute in MdiLayout's class.
5
At this time to run some of our sub-forms, can also be opened more.
6
Then click Tile and you'll see the effect.
