Is is possible to change control's size by easily drag like VS,...

GridSplitter in Windows Community Toolkit doesn't seem to work with winui3, and it doesn't look pretty.

A method can be to use a Thumb control, like in the WPF GridSplitter :
(VerticalAlignment="Stretch" inside a Grid in this test)

Thanks! I'll go into it.

The community Toolkit is working for me with WinUI3 (I'm using CommunityToolkit.WinUI.UI.Controls 7.1.2). The two issues I haven't debugged yet are:

• The cursor doesn't change when over, only when dragging (even with ChangeOnSplitterHover set)
• I don't want the background color. You can set the Background to Transparent, but that gets overriden on mouse-over

@MikeHillberg Yes, the first point happened to be too.
If the grid layout is simple like 1 * 3, 3 * 1, the community Toolkit GridSplitter works. However, when it gets complicated, like 1 col in first row, 3 cols in second row, 2 cols in third row, the control seems incorrect.
