What you have two separate RadDocking controls it should be possible to drag a Pane from the first control into the other one.

In a multi monitor scenario with different scalings and an application that is configured to run ‚per monitor dpi awareness‘ a floating toolwindow cannot be docked at all positions.

Example:

Monitor 1: 1920 x 1200 (100%), Monitor 2: 2048 x 2560 (150%)

Our WPF application has a main window, maximized on screen 1 and a child window maximized on screen 2.

In the app.manifest we use per monitor dpi awareness.

Both windows have a RadDocking instance with a docked RadPane. Start the application, undock a tool window and try to dock it at the right position on monitor 1.

è It is not possible since the compass is deactivated before the mouse cursor reaches the right monitor area.

Like RanTabControl

Need this for an application with lots of tabs wich would not fit in the top or bottom template.

Maybe it works with a customizable TabStripTemplate where i can implement e.g. a GridView or something

Like this with a scrollbar (used TabControl PRISM example for this)
