Thank you for the question.
When you float a ToolWindow, you should subscribe to the LocationChanged property of the ToolWindow's FloatingParent. Let's assume that we have a docked ToolWindow that the user floats at runtime. The code that will allow you to track the location changes of the floating form is:
Form1 : Form
sender, Telerik.WinControls.UI.Docking.DockWindowEventArgs e)
(e.DockWindow.DockState == Telerik.WinControls.UI.Docking.DockState.Floating)
floatingW = e.DockWindow.FloatingParent;
sender, EventArgs e)
I hope this helps.
