    For a project, i need to resize ToolWindows when they are floating, and are at a certain position at the screen, but the onlocationChange event isn't fired when I move the floating window on the screen

    It is fired  before i make the window floating.

    I'm using the 2010 Q2 SP1 release.

    Hi Gerben,

    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:
    public partial class Form1 : Form
        public Form1()
            this.radDock1.DockStateChanged += new Telerik.WinControls.UI.Docking.DockWindowEventHandler(radDock1_DockStateChanged);
        FloatingWindow floatingW;
        void radDock1_DockStateChanged(object sender, Telerik.WinControls.UI.Docking.DockWindowEventArgs e)
            if (e.DockWindow.DockState == Telerik.WinControls.UI.Docking.DockState.Floating)
                floatingW = e.DockWindow.FloatingParent;
                floatingW.LocationChanged += new EventHandler(floating_LocationChanged);
        void floating_LocationChanged(object sender, EventArgs e)

    I hope this helps.
    Sincerely yours,
    the Telerik team
