Hi Tobias,

I apologize for the late response. We investigated and considered this scenario as really case specific and that is why the item is declined. However we plan to work on improving the performance of control and this will also include drag and drop scenarios - we will consider this particular case as well. Meanwhile we really hope the suggested workaround is suitable for your scenario and if you have any other questions or concerns - please let us know.

Regards,
Kalin

Hi,

After further investigation appeared the behavior is caused due to the heavy content of the Pane and the fast dragging in this particular scenario. The drag operation cannot be initialized on time - this leads to the issue as the Pane doesn't release the MouseCapture at the correct moment. What we can suggest as workaround to a similar behavior would be to hook to the MouseLeave event of the Docking control and release the mouse capture if RadPane has captured the mouse.

public MainWindow()
{
    InitializeComponent();
    this.Docking.AddHandler(RadDocking.MouseLeaveEvent, new MouseEventHandler(OnMouseLeave), true);
...
}


private void OnMouseLeave(object sender, MouseEventArgs e)
{
    var captured = Mouse.Captured as RadPane;
    if (captured != null)
    {
        captured.ReleaseMouseCapture();
    }
}

Regards,
Kalin
