Hi everybody,

I have a WPF window with Background="{x:Null}", AllowsTransparency="True" and WindowStyle="None" properties and there is an object within it, I want moving this irregular window by cursor mouse in desktop space with below code, but not work correctly, is there any idea?

C#

bool inDrag;
Point dragPoint;

private void Body3D_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    dragPoint = e.GetPosition(this);
    inDrag = true;
}

private void Body3D_MouseMove(object sender, MouseEventArgs e)
{
    if (inDrag)
    {
        Point pointMoveTo;

        // Find the current mouse position in screen coordinates.
        pointMoveTo = this.PointToScreen(e.GetPosition(this));

        // Compensate for the position the control was clicked.
        pointMoveTo.Offset(-dragPoint.X, -dragPoint.Y);

        // Compensate for the non-client region (title bar).
        // This code is not necessary if you explicitly hide the title bar
        //  by setting the form's BorderStyle to None.
        //pointMoveTo.Offset(0, -25);

        // Move the window.
        this.Top = pointMoveTo.X;
        this.Left = pointMoveTo.Y;
    }
}

private void Body3D_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
    inDrag = false;
}

Any help pls...

Thanks in advance.

Did you test above code?!
While Moving it, the window do skipping to around!
Please test it and help me:)

I don't see a reason to test it. Make it the way I demonstrated in my answer and then let's discuss if you still have any problems.

I understand your answer -=I don't see if you use isMouseDown for anything? Do you really need this status for something else, because for dragging it's not needed? I hope you do.=-

But I update the http://www.codeproject.com/Questions/277094/Why-DragMove-hold-up-some-of-other-event

and explain it for you...

You not gonna believe that, but this is all you need :-):

C#

public partial class MyWindow : Window {

    //...

    protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) {
        base.OnMouseLeftButtonDown(e);
        this.DragMove(); //begin dragging mode
    } //...

} //class MyWindow

That is, it's already done for you. See http://msdn.microsoft.com/en-us/library/system.windows.window.dragmove.aspx[^].
