RadCartesianChart3D cannot set initial camera position

[Paul]

if (mainChart.Camera is ProjectionCamera)
{
    ProjectionCamera projectionCamera = (ProjectionCamera)mainChart.Camera;

    Point3D point3D = projectionCamera.Position;
    point3D.X = 714;
    point3D.Y = -1852;
    point3D.Z = 1255;
    projectionCamera.Position = point3D;

    Vector3D vector3D = projectionCamera.LookDirection;
    vector3D.X = -114;
    vector3D.Y = 1952;
    vector3D.Z = -665;
    projectionCamera.LookDirection = vector3D;

}

I have the above code to try to set the initial camera position via the Loaded event but it does not work.
If I use the code on a keydown event it moves the camera to the position that I want.

What am I missing to make it set the initial camera position?

Hello Paul,

This will work if you don't have Chart3DCameraBehavior. Otherwise, you should update the camera a bit after the Loaded event is invoked. You can do that using the Dispatcher.BeginInvoke method.

private void RadCartesianChart3D_Loaded(object sender, RoutedEventArgs e)
{
    Dispatcher.BeginInvoke(new Action(() =>
    {
        ProjectionCamera projectionCamera = (ProjectionCamera)mainChart.Camera;

        Point3D point3D = projectionCamera.Position;
        point3D.X = 714;
        point3D.Y = -1852;
        point3D.Z = 1255;
        projectionCamera.Position = point3D;

        Vector3D vector3D = projectionCamera.LookDirection;
        vector3D.X = -114;
        vector3D.Y = 1952;
        vector3D.Z = -665;
        projectionCamera.LookDirection = vector3D;
    }));
}

However, if you use the Chart3DCameraBehavior, then you can consider using its properties (FirstAngle, SecondAngle, Distance and FieldOfView) instead of the Camera's properties.

Thank you, using the Chart3DCameraBehavior works best for me.
