Question

I have a custom hexagon menu in wpf and want to rotate it
this is the rotation code

 hexagonMenu1.RenderTransform = new RotateTransform(i,hexagonMenu1.Hexagon.ContainerRect.Width / 2, hexagonMenu1.Hexagon.ContainerRect.Height / 2);

when I call this code more than one it do nothing and panel not rotated , what can i do?
Thanks.

You would have to increase the rotation angle, i.e. your parameter i, with each new RenderTransform.

It would also be possible to reuse the existing RenderTransform and increase its Angle property:

hexagonMenu1.RenderTransform = new RotateTransform(0, hexagonMenu1.Hexagon.ContainerRect.Width / 2, hexagonMenu1.Hexagon.ContainerRect.Height / 2);
...
double deltaRotation = ...
// do the following for every rotation cycle
((RotateTransform)hexagonMenu1.RenderTransform).Angle += deltaRotation;

You might also consider to animate the rotation angle, thus eliminating the need for looping over an increasing rotation angle:

DoubleAnimation animation =
    new DoubleAnimation(360, TimeSpan.FromSeconds(10));

((RotateTransform)hexagonMenu1.RenderTransform).BeginAnimation(
    RotateTransform.AngleProperty, animation);
