         OnMouseLeave.KeyFrames.Add(new SplineDoubleKeyFrame(0, KeyTime.FromTimeSpan(TimeSpan.FromSeconds(.5))));

         Storyboard.SetTargetProperty(InfExtraGrid, new PropertyPath(TranslateTransform.YProperty));
         Storyboard strbStoryboard = new Storyboard();
         strbStoryboard.Children.Add(OnMouseLeave);
         strbStoryboard.Begin(this);

OK, this is just a code dump. But what's the problem?
You have to start with what you want to achieve...

Hi,

I think you are setting the TargetProperty wrong and you aren't setting the TargetName of the storyboard.

Instead of:

C#

Storyboard.SetTargetProperty(InfExtraGrid, new PropertyPath(TranslateTransform.YProperty));

write:

C#

Storyboard.SetTargetName(OnMouseLeave, "InfExtraGrid");
Storyboard.SetTargetProperty(OnMouseLeave, new PropertyPath("(Grid.RenderTransform).(TransformGroup.Children)[0].(TranslateTransform.Y)");

TargetName and TargetProperty are attached properties of the animation instance (from Storyboard), in this instance the OnMouseLeave object,
so you have to set these properties on the OnMouseLeave and not the InfExtraGrid object.

Hope this helps,

Thomas.
