error: 'object' no definition/extension method

Using code (shown below) I have got an error that say this:

'object' does not contain a definition for 'RenderTransform' and no extension method 'RenderTransform' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly language

I have no idea why this is showing as an error as according to most examples (of this) this should work. Code:

public void Rotate(object sender, int rotationAmount, int centerX, int centerY)
    {
         RotateTransform rotate = new RotateTransform(rotationAmount);
         rotateTransform.CenterX = centerX;
         rotateTransform.CenterY = centerY;
         sender.RenderTransform = rotateTransform;
    }

You have to cast sender (which is declared as object) to appropriate type:

UIElement element = sender as UIElement;

if (element != null)
  element.RenderTransform = rotateTransform;

Your sender has type object, which definitely has no RenderTransform method.

You should cast it to the type you needed.

You need to cast sender to a type that has RenderTransform property.
