Our Demo application >> WaitingBar >> WaitingBar Settings example gives you the experience to play with the animation settings.
In case you want to load a gif file instead the waiting animation, you won't need RadWaitingBar. You can simply apply the desired gif file as an image in RadButton or PictureBox for example.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
