Glad you chose to evaluate our controls and here are the answers to your questions:
- I am attaching a simple example demonstrating how to use the slider within an Update Panel for partial Post-Backs. First of all, you need to set the AutoPostBack property of the Slider to true to ensure that the control does PostBacks since you will be using it in the UpdatePanel to trigger the assync PostBacks.
You will see that in my example, I use two labels, within and outside the UpdatePanel to demonstrate that partial PostBack takes place as you move the slider.
- Regarding the slide animation, the answer is yes indeed! You can set the control's animation with the AnimationDuration property which defines how long (in milliseconds) the animation of the slide action will run as shown in this online demo:
