RadSlider ticks are not positioned properly in IE11 with TrackPosition="TopLeft" and lightweight rendering.

Configuring ItemType and Items properties of RadSlider through the properties window in Visual Studio is not possible (leading to errors).

Can you add a close animation to a RadSlider similar to how you can set an opening animation/duration. If so can the animation duration be set independently for open/close.

Currently the property LargeChange of RadSlider controls the following behaviors:

 - The interval for displaying value numbers in a slider with ticks;

 - The interval for moving the drag handle when an item in the slider is clicked. For example when LargeChange is set to 10, the currently selected value is 30 and the item with value 50 is clicked, the drag handle will be moved to 40;

Separating these functionalities will allow directly moving the drag handle to a clicked value on the slider track and displaying value numbers in the slider at the same time.

When scrolling the page and the finger is on the slider, the slider value changes.

The following code prevents the scrolling when you scroll from the slider.

function pageLoadHandler() {
    $telerik.$(".RadSlider").on('touchstart', function (e) {
        e.preventDefault();
    });
}
Sys.Application.add_load(pageLoadHandler);

When the ItemType property of RadSlider is set to Item, the ticks of the control are positioned between its items. This feature will allow you to change the position of the ticks so that they will appear on the actual items, not between them.

It will be possible to include more than one selection range in RadSlider.

It will be possible to create a non-linear RadSlider, the items/values of which will not be positioned evenly on the slider track. This distribution of the items/values will be determined by a custom function.

When ItemType=Item and AutoPostBack=true RadSlider performs the postback in the onmousedown event of the increase/decrease handles. This should happen only when the button is clicked with this item type, because there isn't a small change. This will allow the end user to change his/her mind like a regular button would allow you to click, hold the mouse button down, move the mouse out of the button and release without performing the postback.
