Sliderextender not working on touchscreen

Question

Hello everyone,

I added the slider extension to a text box and it works great on the computer by selecting it with the mouse.

If I display the page through a smartphone the pointer does not move with the finger, but the whole page moves. if I select another point on the scroll bar, then the pointer will be moved to the point I selected.

Is it possible to move the pointer with the finger in the same way as with the mouse?

I am grateful
Constantinos

Hi @Constantinos Arist ,
As far as I think,the slider extension is a ajax tool control. And the ajax control in touch device is not enough supported. If one ajax control have the click event,it will run ok in touch device.But if it have the drag or drop event,it may dose not work fine.The broswer will be confused by event. I think when you want to drag or drop the control in touch device,safar (or other broswer) get this event and broswer will excult this event,the ajax control does not get the drag or drop event.
So I suggest You could visit to the Microsoft Visual Studio UserVoice site. Let us know what you would like to see in future versions of the Visual Studio suite of products. This site is for suggestions and ideas.

I assume you are using asp.net ajax control toolkit. this is now an open source project:

https://github.com/DevExpress/AjaxControlToolkit/tree/master/AjaxControlToolkit

you could open an issue (I don't know how responsive they are).

https://github.com/DevExpress/AjaxControlToolkit/issues

or you could fix the code and do a pull request.

https://github.com/DevExpress/AjaxControlToolkit/blob/master/AjaxControlToolkit/Scripts/Slider.js

this would adding support for touch events:
