I have a SfRangeSlider defined as follows:

<?xml version="1.0" encoding="UTF-8"?>
    Title             ="Install Device"
    xmlns            ="http://xamarin.com/schemas/2014/forms"
    xmlns:x           ="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class           ="Smart.Pages.RangeDemoPage"
    xmlns:range       ="clr-namespace:Syncfusion.SfRangeSlider.XForms;assembly=Syncfusion.SfRangeSlider.XForms"
                x:Name       ="sfSliderOrientation"
                Grid.Row     ="4"
                Grid.Column  ="1"
                WidthRequest ="100"
                Minimum      ="0"
                Maximum      ="90"
                Value        ="{Binding Orientation}"
                ShowRange    ="false"
                SnapsTo      ="Ticks"
                Orientation  ="Horizontal"

On Android, it's positioning the thumb correctly, but on iOS the thumb is not being positioned correctly -it is just off to the right. I've attached screenshots from Android and iOS.

Is this a known problem?

I have downloaded the Service Pack, but this has not fixed the problem.

I've attached a sample which demonstrates the problem. Note that I based the solution/projects on the GaugeSampleTest, so some of the projects are still name GaugeSampleTest!

Hi James,

We have tested the provided sample with 2015 Volume 4 Service pack 2 assemblies (13.4451.0.58) and we were unable to reproduce the reported issue at our end .We have attached a screenshot that was captured while testing the provided sample which is available in the below link.

Please ensure that the assembly version referred is the same version that we provided(13.4451.0.58).

Hi Hemelatha,
Thank you for your reply.

Looking at your attached screenshot, I think that it actually demonstrates the problem. All the sliders are over at the maximum value. What happens if you bind to a value mid-way between the minimum and maximum? Do you see the slider thumbs move to the middle?
