Hi Alberto,  
 
We would like to inform you that we give patch only in our main release or SP release version only. But 17.1.0.50 is a weekly nuget version. So that we have given the patch in 17.1.0.47 (Vol1 SP 1) version.

hi,
the scenario is easy: i have 1 slider and 1 textview that shows the slider value using this function
private void SfRangeSliderX_ValueChanged(object sender, ValueChangedEventArgs e)
        {
            tvTest.Text = ((int)e.Value).ToString();
        }

just this.

ok,
i find how to test and see my issue.
from an activity to new activity and then come back (using protected override void OnActivityResult)
Now,i can notice that the slider has a different color (light gray instead of red) and now if i use the slider i have the exception.

please check also tooltip size since on some device tooltip doesn't fit its content (eg it shows 3 for 35, 2 for 23 ec..)

this is urgent fix since this component is unusable !!!!!!!!

hi,
finally seems it works but i think you should check better since is there the horizontal line that when i come back to the activity has a light gray insted of a dark one.
no exception, it works but maybe something should  be still fixed.
please, for the future do more test for your components ..... it is not possbible having this issue in a production version

hi,
color fixed when there is just one Thumb.
But when i use it as a range with 2 ThumbSize, the left one part of horizontal line is dark and the right one light gray.
No exception, control is working, just a graphics issue.
thanks

issue on tooltip for oneplus 6t still there

MK Muneesh Kumar G Syncfusion Team June 24, 2019 11:20 AM UTC

Hi Alberto, 
 
Query1: When I use it as a range with 2 ThumbSize, the left one part of a horizontal line is dark and the right one light gray 
 
We have validated your query, to resolve this issue, you can set custom color (ex. light gray) as Track color in the sample level as like below code snippet. 
 
 
range.TrackColor = Color.LightGray; 
 
Query 2: Issue on the tooltip for one plus 6t still there 
 
As we mentioned in the previous update, we were not able to reproduce the reported issue in one plus  6T device at our end. 
 
Could you please send video or screenshot or send code snippet to reproduce the reported issue? 
 
This would be helpful for us to give better solution in this.  
 
Regards,  
Muneesh Kumar G.
