RangeSlider's Value property not updated when using ValueChanging event

[Keshav Kumar]

Suppose I bound RangeSlider's Value propery to some property in ViewModel & I use this ViewModel property in the RangeSlider's ValueChanging event-handler, then ViewModel property remains unchanged.

As a workaround, I've to use ValueEventArgs.Value property to get value.

I wanted RangeSlider's Value property to be changed, so that I can easily bind Value property to some property in ViewModel (MVVM).

Has this issue been fixed.  i'm experiencing this issue with the current release (15.3.0.33).  The code I''m using is below.  I'm simply browsing to a page and expecting the value of the SfRangeSlider (which is used in single value form) to be updated.  It is not.  I've tried moving the DoubleSetToAValueOf40 value to the TickFrequency and StepFrequency, where it binds properly.  

<xForms:SfRangeSlider

x:Name="rangeslider2" 

Value="{Binding DoubleSetToAValueOf40}"

Maximum="150"

Orientation="Horizontal" 

TickPlacement="Inline"

ToolTipPlacement="TopLeft" 

ShowRange="False"

KnobColor="Orange"

ValuePlacement="TopLeft"

TickFrequency="50"

StepFrequency="5"

BackgroundColor="Transparent"/>
