Dealing with Value in UWP Rating (SfRating)

Setting the rated value

Value property is used to get or set the rate value in SfRating control.

<input:SfRating ItemsCount="5" Value="2" x:Name="rating"/>
rating.ItemsCount = 5;

rating.Value = 2;
rating.ItemsCount = 5

rating.Value = 2

Setting the rated value view

Previewing the rate

PreviewValue property is used to get the pointer over value in SfRating control, and this value is displayed as tool tip content.

Rating PreviewValue view

ValueChanged event

ValueChanged event fires whenever the value is changed in rating control. Event arguments contain old value and new value.

<input:SfRating ItemsCount="5" ValueChanged="rating_ValueChanged"/>
private void rating_ValueChanged(object sender, ValueChangedEventArgs e)

Private Sub rating_ValueChanged(ByVal sender As Object, ByVal e As ValueChangedEventArgs)

End Sub

Read only Rating control

SfRating can also restrict user from changing the rates in control using the IsReadOnly property. But preview value changes when pointer moves over the control.

<input:SfRating ItemsCount="5" Value="2" IsReadOnly="true" x:Name="rating"/>
rating.ItemsCount = 5;

rating.Value = 2;

rating.IsReadOnly = true;
rating.ItemsCount = 5

rating.Value = 2

rating.IsReadOnly = True
