Frustration trying to bind NumberOfTickMarks in XamNumericSlider
posted

I have a very simple slider shown below.  I can bind properties directly on the slider object to my view-model, but no matter how I try to bind the NumberOfTickMarks property in my ig:SliderTickMarks object, I get the following error in my Output:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=DataContext.SliderNumTickMarks; DataItem=null; target element is 'SliderTickMarks' (HashCode=23629823); target property is 'NumberOfTickMarks' (type 'Int32')

I have tried setting the binding multiple ways.  As you can see in the other properties, they bind to my view-model without a problem as it is the datacontext for my usercontrol.  What am I doing wrong?

 

<ig:XamNumericSlider x:Name="DaySlider" Grid.Row="4" 
                    Margin="3,1,3,1" Orientation="Vertical" 
                     IsDirectionReversed="True"
                     Value="{Binding TotalDaysOnChart}"
                     MinValue="{Binding SliderLowerBound}" 
                     MaxValue="{Binding SliderUpperBound}" 
                     SmallChange="1">
 
        <ig:XamNumericSlider.TickMarks>
             <ig:SliderTickMarks NumberOfTickMarks="
             {Binding Path=DataContext.SliderNumTickMarks, 
              RelativeSource={RelativeSource AncestorType=
                     {x:Type UserControl}}}" />
        </ig:XamNumericSlider.TickMarks>
 
</ig:XamNumericSlider>
