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>
Hello,
I am just checking if you got this worked out or you still require any assistance or clarification on the matter.
Hi,
I am binding some properties of the slider and every thing works fine. But only NumberOfTickMarks are not binding. ie., binding value of NumberOfTickMarks is 20, but by default it takes 5 (It doesn't throw any error).
And i need one help. For some sliders i don't want TickMarks, how can i achieve this using binding (Actually my sliders are in list box template).
<ListBox ItemsSource="{Binding DataUtil}" VirtualizingStackPanel.VirtualizationMode="Recycling" > <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <ig:XamNumericRangeSlider /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate></ListBox>
Thanks
