Answer 1

i had solved the problem by this code

<chartingToolkit:LineSeries.DataPointStyle>
    <Style TargetType="chartingToolkit:DataPoint">
        <Setter Property="Background" Value="#0077CC" />
        <Setter Property="BorderBrush" Value="White"/>
        <Setter Property="BorderThickness" Value="2"/>
        <Setter Property="IsTabStop" Value="False"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="chartingToolkit:LineDataPoint">
                    <Grid x:Name="Root" Opacity="1">
                        <ToolTipService.ToolTip>
                            <StackPanel Margin="2,2,2,2">
                                <ContentControl Content="{TemplateBinding IndependentValue}" ContentStringFormat="Date : {0}"/>
                                <ContentControl Content="{TemplateBinding DependentValue}" ContentStringFormat="Count : {0:###,###,###}"/>
                            </StackPanel>
                        </ToolTipService.ToolTip>
                        <Ellipse StrokeThickness="{TemplateBinding BorderThickness}" Stroke="{TemplateBinding BorderBrush}" Fill="{TemplateBinding Background}"/>

If anyone doesn't understand this solution, it is because the question author tried to use a TemplateBinding outside of a ControlTemplate, where this special kind of binding is supposed to be used. This solution was therefore, to use it within a ControlTemplate. – Dordrecht

Answer 2

Just in case someone lands here searching for the error message, I was getting it simply because I was mistakenly using x:Static instead of StaticResource to access a locally declared resource.

Hope this helps someone down the road.

My head hurts from banging it against my keyboard after reading your answer. Made my day :-) – Memoried

In my case it was a missing TargetType prop on a style declaration... – Autogenesis

Answer 3

Just incase someone needs glasses, like me..

Before (failing XAML)

<Setter Property="Command" Value="{x:Static local:Map:ZoomCommand}" />

After (fixed XAML)

<Setter Property="Command" Value="{x:Static local:Map.ZoomCommand}" />

I just needed to change the colon to a dot.

Answer 4

You are seeing this error because you are using a TemplateBinding outside of a control template. You can only use that binding type within a control template.

Without adding more detail to the question, I'm not sure what exactly you are trying to achieve.

You can see an example of appropriate TemplateBinding use at this other answer.
