Recently, I needed to change the Thumb's Template. I want to change its shape to a Triangle like so. I used a Path as its ControlTemplate. Here's the code:
<Thumb
Width="100"
Height="30"
HorizontalAlignment="Left"
VerticalAlignment="Top">
<Thumb.Template>
<ControlTemplate>
<Path Fill="Red">
<Path.Data>
<PathGeometry>
<PathFigure>
<PolyLineSegment>
<PolyLineSegment.Points>
<PointCollection>
<Point X="0" Y="0" />
<Point X="TemplateBinding Width" Y="TemplateBinding Height" />
<Point X="0" Y="TemplateBinding Height" />
</PointCollection>
</PolyLineSegment.Points>
</PolyLineSegment>
</PathFigure>
</PathGeometry>
</Path.Data>
</Path>
</ControlTemplate>
</Thumb.Template>
</Thumb>
You can see that I tried to bind PolyLineSegment.Points to Thumb's Width and Height.
But Visual Studio throws an error:
"Error Object of type 'System.Windows.TemplateBindingExpression'
cannot be converted to type 'System.Double'."
I don't know why it can't work. Can anyone give me a hint?
Update:
I found it's because Point.X or Point.Y is not Dependency Property. So that's why binding doesn't work.
I resolve this question by binding to LineSegment.This question is Closed.
