Custom slider with an image or path_问答_开发者

I have a slider in my WP7 app that I would like to restyle. Im having a problem with default template

I made something like this but I cannot "bind" the thumb to the value.

      <Style x:Key="ThumbStyle1" TargetType="Thumb">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Thumb">
                    <Grid >
                        <Path Data="M13.832941,48.001114 L-0.00066526519,15.584446 L-0.1685528,3.1627214 L46.375076,3.1882343 L46.59383,15.594595 L33.375225,48.063122 z" Fill="#FF6D6D74" Margin="-0.668,2.662,0.906,-0.562" Stretch="Fill" Stroke="Black" UseLayoutRounding="False"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <ControlTemplate x:Key="tempoSliderControlTemplate" TargetType="Slider" >
        <Grid>
            <Rectangle Fill="#FF6D6D74" Margin="25,0,25,0" Stroke="Black"/>
            <Thumb x:Name="VerticalThumb" Width="50" Height="50" Style="{StaticResource ThumbStyle1}" RenderTran开发者_如何学CsformOrigin="0.5,0.5" CacheMode="BitmapCache"/>
        </Grid>
    </ControlTemplate>

to move it up and down.

Your template for the Slider has a pretty big lack of behavior. It draws itself, but has no triggers to define reactions to user clicks / drags, etc.

If you want to customize the look of the slider, I would suggest that you start with the original template and customize it. To do this, download the app Show Me The Templates!, extract the template to your project, then start customizing the thumb.

I hope this was helpful.

Edit: This is wrong. This only works in WPF. In Silverlight, the tool I'd recommend is Blend OR you can use Visual Studio's "Extract to Resource" feature on the template: Link

Edit Edit: I modified the builtin slider template to include your thumb style as a reference to the type of system of small tweaks you should go for rather than a "rip and replace".
