I was playing with progress bar customization in Silverlight application. What I want to reach is to have progress bar label to show current its state in the following format:
"Value / Maximum". So, user will see what is the current value, and what is the maximum possible value. Here is a style for progress bar I use:
<Style x:Key="ProgressBarStyle" TargetType="ProgressBar">
<Setter Property="Width" Value="97.21" />
<Setter Property="Height" Value="19" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ProgressBar">
<Canvas x:Name="LevelField" Width="99" Height="21">
...
<TextBlock ... DataContext="{TemplateBinding Value}" Text="{Binding Converter={StaticResource DecNumberToStringConverter}}"/>
</Canvas>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
The way I want to implement this, is to have a value converter, that will convert current value and maximum possible into the proper string. It does work properly, if it is written like above. However, I also need to provide ConverterParameter for Convertor, but not sure how to make it. When I write like this: , ConvertParameter={Binding Maximum}, it shows error on start, that Text attribute is not found in TextBlock. I was also trying to set DataContext as {RelativeSource Self}, but then it didn't displays error that DataContext attribute is not found.
How to make the described progress bar label properly?
