WPF XamNumericEditor binded to Slider

Question

I have a XamNumeric editor and a Slider to ease the percentage input.

The problem is that as soon as the user changes the value with the slider, the spin buttons in the editor get disabled .

I have the following xaml:

<InfragisticsWpf:XamNumericEditor x:Name="PercentEditor"
    Value="{Binding Percent, Mode=TwoWay}"                        
    ValueType="{x:Type System:Decimal}"
    Mask="nnn %"
    SpinButtonDisplayMode="Always">
    <InfragisticsWpf:XamNumericEditor.ValueConstraint>
        <InfragisticsWpf:ValueConstraint MinInclusive="0" MaxInclusive="100"/>
    </InfragisticsWpf:XamNumericEditor.ValueConstraint>
</InfragisticsWpf:XamNumericEditor>
<Slider 
    Value="{Binding ElementName=PercentEditor, Path=Value, Mode=TwoWay, Converter={StaticResource DoubleToDecimalConverter}}" 
    Minimum="0" 
    Maximum="100"                        
    IsSnapToTickEnabled="True" 
    VerticalContentAlignment="Center"
    VerticalAlignment="Center"
    TickFrequency="5">                      
</Slider>

Any ideas?

Answer 1

Ater some more debugging I have found a solution. The problem with the XamNumericEditor is that on the binding from the other controls it sets the carret poistion on the end of the visible value (% in my case) that's why the spin buttons do not work. To correct the problem I added the following handler:

 void NumericEditorOnGotFocus(object sender, RoutedEventArgs e) { var numericEditor = sender as XamNumericEditor; if (numericEditor != null) { var text = numericEditor.Text; var numberMatch = Regex.Match(text, @"\\d"); if (numberMatch.Success) { numericEditor.SelectionStart = numberMatch.Index; } } } 

I know this is not the best idea as I had add the handler in the code behind. I would prefer to have a solution directly in the Xaml file, but this solves the issue.
