Databind issue on NumericUpDown

[Cihan]

Hi,

I would like to use a numeric updown on wp8 application. however I couldn't manage to get the updated value on the control...

When the field is updated, I just re-populate a RadDataBoundListBox. If I use a textblock instead of numericupdown control in this radDataboundListBox, I can see the updated value on textblock but if I use numericupdown, it still shows the previous value.. Here is my dataTemplate that I use for both controls

<DataTemplate x:Key="DataBoundListBoxItemTemplate">

     <Grid Margin="0,0,0,12">

         <Grid.ColumnDefinitions>

             <ColumnDefinition/>

             <ColumnDefinition Width="Auto"/>

         </Grid.ColumnDefinitions>

         <StackPanel Margin="0,-14,0,0">

             <Controls:RadNumericUpDown MaxValue="10" MinValue="0" Value="{Binding quantityField}" />

             <TextBlock FontSize="{StaticResource PhoneFontSizeExtraLarge}" FontFamily="{StaticResource PhoneFontFamilySemiLight}" Text="{Binding quantityField}" TextWrapping="Wrap"/>

         </StackPanel>

     </Grid>

</DataTemplate>

 

Thanks in advance,

Cihan

Hi Cihan,

Thanks for writing.

By looking at your XAML code I cannot exactly say why this issue happens. It is possible for you to attach a sample project that reproduces the issue here so that we can take a look and see how to further assist you?

Hi Deyan,

I have the same problem than Cihan with the Silverlight RadNumericUpDown version 2013.3.1125.

Here a sample (a UI exemple is in attachment):

    <Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
         <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="Auto" />
        </Grid.ColumnDefinitions>
 
        <TextBlock Text="Enter a value:" />
        <telerik:RadNumericUpDown x:Name="NumericValue1" Grid.Column="1" Width="100" ShowButtons="False"  />
 
        <TextBlock Grid.Row="1" Grid.Column="0" Text="Value entered:" />
        <TextBlock Grid.Row="1" Grid.Column="1" Text="{Binding Value, ElementName=NumericValue1}" />
        
    </Grid>

Hello Yvan,

Please redirect RadControls for Silverlight questions to the corresponding forums. Here only the RadControls for Windows Phone are supported.
