  I am trying to use the NumericUpDown but I need to format the displayed value so as to not show anything after the decimal, i.e. I want whole numbers only. I cannot seem to find a text format property, so how can I achieve this?
  
  Thanks,

  Hi Blair,
  
  To have integers you should set NumberFormatInfo.NumberDecimalDigits = 0 in case the ValueFormat property is set to Numeric. If you want to use integers for Percentage or Currency, you should change the ValueFormat property to the appropriate one, and then set the corresponding DecimalDigits property of NumberFormatInfo to 0.
  
  Please have a look at http://msdn.microsoft.com/en-us/library/system.globalization.numberformatinfo_properties.aspx where all format options are available.

  This seems a little convuluted to me.
  
  1. Because I can't just set a format in XAML using a string
  and
  2.
                     <telerik:RadNumericUpDown.NumberFormatInfo>
                          <globalization:NumberFormatInfo NumberDecimalDigits="0"/>
                      </telerik:RadNumericUpDown.NumberFormatInfo>
  doesn't seem to have any affect.
  
  While it may all well and good to set the value in C# code behind, this severely limits the usefulness of the control in DataTemplate situations.
  
  The documentation also mentions setting ValueFormat to custom, which doesn't appear to be an option in Q2 release of the controls.

  Hello Justin,
  
  I used the following XAML successfuly:
  

  <

  Window x:Class="RadComboBoxTestWpf.Window1"
      xmlns:n="clr-namespace:System.Globalization;assembly=mscorlib"
      xmlns:t="http://schemas.telerik.com/2008/xaml/presentation"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      Title="Window1" Height="300" Width="300">
      <Grid>
          <t:RadNumericUpDown SmallChange="1" Minimum="0" Maximum="100">
              <t:RadNumericUpDown.NumberFormatInfo>
                  <n:NumberFormatInfo NumberDecimalDigits="0" />
              </t:RadNumericUpDown.NumberFormatInfo>
          </t:RadNumericUpDown>
      </Grid>
  </Window>

  Am I missing something?
  
  Regarding the text for setting ValueFormat=Custom - this is a mistake, that will be fixed as soon as possible.

  Nope, you didn't miss anything. My code was identical to that except my namespaces were not n and t, they were globalization and telerik respectively, but that shouldn't make any difference.
  
  Mine was inside a DataTemplate which seems to make the difference.
  
  I have a sample project ready to go if you'd like me to email it to you.
  
  Regards
  
  Justin

  Hello Justin,
  
  I managed to reproduce and fix the problem. The upcoming service pack of RadControls for WPF will contain the fix. Thank you for your feedback, your points have been updated!

  Any chances of getting a timeframe for delivery of the service pack. This is something we'd like to use as soon as possible.

  I've recently upgraded to version RadControls_for_WPF_2010_1_0603_DEV.msi
  
  I have a RadNumericUpDown control inside a DataTemplate, that gets selected via a TemplateSelector, and the NumberFormatInfo seems to have no effect.  Is this problem back, or was it ever fixed in a non-service pack release?
  
  Following is my XAML code block that defines the RadNumericUpDown:
  
  

   

   

  <telerik:RadNumericUpDown Grid.Row="3" Grid.Column="1"

   

   

  VerticalAlignment="Center"

   

   

  HorizontalAlignment="Stretch"

   

   

  Foreground="Black"

   

   

  IsEnabled="{Binding ElementName=IsAssignedInspectorCheckBox, Path=IsChecked}"

   

   

  Value="{Binding Path=Response.ResponseNumeric, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"

   

   

  CustomUnit="{Binding ElementName=UnitLabel, Path=Content}"

   

   

  ValueChanged="NumericValue_Changed"

   

   

  ValueFormat="Numeric" SmallChange="1" LargeChange="50" Minimum="0" Maximum="2000000" >

   

   

   

  <telerik:RadNumericUpDown.NumberFormatInfo>

   

   

   

  <globalization:NumberFormatInfo NumberDecimalDigits="0" />

   

   

   

  </telerik:RadNumericUpDown.NumberFormatInfo>

   

   

   

  </telerik:RadNumericUpDown>
  
  Thanks

  Hi Jacquest,
  
  I had to remove some of your code in order to test the sample (the bindings to IsEnabled, Value and CustomUnit), but everything seems to work as expected. Could you please send me a simple application that can be used to observe the problem?
  
  By the way, you could set IsInteger=true on RadNumericUpDown to achieve the same effect, without declaring NumberFormatInfo.
