  Hi chou,
  
  I'd like to suggest you use our new RadMaskedNumericInput control which is part of the RadMaskedInput suite. For your particular case, you will have to add a little bit of code-behind to achieve your exact specifications.
  
  

  <telerik:RadMaskedNumericInput Mask="#6" FormatString="{}{0:######}"

          ValueChanged="RadMaskedNumericInput_ValueChanged"

          AutoFillNumberGroupSeparators="False" Placeholder=" "

          HorizontalAlignment="Stretch" />

  
  

  private void RadMaskedNumericInput_ValueChanged(object sender, Telerik.Windows.RadRoutedEventArgs e)

  {

      RadMaskedNumericInput input = (sender as RadMaskedNumericInput);

      int selStart = input.SelectionStart;

      if (input.Value > 999)

      {

          input.AutoFillNumberGroupSeparators = true;

      }

      else

      {

          input.AutoFillNumberGroupSeparators = false;

      }

      input.SelectionStart = selStart + 1;

  }

  
  The result of the above can be seen here. Let me know if this helps.
  
  Kind regards,
