Hello,

Basically I am positioning the cursor in the box mid way though a number and then just holding down backspace and I get an IndexOutOfRangeException which says "Index was outside the bounds of the array.". I do have a screencast of me creating the error if you need that.

Here is the xaml:

<telerik:RadMaskedCurrencyInput Grid.Row="5" Grid.Column="3" Value="{ Binding BgsStepBase, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True, ValidatesOnExceptions=True}" Style="{ StaticResource StandardRadMaskedCurrencyInput}" Validation.ErrorTemplate="{ StaticResource RadMaskedCurrencyInputErrorTemplate}" IsClearButtonVisible="True" IsReadOnly="{Binding IsBgsFieldEnabled, Converter={StaticResource NotConverter}}" FormatString="n0" />

The bound value is decimal? (nullable decimal).

The stack trace is:

Hi Alex,

I tested the snippet that you provided with our latest official release on our side and it seems that the code works as expected. I would like to know which version of our controls you use.

on the other hand, is it possible for you to try to reproduce the reported issue in a separate project and send it over? By doing so I will be able to fully understand your scenario and investigate the reasons behind the issue.

Thank you for your kind cooperation.

Pavel R. Pavlov

Hello


We have the same problem with the latest version of telerik MaskedInputNumericControl(2013.3.1016.40).
Properties from style:
<Setter Property="IsTabStop" Value="False" />
<Setter Property="UpdateValueEvent" Value="LostFocus"/>
<Setter Property="TextMode" Value="PlainText"/>
        <Setter Property="IsClearButtonVisible" Value="False"/>
        <Setter Property="Placeholder" Value="_"/>
        <Setter Property="Mask" Value=""/>
        <Setter Property="FontWeight" Value="Normal"/>
        <Setter Property="AcceptsReturn" Value="False"/>
        <Setter Property="SelectionOnFocus" Value="Unchanged"/>
        <Setter Property="SpinMode" Value="None"/>
        <Setter Property="InputBehavior" Value="Insert"/>
        <Setter Property="SectionsNavigationMode" Value="None"/>


Example:
<telerik:RadMaskedNumericInput x:Name="edtTextBoxControl" Margin="5,0,3,3" MinWidth="50" MaxWidth="50"
                                      HorizontalAlignment="Left"
 VerticalAlignment="Center"
                                      Value="{Binding Value,UpdateSourceTrigger=PropertyChanged}"/>
wwhere Value is of type interger .


Steps:

- Enter large value - (9.86767676767676E+76)
- Press Backspace
- Get exception

Hello

Some details:

- Enter value 8.77777888888888E+88
- Move caret to the end of text input
- Press Backspace and you will get error


The bug can be duplicated only if UpdateValueEvent=PropertyChanged

Hi Jason and Alex,

 We managed to reproduce this Exception thanks to the provided info. We logged it in our PITS where you can track its status. We will do our best to have it fixed for the Service Pack next month.
