Hi Infragistics,

We're using the latest 14.2 Service Release and have discovered the following issue.

A Style has been defined to accept a valid range, in this case a year...

<Style x:Key="ValidatedXamNumericInputYear" TargetType="{x:Type ig:XamNumericInput}">

    <Setter Property="Width" Value="60"/>

    <Setter Property="ValueTypeName" Value="Int32"/>

    <Setter Property="SpinButtonDisplayMode" Value="Always"/>

    <Setter Property="PromptChar" Value=""/>

    <Setter Property="NullText" Value="{Binding Source={x:Static sys:DateTime.Today}, Path=Year}"/>

    <Setter Property="InvalidValueBehavior" Value="RevertValue"/>

    <Setter Property="ValueConstraint">

        <Setter.Value>

            <ig:ValueConstraint ValidateAsType="Integer32" MinInclusive="1982" MaxInclusive="2100"/>

        </Setter.Value>

    </Setter>

</Style>

If the contents of the input is then cleared\deleted and a valid number re-entered, the ErrorTemplate remains...

The control XMAL is...

<ig:XamNumericInput Style="{StaticResource ValidatedXamNumericInputYear}" Value="{Binding Path=<ViewModelProperty>, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True, ValidatesOnExceptions=True}"/>

I believe there is also a second issue that is linked.

The documentation states that the Value property will only be updated if the value is valid. In the case of the above entering 1 (for example) still updates the Value property even though it's invalid. This causes issues as the ViewModelProperty is then updated with an incorrect value.
