Answered Validation Result not shown

Hello,

I have a RadDatePicker whose SelectedValue is bound to a property of an object which implements IDataErrorInfo:

<telerik:RadDatePicker

telerik:StyleManager.Theme="Office_Black"

DataContext="{Binding ReceiptDateField}"

SelectedValue="{Binding SelectedDate, Mode=TwoWay, ValidatesOnDataErrors=True}"

DateTimeWatermarkContent="" DisplayFormat="Short"

Margin="296,196,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Height="24" Width="84"/>

If validation failes the RadDatePicker only has a red border but no red triangle in the upper right corner. Therefore it's not possible to see the error info.
Could you please fix this bug.

Greetings

Heiko

Hi Heiko Görig,
Unlike Silverligth there is no out of the box tooltip for WPF RadDatePicker. You can create easily a tooltip that will show the error using this code.

<Grid.Resources>

    <Style TargetType="{x:Type telerik:RadDateTimePicker}">

        <Style.Triggers>

            <Trigger Property="Validation.HasError" Value="true">

                <Setter Property="ToolTip"

        Value="{Binding RelativeSource={RelativeSource Self},

               Path=(Validation.Errors)[0].ErrorContent}"/>

            </Trigger>

        </Style.Triggers>

    </Style>

</Grid.Resources>

Hope this helps. If you have further questions please let me know.

Kind regards,
