I'm applying this style to an infragistics control XamDateTimeEditor. The new error icon displays as expected.

issue: The original error style is still displaying when a validation error occurs. Thus making the control to have two error icon styles.

<Style TargetType="{x:Type XamDateTimeEditor}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Control}">
<DockPanel>
<Border Background="Red" Width="25" Height="25" CornerRadius="10">
<TextBlock Text="Error" VerticalAlignment="Center" HorizontalAlignment="Center" FontWeight="Bold" Foreground="White" />
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Hello Michael,

As I indicated in my previous reply, The original error style is still displaying when a validation error occurs. Thus making the control to have two error icon styles.

You can find the style I'm using in my previous comment.

I appreciate a prompt response.

<Style x:Key="ErrStyle" TargetType="{x:Type ig:XamDateTimeEditor}">

<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<DockPanel LastChildFill="True">
<Border Background="Red"
DockPanel.Dock="Right"
Margin="5,0,0,0"
Width="20"
Height="20"
CornerRadius="5"
ToolTip="{Binding AdornedElement.(Validation.Errors).CurrentItem.ErrorContent, ElementName=customAdorner}">
<TextBlock Text="!"
VerticalAlignment="Center"
HorizontalAlignment="Center"
FontWeight="Bold"
Foreground="White" />
</Border>
<AdornedElementPlaceholder x:Name="customAdorner"
VerticalAlignment="Center">
<Border BorderBrush="red"
BorderThickness="1" />
</AdornedElementPlaceholder>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Thank you

Hi Micheal,

Any advise on this one.

Thanks,

Hello User 101,

Thank you for following up. Please send a screenshot. It sounds like the datagrid validation is also appearing with the editor.

Micheal, I have no datagrid involved. When I have copied the code over I was trying different things, I forgot to revert.

I have the XamDateTimeInput sitting in a StackPanel.

The error icon messages appearing are the same. Which tells me that the error provider Template is not overridden. It looks like it is adding another template to this one.

Hello User 101,

Thank you for following up. Okay then the style will probably need to be embedded within the control instead as a higher level resource on the window for example. That way the control won't override your new style. I will work on implementing this today.

Let me know if you have any questions.

Hello User 101,

I attached a sample. However there appears to be some confusion about which control you are trying to restyle. I do not recommend using the XamDateTimeInput since it doesn't support customized error validation in the manner in which you are showing. Using a ViewModel to provide a customized validation error messages is the best advice.

Let me know if you have any questions.
