This is my current XAML.
<StackPanel Orientation="Horizontal" Grid.Column="3" Grid.Row="1">
<Label Content="Allocated:" FontSize="14"/>
<Label Content="{Binding AllocatedUnits, Mode=OneWay, ValidatesOnDataErrors=True}" ContentStringFormat="N0" FontSize="14"/>
</StackPanel>
How would I change this so that the red validation rectangle is around the whole text instead of just the number. (I will accept throwing away the stack panel entirely and doing something else.
A string-formatted binding would probably do the trick in this case, but that wasn't available in .NET 3.0 (in case you're still using that version!). If you can use it, you'd only need a single label control (so you can ditch both the other label and the stackpanel, and your validation border will wrap all the text in the remaining label).
EDIT: as per Jonathan's comment, it seems you need two attributes to do this on a content control...
Use something like this for your binding:
Content="{Binding AllocatedUnits, ValidatesOnDataErrors=true}" ContentStringFormat="Allocated: {0}"
MSDN documentation is here.

If I put the Column where the toolbar is hosted to be very big (800) then all the text is visible:
but if I put a smaller column this happens:
But I cannot understand why:
<DataTemplate x:Key="IconFilterButton">
<StackPanel Orientation="Horizontal">
<TextBlock
VerticalAlignment="Center"
Style="{StaticResource LargeIconStyle}"
Text="{Binding}" />
<TextBlock
Margin="6,0,0,0"
VerticalAlignment="Center"
DataContext="{Binding}"
Style="{StaticResource BodyTextStyle}"
Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ToggleButton}, Path=Tag}" />
</StackPanel>
</DataTemplate>
and here the definition
<ToggleButton
x:Name="DFilter"
Click="Filtering_Click"
Content=""
ContentTemplate="{StaticResource IconFilterButton}"
Tag="1d"
/>
<ToggleButton
x:Name="WFilter"
Click="Filtering_Click"
Content=""
ContentTemplate="{StaticResource IconFilterButton}"
Tag="1w"
/>
Even worst if I click on the button once they are out:
and then the text is visible but is wrong as the TextBlock is not considered in the object size:
The WPF ToolBar control uses a custom panel for the overflow Popup. In many styles, the ToolBarOverFlowPanel has a property WrapWidth set to a static value like 200. This determines how many items can be displayed before it wraps to another row in the popup.
I've created custom styling for this control and have found that the ToolBarOverFlowPanel used internally is buggy. That's probably the source of your problem.
You can re-template the ToolBar and wire-up a different value for WrapWidth to try to fix the issue, but my guess is that you'll still run into layout problems.
Otherwise, you might consider making your own replacement control.
I recently wrote my first custom control, an autocomplete textbox. Its Controltemplate consists of something like this
<Grid >
<Border/>
<TextBlock x:Name="Label"/>
<TextBox x:Name="TextLabel"/>
</Grid>
The first Textblock is used as a Label, the second one shows the content. The TextLabel binds on an Object, let's call it Customer If the underlying search doesn't find a Customer object, I want to show the errortemplate. When defining the TextLabel like this
<TextBox x:Name="PART_Editor"
HorizontalAlignment="Stretch"
VerticalAlignment="Center"
Validation.ErrorTemplate="{DynamicResource ValidationErrorTemplate}"
Style="{StaticResource TransparentTextBoxStyle}"
Text="{Binding Path=Text, RelativeSource={RelativeSource Mode=TemplatedParent},
Mode=TwoWay, ValidatesOnNotifyDataErrors=True,
NotifyOnValidationError=True,
ValidatesOnDataErrors=True,
UpdateSourceTrigger=PropertyChanged}" >
</TextBox>
the Validation is made and the error template of the textbox is shown. Unfortunately the Red Border is only around the inner TextBox and not around the whole custom control which looks just not good.
I was wondering how to achieve two things:
How can the ErrorTemplate of the CustomControl be triggered when one of the child-validations fail?
Do I have to specify all these NotifyOnValidationerror properties or is it possible to catch all errors on entity level and show the same ErrorTemplate

I'm displaying a series of messages (like emails) on a Grid:
<layout:TransitioningContentControl Name="tccCmdMessage" Margin="0,4">
<layout:TransitioningContentControl.ContentTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Title}" FontWeight="SemiBold" />
<TextBlock Name="tbCmdMessage" Text="{Binding Message}" TextTrimming="WordEllipsis" />
</StackPanel>
</DataTemplate>
</layout:TransitioningContentControl.ContentTemplate>
</layout:TransitioningContentControl>
However, the tbCmdMessage never displays. If I remove the TextTrimming (or change it to None) it works. Alternatively if I don't use a ContentControl parent it also works.
Any ideas?
Take a look at this link: http://social.msdn.microsoft.com/Forums/eu/wpf/thread/30fd3279-7bc8-424f-9ee6-41b9f9589a1a.
I suppose explicitly specifying the Width (or MaxWidth) of the StackPanel can make the texts trimmed. You can also try to use another type of container, like Grid.

I have a page in my WP7 app consisting of a TextBox beside a ListPicker. In their default modes, they don't line up properly; the ListPicker has a different padding to the TextBox, and its height is also different.
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<StackPanel Orientation="Horizontal">
<TextBox HorizontalAlignment="Left" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top"/>
<toolkit:ListPicker Width="170" ItemsSource="{Binding l}" Style="{StaticResource ListPickerStyle1}" VerticalAlignment="Top"/>
</StackPanel>
</Grid>
Manually tweaking the ListPicker's template to fit in correctly here is tricky and error prone. For example, when its height is adjusted, the caption (i.e. the text of the selected item) is no longer in the centre of the component.
My app is currently failing MS app review because the components are not all the same height.
Is there an easy way for me to set the toolkit:ListPicker to have the same appearance as a TextBox?
The simplest solution will be to take a copy of the the default style and tweak that using Blend to be exactly how you want it to look. This will take a little trial and error to sort out.
You can then use the implicit styling rules to apply it to all ListPickers without having to explicitly set the style on each instance:
<Style x:Key="MyListPickerStyle
TargetType="toolkit:ListPicker>
.... your tweaks here
</Style>
<Style TargetType="toolkit:ListPicker"
BasedOn="{StaticResource MyListPickerStyle}" />
It may be easier to tweak the TextBox Style of course :)
Ok, sounds odd, and there's likely a better way, but I haven't seen it yet.
What I'm trying to do is restyle a ListPicker under Windows Phone 7.
What I need is to
get rid of the header (that's easy, just define a null ListPicker.HeaderTemplate).
Force the picker to always go to full mode when clicked (again, easy, just set the ItemCountThreshold to 1).
Restyle the itemtemplate used when in FullMode (again, easy, just define a FullModeItemTemplate)
Incorporate the ListPicker's "HEADER" property value into the ItemTemplate (since only one item will ever show, i need the header text "embedded" within the one item).
It's that number 4 that I can't seem to get.
I've defined a listpicker like so (i'm directly defining the templates inline instead of in resources for now, just to keep things simple).
<phonekit:ListPicker Header="Header Text" x:Name="ListOfSounds"
SelectedItem="{Binding Path=DepartureChime, Mode=TwoWay, Converter={StaticResource EnumDescriptionToStringConverter}}"
ItemCountThreshold="1">
<phonekit:ListPicker.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Background="Transparent">
<TextBlock Text="{TemplateBinding Header}" />
<TextBlock Text="{Binding}" />
<TextBlock Text=">" />
</StackPanel>
</DataTemplate>
</phonekit:ListPicker.ItemTemplate>
Ignoring all the obvious formatting bits for now, the problem I'm having is that I can't use {TemplateBinding Header} from within a datatemplate. I've used it from a ControlTemplate no problem.
The result of this ItemTemplate should be an item displayed such as
{TextOfHeader}{Content of selected Item}>
I'm just not sure how to go about getting at a property of the templated control (the listpicker in this case).
Any ideas?
Take advantages of RelativeSource:
<TextBlock Text="{Binding Path=Header, RelativeSource={RelativeSource AncestorType={x:Type phonekit:ListPicker}}}" />
