RDLC - Cells Empty on Tablix on Subreport - even through rows are there - rdlc

Hi I have a RDLC report with 3 sub reports. Everything works OK - except the 3rd sub report - which just displays blank data - it does display the correct number of rows however.
There is no connection or parameters associated with the parent report. It works ok as a single report - just not as a subreport.
I have tried all combinations of elements, grouping hiding, setting growth on off - allowing\disallowing increase etc...
Any suggestions anyone?
Code for subreport

How to center the text in an Avalonia DataGrid column header?

How can I cause the DataGrid column headers to be centered instead of left-aligned?
In particular, I want to center just the 3rd column.

(I used to use DNOA!). Anyway ... here you go.
If memory serves this is more or less the default style, I think I've pulled out any of my specifics so should just drop in to your application. Remember to pull in the Default DataGrid styles first.

<Setter Property="Data" Value="{StaticResource DataGridSortIconDescendingPath}" />
</Style>
The key line relative to this question is:
<Setter Property="HorizontalContentAlignment" Value="Center" />
To only do one column, things would get a little more involved as above is a globally applied style through the Selector=Type (same as WPF {Type:xxx} style convention). So you could look at making that one column "targetable" somehow so a Selector= would only hit that column.
Off the top of my head, you'd have to turn off auto column generation on your DataGrid instance, manually generate the columns and give that one column a name, such as "immagonnabecentered", then selectors should just target this single column.
So create columns like:
<controls:DataGrid.Columns>
<DataGridTextColumn Header="File Name" Binding="{Binding FileName}" SortMemberPath="FileName"/>
<DataGridTextColumn x:Name="immagonnabecentered" Header="File Name" Binding="{Binding FileName}" SortMemberPath="FileName"/>
...
</controls:DataGrid.Columns>
Then update the style selector on the Style to hit this one column.
<Style Selector="#immagonnabecentered">
<Style Selector="DataGridColumnHeader#immagonnabecentered">

Can't get FontSize for labels to work in ResourceDictionary when using OnPlatform

When using <Style TargetType="Label"> I cant get FontSize to work with NamedSize.
Using Xamarin.Forms version : 3.4.0.1008975
Working :
<Style TargetType="Label">
<Setter Property="FontSize" Value="Small" />
</Style>
NOT working :
<Style TargetType="Label">
<Setter Property="FontSize">
<Setter.Value>
<OnPlatform x:TypeArguments="x:String"
Android="Small"
iOS="Medium"/>
</Setter.Value>
</Setter>
</Style>
I have tried to change the TypeArguments to <OnPlatform x:TypeArguments="NamedSize" .../> with no success.
I am using other propertysetters with <OnPlatform .../> and they work as they should. Its just FontSize.

Any help ?

I Solved it , the error was in :
<Entry Grid.Row="0" Grid.Column="1" Placeholder="UserName"
Text="{Binding SelectedUser.UserName, Mode=TwoWay}"
x:Name="NameEntry" >
<Entry.Behaviors>
<local:MaxLengthValidator MaxLength="10" x:Name="nameValidator"/>
</Entry.Behaviors>
</Entry>
<Image Grid.Row="0" Grid.Column="2" x:Name="NameSucessErrorImage"
Style="{Binding Source={x:Reference nameValidator},
Path=IsValid,
Converter={StaticResource boolToStyleImage}}"/>
<Label Grid.Row="1" Grid.Column="1" Style="{Binding Source={x:Reference nameValidator},
Path=IsValid,
Converter={StaticResource boolToStyleName}}" />
I didn't define x:Name="nameValidator" at local:MaxLengthValidator tag to reference to Behavior in image and label tag.

How do you change the foreground color of a stackpanel in xaml

I have this in my App.xaml
<Style x:Key="ColorBlack" TargetType="StackPanel">
<Setter Property="TextElement.Foreground" Value="Black"></Setter>
</Style>
And this on a xaml page
<StackPanel Style="{StaticResource ColorBlack}"></StackPanel>
In the designer the color changes to black but when i run the application on a device it crashes and says it doesn't know the name ColorBlack.

You can try something like this :
<StackPanel>
<StackPanel.Resources>
<Style TargetType="{x:Type FrameworkElement}">
<Setter Property="TextBlock.Foreground" Value="Blue" />
</Style>
<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource {x:Type TextBlock}}" />
<Style TargetType="{x:Type Label}" BasedOn="{StaticResource {x:Type Label}}" />
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type FrameworkElement}}" />
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type TextBox}}" />
</StackPanel.Resources>
<TextBlock Text="TextBlock"/>
<Label Content="Label"/>
<Button Content="Button"/>
<TextBox Text="TextBox"/>
</StackPanel>

Bug or User error? Unable to set TextBlock's VerticalAlignment property to Center

Hmmm. . . I'm losing my mind. . . or am I?
I'm creating a WPF app for some basic data entry. I'm using textblocks to label the textboxes but ran into a snag. Why can't I vertically center the textblocks? I can't change the vertical alignment at all. Regardless of what I value I set on the property, the textblocks remain at the top. I want them centered! I can change the horizontal alignment no problem.
The contents of the XAML file, including the styles, are included below.

I am not 100% sure why it is not centering, probably has to do with the height set on the elements, but what you can do is apply a padding to the TextBlocks to get them centered with the TextBoxes.
