Thanks All for your contribution.
I have created a application for windows 10 (uwp) devices. I´m using the windows appstudio "designer". Now, I have to update the source code by a combobox and the correct eventhandler.
The combobox items contains different urls. After the selection changed, I have to parse entries from a url.

"MyGrid" has DataContext (assigned in code behind) with three public
properties:
'Images'
'h1'
'h2'
Problem with the code below is that bindings to 'h1' and 'h2' are set to element of 'Images' collection but they should be set to binding of 'MyGrid'.
my code
<Grid x:Name="MyGrid">
<FlipView ItemsSource="{Binding Images}">
<FlipView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="{Binding h1}"></RowDefinition>
<RowDefinition Height="{Binding h2}"></RowDefinition>
</Grid.RowDefinitions>
<Image Grid.Row="0" Source="{Binding}"></Image>
<TextBlock Grid.Row="1" Text="AAA"></TextBlock>
</Grid>
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
</Grid>
How should I change 'h1' and 'h2' bindings?
Thank you!
Use ElementName to specify binding source:
<Grid x:Name="MyGrid">
<FlipView ItemsSource="{Binding Images}">
<FlipView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="{Binding ElementName=MyGrid, Path=DataContext.h1}"></RowDefinition>
<RowDefinition Height="{Binding ElementName=MyGrid, Path=DataContext.h2}"></RowDefinition>
</Grid.RowDefinitions>
<Image Grid.Row="0"
Source="{Binding}"></Image>
<TextBlock Grid.Row="1"
Text="AAA"></TextBlock>
</Grid>
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
</Grid>
At my wits end with trying to get a TabControl and TabItems to fill a NavigationPage/Frame.
I have a MasterPage, with a Frame, that will get swapped out for different Pages, which are comprised of UserControls.
The problem I am having is that the TabControl is cutting off the UserControl and not auto sizing properly. Below is an image and the source for the Pages and Controls.

I have a listbox with a textbox
The textbox is defined in a datatemplate that ends like this
<TextBlock Grid.Row="4" Grid.Column="0" Text="Note"></TextBlock>
<TextBox Height="Auto" Grid.Row="4" Grid.Column="1"
Text="{Binding PartData.Note}" AcceptsReturn="True" TextWrapping="Wrap" >
</TextBox>
</Grid>
I want the textbox to expand when the user enters multiple rows but it doesnt. The rowdefintion height is set to *
I've tried your sample with this code, and it works (use Shift-Enter to start a new row inside TextBox)
<Window x:Class="TextBoxWrap.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<ListBox Height="140" ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="1" Grid.Column="0" Text="Note"/>
<TextBox Margin ="10, 0,0,0" Height="Auto" Grid.Row="1" Grid.Column="1" Text="{Binding Count}"
AcceptsReturn="True" TextWrapping="Wrap" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Window>
You need to add
VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch"
to TextBox so it takes all available space.
