Hi,

I have this XAML

<Page
    x:Name="pageRoot"
    x:Class="GridViewTest.Main"
    DataContext="{Binding DefaultViewModel, RelativeSource={RelativeSource Self}}"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:GridViewTest"
    xmlns:common="using:GridViewTest.Common"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Page.Resources>
        <!-- TODO: Delete this line if the key AppName is declared in App.xaml -->
        <x:String x:Key="AppName">GridView Test</x:String>
        <ItemsPanelTemplate x:Key="StoreFrontGridItemsPanelTemplate">
            <ItemsWrapGrid MaximumRowsOrColumns="3"/>
        </ItemsPanelTemplate>
    </Page.Resources>

    <!--
        This grid acts as a root panel for the page that defines two rows:
        * Row 0 contains the back button and page title
        * Row 1 contains the rest of the page layout
    -->
    <Grid removed="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <Grid.ChildrenTransitions>
            <TransitionCollection>

            <RowDefinition Height="140"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <!-- Back button and page title -->
        <Grid>
            <Grid.ColumnDefinitions>

                        AutomationProperties.Name="Back"
                        AutomationProperties.AutomationId="BackButton"
                        AutomationProperties.ItemType="Navigation Button"/>
            <TextBlock x:Name="pageTitle" Text="{StaticResource AppName}" Style="{StaticResource HeaderTextBlockStyle}" Grid.Column="1" 
                        IsHitTestVisible="false" TextWrapping="NoWrap" VerticalAlignment="Bottom" Margin="0,0,30,40"/>
        </Grid>
        <GridView x:Name="Grd" Grid.Row="1" Height="70" HorizontalContentAlignment="Stretch"

                  CanDragItems="True" CanReorderItems="True" Width="500">
            <GridView.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto" />
                            <ColumnDefinition Width="Auto" />
                        </Grid.ColumnDefinitions>
                        <Image Source="{Binding Image}" Grid.Column="0"/>
                        <TextBlock Text="{Binding Title}" Margin="5,0,0,0" Grid.Column="1" TextWrapping="WrapWholeWords"/>
                    </Grid>
                </DataTemplate>
            </GridView.ItemTemplate>
        </GridView>
    </Grid>
</Page>

which gives me this output

that's strange because the TextBlock have the Width property which hinder the item to show the entire text. I'm stuck. Can anyone of you solve this problem?

Thanks!!
