带有标题和项模板列的Windows 8 XAML ListView应具有相同的动态

我正在使用带有Itemtemplate和Headertemplate的Listview.
两个模板都包含6个列.如果我为模板设置固定的列宽,一切都很好 – 如图1所示.
但我想为项目设置宽度为“自动” – 但后来我得到图2 …

怎么办呢？
是否可以使用c#设置标题列宽度？ – 或任何其他解决方案？

代码列表视图：

<ListView x:Name="DayanalyseListView" 
                      HorizontalAlignment="Center" 
                      VerticalAlignment="Top" 
                      ItemTemplate="{StaticResource DataTemplate}" 
                      HeaderTemplate="{StaticResource HeaderTemplate}">
            </ListView>

HeaderTemplate中：

<DataTemplate  x:Key="HeaderTemplate" >
        <Grid Height="36" Background="DarkGray" >
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="95"/>
                <ColumnDefinition Width="85"/>
                <ColumnDefinition Width="85"/>
                <ColumnDefinition Width="85"/>
                <ColumnDefinition Width="85"/>
                <ColumnDefinition Width="*" MinWidth="900"/>
            </Grid.ColumnDefinitions>
            <TextBlock x:Uid="DayProject" TextWrapping="Wrap" Text="Project" Grid.Column="0" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="7,2,0" Style="{StaticResource BodyTextStyle}" />
            <TextBlock x:Uid="DayTask" TextWrapping="Wrap" Text="Task" Grid.Column="1" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="7,0" Style="{StaticResource BodyTextStyle}" />
            <TextBlock x:Uid="DayFrom" TextWrapping="Wrap" Text="From" Grid.Column="2" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="7,0" Style="{StaticResource BodyTextStyle}" />
            <TextBlock x:Uid="DayTill" TextWrapping="Wrap" Text="Till" Grid.Column="3" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="7,0" Style="{StaticResource BodyTextStyle}" />
            <TextBlock x:Uid="DaySum" TextWrapping="Wrap" Text="Sum"  Grid.Column="4" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="7,0" Style="{StaticResource BodyTextStyle}" />
            <TextBlock x:Uid="DayNote" TextWrapping="Wrap" Text="Note"  Grid.Column="5" VerticalAlignment="Top" HorizontalAlignment="Left"  Margin="7,0" Style="{StaticResource BodyTextStyle}" />
        </Grid>
    </DataTemplate>

ItemTemplate中：

<DataTemplate x:Key="DataTemplate">
        <Grid d:DesignHeight="50" Margin="0,5,0" >
            <Grid.ColumnDefinitions>

                <ColumnDefinition Width="85"/>
                <ColumnDefinition Width="85"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <TextBlock HorizontalAlignment="Left" TextWrapping="NoWrap" Text="{Binding ProjectName}" VerticalAlignment="Center" Margin="5,0" Style="{StaticResource ItemTextStyle_sf}" Grid.Column="0" ToolTipService.ToolTip="{Binding ProjectName}"/>
            <TextBlock HorizontalAlignment="Left" TextWrapping="NoWrap" Text="{Binding TaskName}" VerticalAlignment="Center" Margin="5,0" Style="{StaticResource ItemTextStyle_sf}" Grid.Column="1" ToolTipService.ToolTip="{Binding TaskName}"/>
            <TextBlock HorizontalAlignment="Left" TextWrapping="NoWrap" Text="{Binding StartTimeString}" VerticalAlignment="Center" Margin="5,0" Style="{StaticResource ItemTextStyle_sf}"  Grid.Column="2"/>
            <TextBlock HorizontalAlignment="Left" TextWrapping="NoWrap" Text="{Binding StopTimeString}" VerticalAlignment="Center" Margin="5,0" Style="{StaticResource ItemTextStyle_sf}"  Grid.Column="3"/>

            <TextBlock HorizontalAlignment="Left" TextWrapping="NoWrap" Text="{Binding Note}" VerticalAlignment="Center" Margin="5,0" Style="{StaticResource ItemTextStyle_sf}"  ToolTipService.ToolTip="{Binding Note}" Grid.Column="5"/>
        </Grid>
