silverlight调整数据网格数据网格拆分器

Question

我正在尝试使用网格拆分器来调整网格行的大小，但是我没有得到我所期望的行为。

    <Grid x:Name="LayoutRoot" Background="White" Width="300">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <StackPanel Grid.Row="0">
        <StackPanel Orientation="Horizontal">
            <TextBlock Height="23" Text="Inventory:"/>
        </StackPanel>
        <sdk:DataGrid AutoGenerateColumns="False" Height="Auto" Name="dataGrid1" HorizontalAlignment="Left"  IsReadOnly="True" >
            <sdk:DataGrid.Columns>
                <sdk:DataGridTextColumn Binding="{Binding Name}" CanUserReorder="True" CanUserResize="True" CanUserSort="True" Width="Auto" Header="Name" IsReadOnly="True" />
                <sdk:DataGridTextColumn Binding="{Binding CreatedDate}" Header="Created Date" />
                <sdk:DataGridTextColumn Binding="{Binding ChangedDate}" Header="Last Edited" />
            </sdk:DataGrid.Columns>
        </sdk:DataGrid>
    </StackPanel>        
    <sdk:GridSplitter Grid.Row="1" Height="10" Width="300"  HorizontalAlignment="Stretch"/>
    <Grid Grid.Row="2"></Grid>
</Grid>

我希望数据网格调整其内容的大小，其中滚动条应该出现时，它的大小。

问题是你有一个StackPanel中的DataGrid。垂直方向的堆叠面板没有垂直边界，因此数据网格在不知道它将被裁剪的情况下呈现它的整个高度。你应该使用另一个网格来获得你想要的结果：

   <Grid x:Name="LayoutRoot" Background="White" Width="300">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Grid Grid.Row="0">
       <Grid.RowDefinitions>
           <RowDefinition Height="Auto" />
           <RowDefinition Height="*" />
       </Grid.RowDefinitions>
       <TextBlock Grid.Row="0" Height="23" Text="Inventory:"/>
       <sdk:DataGrid Grid.Row="1" AutoGenerateColumns="False" Name="dataGrid1" HorizontalAlignment="Left"  IsReadOnly="True" >
            <sdk:DataGrid.Columns>
                <sdk:DataGridTextColumn Binding="{Binding Name}" CanUserReorder="True" CanUserResize="True" CanUserSort="True" Width="Auto" Header="Name" IsReadOnly="True" />
                <sdk:DataGridTextColumn Binding="{Binding CreatedDate}" Header="Created Date" />
                <sdk:DataGridTextColumn Binding="{Binding ChangedDate}" Header="Last Edited" />
            </sdk:DataGrid.Columns>
        </sdk:DataGrid>
    </Grid>        
    <sdk:GridSplitter Grid.Row="1" Height="10" Width="300"  HorizontalAlignment="Stretch"/>
    <Grid Grid.Row="2"></Grid>
</Grid>
