Question

我无法在UI上看到任何我的堆栈面板，Data Grid占用了所有可用的UI空间。为什么？

  <Grid>
            <Grid.RowDefinitions>
             <RowDefinition Height="50"/>
              <RowDefinition Height="500"/>
            </Grid.RowDefinitions>
        </Grid>
 <StackPanel Grid.Row="0" Orientation="Horizontal" Background="Red"  >
            <TextBox Height="50" Width="250">t1</TextBox>
            <Slider></Slider>
            <TextBox>t2</TextBox>
        </StackPanel>
        <Grid Grid.Row="1" >
        <DataGrid   Name="DGComm" AutoGenerateColumns="False" CanUserResizeColumns="True" IsReadOnly="True" ItemsSource="{Binding LogMessagesList}">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Time Stamp." Binding="{Binding Date, StringFormat='{}{0:yyyy-MM-dd HH:mm:ss,fff}'}"  Width="0.1*"/>
              .
              .

        </DataGrid>
        </Grid>

不显示堆栈的原因 - 在将任何内容放入其中之前，您已关闭Grid标记。

<Grid>
        <Grid.RowDefinitions>
         <RowDefinition Height="50"/>
          <RowDefinition Height="500"/>
        </Grid.RowDefinitions>
    </Grid>

我假设您发布了有问题的XAML。请尝试以下代码

<Grid>
        <Grid.RowDefinitions>
         <RowDefinition Height="50"/>
          <RowDefinition Height="500"/>
        </Grid.RowDefinitions>

    <StackPanel Grid.Row="0" Orientation="Horizontal" Background="Red"  >
        <TextBox Height="50" Width="250">t1</TextBox>
        <Slider></Slider>
        <TextBox>t2</TextBox>
    </StackPanel>
   <Grid Grid.Row="1">
    <DataGrid   Name="DGComm" AutoGenerateColumns="False" CanUserResizeColumns="True" IsReadOnly="True" ItemsSource="{Binding LogMessagesList}">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Time Stamp." Binding="{Binding Date, StringFormat='{}{0:yyyy-MM-dd HH:mm:ss,fff}'}"  Width="0.1*"/>  
              </DataGrid.Columns>
    </DataGrid>
    </Grid>

     </Grid>

数据网格不允许任何其他控制
