StackPanel childs 自动调整大小

Question

我正在尝试创建一个包含三个网格的表单，每个网格在一行中有 DataGrid 和 Button，在下面的一行中我有 GridSplitter 来调整内容的大小。我希望表单显示内容的大小与屏幕大小成比例。我知道 StackPanel 不会调整内容的大小，但我又需要垂直堆叠网格。

    <StackPanel Orientation="Vertical" VerticalAlignment="Stretch" Height="Auto">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
            </Grid.RowDefinitions>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>
                <DataGrid>
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="Col 1" />
                        <DataGridTextColumn Header="Col 2" />
                        <DataGridTextColumn Header="Col 3" />
                    </DataGrid.Columns>
                </DataGrid>
                <Button Grid.Column="1" Content="Btn" />
            </Grid>
            <GridSplitter Height="5" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Grid.Row="0" ResizeDirection="Rows" ResizeBehavior="CurrentAndNext"/>
        </Grid>

        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
            </Grid.RowDefinitions>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>
                <DataGrid>
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="Col 1" />
                        <DataGridTextColumn Header="Col 2" />
                        <DataGridTextColumn Header="Col 3" />
                    </DataGrid.Columns>
                </DataGrid>
                <Button Grid.Column="1" Content="Btn" />
            </Grid>
            <GridSplitter Height="5" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Grid.Row="0" ResizeDirection="Rows" ResizeBehavior="CurrentAndNext"/>
        </Grid>

        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
            </Grid.RowDefinitions>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>
                <DataGrid>
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="Col 1" />
                        <DataGridTextColumn Header="Col 2" />
                        <DataGridTextColumn Header="Col 3" />
                    </DataGrid.Columns>
                </DataGrid>
                <Button Grid.Column="1" Content="Btn" />
            </Grid>
            <GridSplitter Height="5" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Grid.Row="0" ResizeDirection="Rows" ResizeBehavior="CurrentAndNext"/>
        </Grid>
    </StackPanel>

Answer 1

我认为您需要创建一个有 5 行 (RowDefinition) 的 Grid 而不是 StackPanel，并且在每一行中放置您的表单并在下一行之后添加GridSplitter，我的意思是你最终会在第 2 行和第 4 行得到两个 GridSplitter。

试试这个修改后的标记版本：

<Window ...>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="auto"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <Grid Grid.Row="0">
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>
                <DataGrid>
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="Col 1" />
                        <DataGridTextColumn Header="Col 2" />
                        <DataGridTextColumn Header="Col 3" />
                    </DataGrid.Columns>
                </DataGrid>
                <Button Grid.Column="1" Content="Btn" />
            </Grid>
        </Grid>

        <GridSplitter Height="5" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Grid.Row="1" ResizeDirection="Rows" />

        <Grid Grid.Row="2">
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>
                <DataGrid>
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="Col 1" />
                        <DataGridTextColumn Header="Col 2" />
                        <DataGridTextColumn Header="Col 3" />
                    </DataGrid.Columns>
                </DataGrid>
                <Button Grid.Column="1" Content="Btn" />
            </Grid>
        </Grid>

        <GridSplitter Height="5" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Grid.Row="3" />

        <Grid Grid.Row="4">
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>
                <DataGrid>
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="Col 1" />
                        <DataGridTextColumn Header="Col 2" />
                        <DataGridTextColumn Header="Col 3" />
                    </DataGrid.Columns>
                </DataGrid>
                <Button Grid.Column="1" Content="Btn" />
            </Grid>
        </Grid>
    </Grid>
