如何将网格行拆分为两列？

Question

我有3行的网格布局.如何将第3行拆分为2列.

<Grid.RowDefinitions>
    <RowDefinition Height="0.75*"/>
    <RowDefinition Height="0.25*"/>
    <RowDefinition Height="36"/>
</Grid.RowDefinitions>

Answer 1

有两种方法可以做到:

• 使用嵌套布局.将另一Grid行放在第三行,并在该子网格中有两列.

  <Grid>
      <Grid.RowDefinitions> ... </Grid.RowDefinitions>
      <ThingInFirstRow Grid.Row="0" />
      <ThingInSecondRow Grid.Row="1" />
      <Grid Grid.Row="2">
          <Grid.ColumnDefinitions>
              <ColumnDefinition />
              <ColumnDefinition />
          </Grid.ColumnDefinitions>
          <ThingInLowerLeft Grid.Column="0" />
          <ThingInLowerRight Grid.Column="0" />
      </Grid>
  </Grid>
  

• 坚持使用一个Grid,给它两列,并使前两行中的东西跨越两列使用ColumnSpan.

  <Grid>
      <Grid.RowDefinitions> ... </Grid.RowDefinitions>
      <Grid.ColumnDefinitions>
          <ColumnDefinition />
          <ColumnDefinition />
      </Grid.ColumnDefinitions>
      <ThingInFirstRow Grid.Row="0" Grid.ColumnSpan="2" />
      <ThingInSecondRow Grid.Row="1" Grid.ColumnSpan="2" />
      <ThingInLowerLeft Grid.Row="2" Grid.Column="0" />
      <ThingInLowerRight Grid.Row="2" Grid.Column="1" />
  </Grid>
