#460 – A GridSplitter Can Share a Cell with Another Control

When using a GridSplitter in a Grid, you often define the Grid so that the GridSplitter is located within its own row (for a horizontal GridSplitter) or column (for a vertical GridSplitter).  However, you can also place a GridSplitter in a cell with another control.

In the example below, the horizonal GridSplitter is placed in the first row (of two rows), with two Label controls.

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>

        <Label Content="Row 0 Col 0" Background="Azure" Grid.Row="0" Grid.Column="0" />
        <Label Content="Row 0 Col 1" Background="Lavender" Grid.Row="0" Grid.Column="1" />
        <Label Content="Row 1 Col 0" Background="Moccasin" Grid.Row="1" Grid.Column="0" />
        <Label Content="Row 1 Col 1" Background="Honeydew" Grid.Row="1" Grid.Column="1" />

        <GridSplitter Grid.Row="0" Grid.ColumnSpan="2" Height="3" Background="Blue"
                      VerticalAlignment="Bottom" HorizontalAlignment="Stretch" />

    </Grid>

Note that we add the GridSplitter as the last element in the Grid, to make sure that it shows up on top of the Label that it shares a cell with.
