GridSplitter resize next

问题

It seems I can't use GridSplitter to resize next item. Here is xaml:

<Grid>
    <!-- this works -->
    <Grid Background="Gray" HorizontalAlignment="Left">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100" />
            <ColumnDefinition Width="auto" />
            <ColumnDefinition Width="auto" />
        </Grid.ColumnDefinitions>
        <GridSplitter Grid.Column="1" Width="10" ResizeBehavior="PreviousAndNext" />
    </Grid>
    <!-- this doesn't -->
    <Grid Background="Gray" HorizontalAlignment="Right">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="auto" />
            <ColumnDefinition Width="auto" />
            <ColumnDefinition Width="100" />
        </Grid.ColumnDefinitions>
        <GridSplitter Grid.Column="1" Width="10" ResizeBehavior="PreviousAndNext" />
    </Grid>
</Grid>

and demo:

Notice what left Grid can be resized, while right one has some issues. You can try given xaml yourself to see what I mean.

What should I do to make next item resizing working?

回答1:

I made it work by changing ColumnDefinition Width

<Grid>
    <Grid Background="Gray" HorizontalAlignment="Left">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100" />
            <ColumnDefinition Width="auto" />
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <GridSplitter Grid.Column="1" Width="10" ResizeBehavior="PreviousAndNext" />
    </Grid>
    <Grid Background="Gray" HorizontalAlignment="Right">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="auto" />
            <ColumnDefinition Width="100" />
        </Grid.ColumnDefinitions>
        <GridSplitter Grid.Column="1" Width="10" ResizeBehavior="PreviousAndNext" />
    </Grid>
</Grid>

and another variant I like more:

<Grid>
    <Grid Background="Gray">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100" />
            <ColumnDefinition Width="auto" />
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="auto" />
            <ColumnDefinition Width="100" />
        </Grid.ColumnDefinitions>

        <GridSplitter Grid.Column="1" Width="10" ResizeBehavior="PreviousAndNext" />

        <Border Grid.Column="2" Background="Gold"/>

        <GridSplitter Grid.Column="3" Width="10" ResizeBehavior="PreviousAndNext" />
    </Grid>
</Grid>
