Define two column in wpf,each column has a GridControl (left GridControl should take whole area if right GridControl is collapsed or take half area if right GridControl is visible)

I try to set ColumnDefinition (Width=auto or Width=*) but do not achieve the expectation

Try this:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <Grid Grid.Column="0">
        <Border BorderBrush="HotPink" BorderThickness="1">
            <TextBlock Text="Left Grid"/>
        </Border>
    </Grid>
    <Grid Grid.Column="1" Visibility="Collapsed">
        <Border BorderBrush="HotPink" BorderThickness="1">
            <TextBlock Text="Right Grid"/>
        </Border>
    </Grid>
</Grid>
