Hello,

I have a simple grid with 3 columns (one of which contains a grid splitter). When resizing the grid and the left column reaches its minimum width, instead of doing nothing it increases the width of the right column. Could anyone help me stop this?

I can't set the max width of the right column, because the grid itself also resizes.

Here's some sample code that shows the problem. While resizing, move the mouse over the red area:

XAML:

<Grid DockPanel.Dock="Top" Height="200">
    <Grid.ColumnDefinitions>
        <ColumnDefinition MinWidth="200" Width="*" />
        <ColumnDefinition Width="3" />
        <ColumnDefinition MinWidth="120" Width="240" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <Rectangle Fill="Red" Grid.Row="0" Grid.Column="0" />
    <DockPanel LastChildFill="True" Grid.Row="0" Grid.Column="2" >
        <Rectangle DockPanel.Dock="Right" Width="20" Fill="Blue" />
        <Rectangle Fill="Green" />
    </DockPanel>
    <GridSplitter Background="LightGray" Grid.Row="0" Grid.Column="1" Height="Auto" Width="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
</Grid>
