This is my XAML:

<ListView ItemsSource="{Binding Items}">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Property1" DisplayMemberBinding="{Binding Property1}" />
            <GridViewColumn Header="Property2" DisplayMemberBinding="{Binding Property2}" />
        </GridView>
    </ListView.View>
</ListView>

I want these 2 columns to take up the width of ListView in 1:1 ratio.

How can I achieve this?

Edit: I found this suggestion on MS Connect. This would perfectly solve my problem. However it is closed as postponed (for 2.5 years now..)

What comes to mind is using internal Grids in the templates which each have a ColumnDefinition with the same SharedSizeGroup, the GridView should then have Grid.IsSharedSizeScope="True" and the columns of the grid view should themselves be unresizable (if that is possible), cannot test that right now so it's a bit sketchy.

Another method would be to bind both Widths of the GridViewColumns to the width of the ListView and then use a custom converter to get an appropriate fraction of that back.

  • +1, Potentially Blend could be used to discover what the "template" looks like for the `GridView`, which may enable restyling the columns. However, my gut says binding the `Width` to a converter set to half the `ActualWidth` of the `ListView` is probably going to be the only way without writing his own `ViewBase`. – user7116 Feb 08 '11 at 16:13
  • @sixlettervariables I tried exactly that and it gave me a horizontal scrollbar. I think I need something less than 2 halves. – Kugel Feb 08 '11 at 21:37
  • @Kugel: You could just force the scrollbar to be off, you won't be needing it anyway, it's just a pixel or two :P – H.B. Feb 08 '11 at 21:39
  • I tried the SharedSizeGroup solution and it had no effect. – Simon F May 02 '14 at 15:47
