WPF share column width between separate grids

I have the following setup on my WPF UserControl:

<GroupBox>
  <Grid>
    ...
    <Grid>
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />

<GroupBox>
  <Grid>
    <Grid>
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="..." />

I'd like the second ColumnDefinition to be the same width as the first ColumnDefinition, but I don't want to set an explicit width. Instead, I want both grids columns to automatically stretch to the width of the longest piece of content in either grid column!

Is this possible?

It is possible by using SharedSizeGroup. Also check out IsSharedSizeScope.

<GroupBox Grid.IsSharedSizeScope="True">
  <Grid>
    ...
    <Grid>
      <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" SharedSizeGroup="A" />

<GroupBox>
  <Grid>
    <Grid>
      <Grid.ColumnDefinitions>
        <ColumnDefinition SharedSizeGroup="A" />

See here for more information.
