Question

I’m using a couple of Grids to format multiple GridViewColumn.CellTemplates:

<ListView SharedSizeScope='true'>   <ListView.View>     <GridView>       <GridViewColumn>         <GridViewColumn.CellTemplate>           <DataTemplate>             <Grid>               <Grid.RowDefinitions>                 <RowDefinition SharedSizeGroup='foo' />                 <!-- ... --> 

I tried to extract the RowDefinitions (which are the same for all columns) into a Style:

<Style TargetType='{x:Type Grid}'>   <Setter Property='RowDefinitions'>     <Setter.Value>       <RowDefinition SharedSizeGroup='foo' />       <!-- ... --> 

But the compiler complains:

Error: The Property Setter ‘RowDefinitions’ cannot be set because it does not have an accessible set accessor.

Which is kind of obvious, but not very helpful.

How could I avoid specifying the row definitions multiple times (see also Don’t Repeat Yourself) short of coding up a custom derivation of the Grid?

Grid doesn’t support control templates (info taken from here and, indirectly, from here).
