Setting columnDefinition and RowDefinition from style template? - wpf

Question

Is it possible to add the follow code:
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="*"/>
<RowDefinition Height="auto"/>
</Grid.RowDefinitions>
into a Style / Setter template for a Grid? And then automatically setup the RowDefinitions for a Grid like this?
<Grid style="{StaticResource MyRowDefs}">
<Button Grid.Row="0" Content="Button1/>
<TextBox Grid.Row="1"/>
<Button Grid.Row="2" Content="Button2/>
</Grid>

Do this solve your issue: How to create reusable WPF grid layout
For your example, you could do something like:
<Window x:Class="ReUseGridTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:ReUseGridTest"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Style x:Key="GridItemsStyle" TargetType="ItemsControl">
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemsPanelTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
</Grid>
</ItemsPanelTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<ItemsControl Style="{StaticResource GridItemsStyle}">
<Button Grid.Row="0" Content="Button1"/>
<TextBox Grid.Row="1" Text="Test"/>
<Button Grid.Row="2" Content="Button2"/>
</ItemsControl>
</Window>

You can't set the RowDefinitions property in a Style because it's not a dependency property but you can create a custom Grid type and use this one:
public class CustomGrid : Grid
{
public CustomGrid()
{
RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) };
RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
}
}
Usage:
<local:CustomGrid>
<Button Grid.Row="0" Content="Button1/>
<TextBox Grid.Row="1"/>
<Button Grid.Row="2" Content="Button2/>
</local:CustomGrid>
