How to create reusable WPF grid layout

Question

I have a window with tab control and number of pages - tab items. Each tab item has same grid layout - 6 rows and 4 columns. Now, each tab item contains grid with row and column definitions, so almost half of XAML is definition of grids.

How can I define this grid in one place and reuse that definition in my application? Template? User control?

Besides 6x4, I have only two more grid dimensions that repeat: 8x4 and 6x6.

Edit:
Forgot to mention: controls in grid are different for each tab. I just want to have grid defined once in some resource so that I can reuse them on different tab pages. Now XAML looks like this:

    <TabControl>
        <TabItem Header="Property">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition />
                    <RowDefinition />
                    <RowDefinition />
                    <RowDefinition />
                    <RowDefinition />
                    <RowDefinition /> 
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition />
                    <ColumnDefinition />
                    <ColumnDefinition />
                    <ColumnDefinition />
                </Grid.ColumnDefinitions>
                <!-- some controls here -->
            </Grid>
        </TabItem>
        <TabItem Header="Style">
            <Grid >
                <Grid.RowDefinitions>
                    <RowDefinition />
                    <RowDefinition />                        
                    <RowDefinition />
                    <RowDefinition />
                    <RowDefinition />
                    <RowDefinition />
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition />
                    <ColumnDefinition />                        
                    <ColumnDefinition />
                    <ColumnDefinition />
                </Grid.ColumnDefinitions>
                <!-- some controls here -->
            </Grid>
        </TabItem>

       ... and this repeats for several more tab items

    </TabControl>

This grid definition repeats for each tab item on the form. It annoys me that half of XAML is grid definition.

Is there a way to define this grid at one place and then reuse that definition?

The best way in my opinion would be to use ItemsControl with an ItemsPanelTemplate, since you need a container for multiple items:

<FrameworkElement.Resources>
    <Style x:Key="GridItemsStyle"
           TargetType="ItemsControl">
        <Setter Property="ItemsPanel">
            <Setter.Value>
                <ItemsPanelTemplate>
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition />
                            <RowDefinition />
                            <RowDefinition />
                            <RowDefinition />
                            <RowDefinition />
                            <RowDefinition />
                        </Grid.RowDefinitions>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition />
                            <ColumnDefinition />
                            <ColumnDefinition />
                            <ColumnDefinition />
                        </Grid.ColumnDefinitions>
                    </Grid>
                </ItemsPanelTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</FrameworkElement.Resources>
<TabControl>
    <TabItem>
        <ItemsControl Style="{StaticResource GridItemsStyle}">
            <TextBlock Grid.Row="1" Text="R1" />
            <TextBlock Grid.Column="1"
                       Text="C1" />
        </ItemsControl>
    </TabItem>
    <TabItem>
        <ItemsControl Style="{StaticResource GridItemsStyle}">
            <TextBlock Grid.Row="2"
                       Text="R2" />
            <TextBlock Grid.Column="2"
                       Text="C2" />
        </ItemsControl>
    </TabItem>
</TabControl>
